Hubble has shown the world Trillions of things that are too far away to see with a regular, backyard telescope.
NASA invented Velcro and a ton of things we use everyday.
The International Space Station (ISS) brought several countries together to work on a very big, expensive, Scientific project. We have made a lot of Scientific discoveries in Chemistry, Physics, Biology, Geography, Astronomy and other branches of Science and Math on the ISS.
It's very expensive to launch a rocket into space. NASA has to spend over 1 Billion dollars every time they launch a rocket. That is money that goes to companies and people all over the US and the rest of the world. That's "trickle down economics".
NASA and other space agencies have proven from space that the world is not flat. Scientists can watch the weather from space. They can spot hurricanes, tornadoes, Tsunamis and other things long before they can harm anyone. They can see lightning hitting Earth. They have discovered that lightning actually strikes Earth between 50-100 times per second!
They have sent spacecraft's to every single planet. They learned that all the gas giants (Jupiter, Saturn, Uranus and Neptune have rings around them. The only one you can see with a regular telescope at home is Saturn's ring.
They've discovered signs of possible life on Mars and a few moons in the Solar system, but no proof yet.
They've put military satellites in space, as well as others for GPS, Astronomy, Geology, Google Earth, Weather, Earth's atmosphere, and other things.
They've sent signals to other planets, in hopes of aliens intercepting the signals a Million light years away. They are also listening for signals from aliens.
Metiors and other things are headed toward Earth. NASA wants to find a way to stop them from hitting us and preventing a mass extinction of humans. (That's what killed the dinosaurs.)
If we are no longer able to live on Earth, we must find somewhere else to go.
The government has set off nukes in space for Scientific and military purposes. (Maybe nukes can be used to save Earth from being hit with a Metior.)
A lot of new technology had to be invented to build rockets powerful enough to get humans to space and be able to survive up there. New, advanced technology had to be invented to communicate with Astronauts from the ground.
Voyages I and II are in interstellar space, going far away from Earth. They now know how big the Heliosphere is.
The temperature of space is close to Absolute Zero. Scientists have done experiments on the Space Station to get even closer to Absolute Zero than the temperature of space. They can get closer to that temp on the ISS than they can on Earth.
They have talked about sending regular civilians like you and me to space for vacation. I'd love to go up, but, it will be too expensive.
Scientists know the appropriate size and composition of all the planets.
Probes have been sent to Venus. They landed on the surface and they stopped working within a few hours. Probably because it's so hot that they all may have melted or the acid rain may have damaged them as well. Either way, NASA knows that they can never send humans up there.
Spy satellites have been sent up for military purposes over countries like Iraq. They also have some over the US for: Military, law enforcement and Science. (Who knows, the government of the US and other countries might be watching you right now!)
It is really a lot of fun to watch a rocket launch.
There's a lot of things that were built Thousands of years ago which nobody can figure out how to replicate them and build them the same way today, including the Great Pyramids. They probably had help from aliens.
Some of the Pyramids line up perfectly with Orion's belt.
This is only scratching the surface of all the good things that have come from the Space Program.

Nuclear Weapons
Nuclear Weapons:
If we ever do have a WWIII,
it won't necessarily be a nuclear war!
If there ever is a WWIII, it will very likely start out, the same way as WWII and a lot of other wars started: Just a regular, conventional war. Two countries will decide they don't like each other. Those countries will grab their guns, tanks, troops, etc, one country will invade the other. Then, those countries will ask for help from their allied countries and possibly even places like the UN.
Once other countries join forces, someone will decide to attack an innocent country that doesn't want to get involved, just like in WWII, Japan messed with the wrong country and got their butt kicked!
If, however, all countries play fair and obey the laws that say you can't use nuclear weapons at all, unless another country launches one at you first, then, no nuclear weapons weapons would be used at all in the first place! In the US, we can use them in retaliation for the use of chemical weapons by another country, against the US.
In fact, ironically, the US and most other countries that have nuclear weapons, including: Russia, Canada, India and China, just to name a few, have them and keep them well maintained and ready at all times to PREVENT WWIII from ever happening in the first place! NOT so that we can fight a nuclear war!
The US invented both Atomic and nuclear weapons.
Atomic bombs ended WWII, but, those are no longer used. Soon after the war, the US invented nukes. Russia soon followed, along with other countries.
Since the US and Russia didn't get along at the time that nukes we're invented, they thought, " since the US has nuclear weapons, we need to have them to, so we can defend ourselves."
The US did not teach Russia how to make nuclear bombs, they had to figure that out themselves. They did!
Once the US found out that Russia had their own nukes now, the US no longer had an advantage and had that much power over the Russians. The Two governments had to have a talk with each other now and they both agreed on one thing:
Mutually Assured Destruction!
The US President told the Russian government, "If you ever launch a nuclear missile on the US, it's over, because, if you launch even one at me, I'll hit you with a whole bunch of nukes!"
The Russian government said, "I understand that. The same applies to you! If you launch one at me, I'll do the same to you! Launch several more than what you launched at me!"
Either way, they both agreed, it would be a bad day and possibly the end of the world! They called it: "Mutually Assured Destruction".
Eventually, other countries learned how to make them to.
Bill Clinton wanted to make some kind of a trade at one time with N Korea. So, of all things he could of chosen to trade, he gave them the plans of how to build a working Nuclear bomb!
Russia eventually created the largest and most powerful nuclear bomb ever: The Tsar Bomba. Much bigger than any US nuke!
Then most countries around the world signed a treat saying that they will no longer test nuclear weapons at all. This includes testing of nukes everywhere: Above ground, under ground, above or under water, suspended or launched into the air or anywhere in outer space.
The problem with a treat, however, is that it is just a piece of paper with signatures on it. Most treaties only last a certain amount of time and they have to be renewed. When one President signs a treat for anything, that ruins things for every President after them! If the next President wants to test nukes, for example, in this case, now they can't, because, a former President signed a treat, making it illegal. Now the next Presidents after the one who signed the contract can't do it. But, they are going to think, "I should be able to do it, because my signature is not on that treaty! I'll find a loophole in the treaty and I'll do it anyway!"
Treaties get violated all the time!
There is a treaty that protects Antarctica. It says that nobody can drill for oil or test nukes or do other potentially harmful things on that continent. Also, nobody, except: Scientists, government officials, military and a few other, similar people are allowed to explore the Antarctic Continent. There are probably a few places where regular, civilian tourists can step foot on the land, just so they can tell their friends they have been to Antarctica and walk around on the ice glacier.
However, the easiest way to win a nuclear war would be to launch 1,000 nukes on Antarctica! That would cause massive flooding, Tsunamis and severe, global warming, just to name a few problems! But, that would kill Everybody in every country, rather quickly!
When you see the President on TV, you often see one person staying close by, with a brief case handcuffed to his wrist. That is because, everything in that brief case is so important, so top secret and would be very dangerous if it got into the wrong hands.
I don't know what all is in there, but, one of the most important and dangerous things in there is: The codes to all the nuclear missiles in the US and all of them that the US has in other countries.
Other countries know that the US President has easy access to the nuclear missile codes at all times, 24-7-365! That is another deterrent to the commies and terrorist countries launching a nuke at us.
The most recent nuclear weapons test is suspected to of been in North Korea, just a few years ago. They deny having ever built and/or tested a nuke. However, the US and a lot of other civilized countries are constantly watching N Korea. We are watching them from outer space, on the and under the ocean, from S Korea and other countries, etc.
It only takes the International Space Station about 90 minutes to completely circle the Earth! Don't you think Astronauts and Russian Cosmonauts could see the big mushroom cloud out the window of the ISS? However, that would be only, if someone were looking out the window at the right time and when they were over N Korea.
The satellites in space could also see it and, in several different countries, including the the US, they have devices that can detect the radiation and other things that are a tell tale sign of a nuclear explosion anywhere in the world. All the nuke detection systems around the world detected a nuclear blast somewhere on Earth. Nobody owned up to it. So it was investigated and, the evidence showed that it came from N Korea.
These days, there are some people who don't like nuclear weapons. They are trying to fight to get rid of them and have every country sign a treaty to get rid of all nukes and never make anymore ever again!
That's not going to happen!
Like I said before, a treaty is just a piece of paper! It is not worth anymore than the paper and the ink that it was signed with!
People and countries violate treaties all the time!
Besides, with so many unethical countries out there that support terrorism and they don't like the US or a lot of other countries, we better have something to defend our country's with!
Some countries, I would never trust, Even if they did sign a treaty like that! They'd sign it, but, still keep some nukes. The US needs to keep some nukes, just to prevent those countries from attacking.
However, there are a few countries that have signed a treat saying that they, in their own country, will not have any nukes. The government and people of those countries agree with and support the ban. Maybe, they are near other countries that do have nuclear weapons. In that case, if a nuclear missile we're launched on their country, it could hit one of those neighboring countries. Even if it hit the intended target, the radiation, fallout, explosion itself, etc would affect the countries next to them, so, those countries would probably retaliate by launching their own nuclear missiles.
If we ever do have a WWIII,
it won't necessarily be a nuclear war!

Jupiter.
The famous, Great Red Spot is about Three times bigger than Earth.
It is a large storm that's been going on for over 300 years. It is currently, slowly shrinking. It spins counterclockwise at about 225 MPH (360 KPH). It is comparable to a hurricane.
Jupiter would fit inside the Sun 9 times.
It has a faint ring system. Scientists did not know about the rings until the Voyager Spacecraft got there. Voyager showed the rings for the first time. The rings are too faint to be seen with a Telescope. In fact, I have a really powerful Telescope and I can't see the ring with it. University of Central Florida in Cocoa, FL has the second largest Telescope in the state of FL and they can't see it with that scope.
It has, as of now, 69 confirmed Moons. Probably, more to be found.
Looking through my Telescope, I can see the color bands on the planet and Six of it largest Moons.
Since, Galileo invented his own Telescope and looked at Jupiter, and discovered 4 of these same Moons (Io, Europa, Ganymede & Callisto), they are called: Galileo Moons. Those are Jupiter's largest moons. The rest are too small to see from Earth.
(Unfortunately, someone else invented the Telescope, just a short period of time before Galileo invented his telescope. So, he can't claim credit for inventing it.)
There are some very violent storms on Jupiter. Mostly inside the planet. Lightning on this planet is much more powerful than what we experience here on Earth. Scientists believe that it rains Diamonds inside of Jupiter. Because of the heat and pressure inside of the giant ball of Gas. But, they can't prove it.
The composition of the planet is mostly: Hydrogen, Helium and Ammonia. It's believed to have a rocky and metallic core.
Since the planet spins so fast, it completes one rotation in 9.8 Earth hours.
The rapid rotation causes Jupiter to bulge at the Equator. The diameter at the Equator is: 88,846 Miles (142,948 K).
The diameter at the poles is: 83,082 Miles (133,708 K). The Scientific name for this shape is: An Oblate Spheroid.
Jupiter is a Brown Dwarf. A failed star. Since it is made up of the same elements as most stars. However, it would have to be 75 times more massive to cause nuclear fusion of Hydrogen and turn into a star.
The color bands around Jupiter are created by strong 400 MPH (640 K) winds flowing East to West in the planets upper atmosphere.
Jupiter has a huge magnetic field, larger than any other planets. It is also the strongest magnetic field in our Solar System. It's almost 20,000 times strong than the one here on Earth! It is more than 1,000 times the lethal dose of radiation for a human. This magnetic field damages every spacecraft that goes near it, even if it is heavily shielded. The magnetic field extends out between 600,000 - 2 Million Miles (1 Million - 3 Million K) towards the Sun and forms a tail which extends over 600 Million Miles (1 Billion K) behind the planet.
At it's furthest point from the Sun Jupiter is 507.04 Million Miles away.
When it's closest to the Sun it's 460.24 Million Miles away.
It orbits the Sun at a speed of 29,205 MPH. Completing one rotation around the Sun in 11.86 Earth years.
The distance from Jupiter to Saturn depends on where they are in orbit. When they are on the same side of the Sun and at their closest point, they are approximately 5 Astronomical Units (AU) away from each other.
When they are on opposite sides of the Sun, they are about 15 AU away from each other.
(One AU is the average distance between the Sun and Earth. 93 Million Miles or 149,668,992 K).
Depending on where the Earth and Jupiter are in their orbits, Jupiter is between 4.2 and 6.2 AU away from Earth.
We are lucky to have a planet the size of Jupiter in our Solar System, because, being so big, it has a lot of gravity. It attracts a lot of Metiors and other things to it. So, rather than hitting Earth or the other planets, a lot of them hit Jupiter instead.
Imagine what might have happened if Shoemaker-Levy would of hit Earth.
The SL comet had been captured by Jupiter's gravity about 20 or 30 years before it broke into several large pieces and hit Jupiter in July of 1994. The fragments of the comet got too close to the planet on July 16, 1994. The first impact created a fireball larger than Earth! A total of 21 impacts were observed over the next six days. The largest one created a dark spot more than 7,456 Miles (12,000 K) across. The explosion it created was 6 Million Megatons of TNT. That's 600 times the worlds entire known nuclear arsenal at that time, according to: www.americaspace.com.
A comet or meteor that size hitting Earth would quickly put an end to all life on Earth! In fact, most Scientists believe that it was a large meteor that crashed into Earth 65,000,000 years ago that killed off the Dinosaurs.
For anyone asking: Why does the US need to have a SPACE FORCE?
I'm pretty sure there was a time when people said: "Why do we need a Navy? Why do we need an Air Force? What good are those going to do? That's a waste of money!
Why are they spending Billions of dollars creating Navy SEALs, Army Special Forces, Army Rangers, Delta Force and similar things? That's a waste of money! They are wasting my tax dollars on this!
Why are they spending so much money on building nuclear weapons? That could destroy the whole world in just a few minutes!
The enemy can and does attack the US and other countries from the air and water. That's why we need Air Force and Navy.
There's things going on in the world everyday that you and I will never know about. We have enemies all over the world. People are constantly thinking of things they can do to attack another country. Delta Force is a top secret military organization that, up until Clinton was in office, we weren't even supposed to know about. The government denied its existence completely. Bill Clinton hinted that there might be an organization like that, but that's all I'm going to say.
They are constantly protecting the world from terrorists.
Navy Seals and Special Forces take most of the missions that are way too difficult, dangerous and top secret for any other military units to take on.
SEALS killed Bin Laden, for instance.
The reason we have nukes is to PREVENT nuclear wars from ever happening in the first place. How? N. Korea, Russia, Iran and all other countries that don't like the US, they all know that the US invented both Atomic and Nuclear weapons. They also know that the US has more of them than most other countries. I'm sure there's probably a country somewhere in the world that probably has more than we do, but, the US has more than 99.999% of other countries in the world. They know better than to launch a nuke at the US or our allies. Because, the US can and will track their missiles coming in from tracking devices in space and on the ground. If they launch ONE single nuke at us, the President will first, launch about 20, multiwarhead missiles on their country and turn them into a pile of rubble!
Technology is changing really fast all over the world and we need a new way to fight crime, terror, illegal immigration, drugs, nuclear war, the list goes on and on.
Just like Science Fiction movies from the 1980's and even ling before that predicted, we would be in space by the year 2000. Well, we're late getting into space! 18 years late, but, it was inevitably going to happen.
Not only should we have a military presence in space, but also, a lot more Scientists should be up there studying the Earth and it's atmosphere.
As soon as the US gets a military presence in space, other countries will do the same. Our enemies will be up there to.
From outer space, you can see an entire continent, so, instead of an airplane flying over the ground between 300 feet to 5 miles off the ground, they have satellites and troops 20,000 miles or more above the ground. They will be able to look down and see everything. The enemy won't be able to hide very easily on the ground anymore.
The US and rest of the world will be forced to invent new technologies to keep up with the Space Force. When a Scientist tries to invent something specific, they will have to work on it for a long time. In the process, they will accidentally discover and invent other things. That is how we got the Lazer and the Microwave along with Millions of other things.
There is a lot of "Space Junk" flying around in space. It's all over up there. A lot is in orbit around Earth. That could crash in on us and cause a lot of problems. Space Force can protect us from that and try to find a way to clean it up.
They will watch for Metiors and yes, even UFOs!
Space Force will be above the atmosphere of Earth, so, they will have a better, much clearer view of outer space. That will help us study Astronomy, Physics, Chemistry and other things.
They can even send FBI agents up to watch down on the ground, not just in the US, but, in other countries to, and they can track criminals before they run too far away. Then, hopefully, it won't take 10 years to find them, like it did to get Bin Laden!
There's probably a Million other good reasons to have a Space Force.

Lightning can strike up to 20 Miles away from a thunderstorm.
When you see Lightning in the distance on a hot day, but, you don't hear thunder, that's because, there is a storm a long ways away. Too far for you to see the rain clouds or hear the thunder. This makes it look like the lighting is being caused by the heat. People often think it is the heat that is causing the lighting. It's often referred to as "Heat Lightning". But, Heat Lightning does not exist. It is regular lightning from a storm that's too far away for you to see the rain or hear the thunder.
Lightning strikes the Earth between 50 and 100 times per second! Astronauts have confirmed that as fact, because they can see the clouds light up in several different places around the world, all at the same time. They can see it from the space station.
Lightning can travel in all directions, most Lightning is cloud to cloud lightning and it doesn't hit the ground. On the ground it can travel straight down, up, or sideways. According to the Discovery Channel and some high speed video footage of lightning strikes, which you can see on YouTube, most Lightning travels from the ground up, NOT down from the clouds!
Lightning has between 1 Million and 1 Billion Volts.
In the movie: Back To The Future, they use the the word: "Jigowatt". There is no such thing as a Jigowatt. The actors mispronounced the word: "Gigawatt". Just like the computer term, Gigabyte- 1 Billion bytes, a Gigawatt is 1 Billion Watts.
When people get struck by lightning, they usually don't get hit directly by the bolt, usually, the lighting hits something else, if someone is touching the object that got hit, they get zapped. It can also "splash", or bounce off something it hits and hit someone. Sometimes, it hits the wet ground several feet away and if a person is standing on the ground near the strikes, electricity travels across the wet ground and hits them.
The record for the most times being struck by lightning lightning is 7 times! It was a park ranger. He lived to tell about it! However, he had Psychological and physical health problems after being struck that many times.
The lighting capital of the word as of 2016, according to NASA.gov, is: Lake Maracaibo in Venezuela. They get an avg of 233 lightning strikes per square Km every year.
Before NASA researched this, The Congo Basin in Africa held the record for the most Lightning activity each year.
NASA conducted their research with: "The Lighting Image Sensor" (LIS) on the Tropical Rainfall Measurement Mission.
The lighting capital of the US is Tampa, FL. They have more Lightning than any US city. The word Tampa comes from the Clausa Tribe in the 16th century. The word Tampa means: "Sticks of Fire".
The Lighting Belt is an area of FL that extends from Tampa to Orlando and from Orlando down to Ft Myers and Lake Okeechobee. That area of FL gets the most Lightning each year.
Lightning can generate heat up to 60,000 degrees F. That's 6 times hotter than the surface of the Sun!
Lightning kills more people than Hurricanes and Tornadoes combined every year.
NASA is not supposed to launch rockets through clouds, because, that could trigger lightning. However, I have seen them do it and the rockets did not cause lightning. Not the ones I saw.
Most commercial airplanes get struck by lightning at least once or more every year. Because of all the safety features on airplanes to protect the plane and passengers from lightning, most people don't even know that the airplane was struck by lightning. In fact, planes can even trigger lightning.
Experts say that if lightning hits your car while you're in it, you should be safe. The force of the lighting will be absorbed by the outer frame of the car and you, theoretically, should not be affected by it. Unless you stick your arm out the window and touch something else that is touching the ground, then you'll get fried.
Lightning can be produced by other things besides rain, Tornadoes, Hurricanes, volcanic eruptions, rockets and sometimes even a huge fire, which can also cause a fire tornado. That is a whirlwind caused by a fire. It sucks up the flame. Now the tornado is spinning around and it is actually spinning a flame around with it! Making it even more dangerous.l
Some other planets have storms on them and some of them also produce lightning. Jupiter has some of the most violent storms in the Solar system. According to NASA, Lightning on Jupiter is much more powerful than what we experience on Earth.

Black holes in the center of the Milky Way Galaxy.
The way most most Supermassive Black holes form is by "eating" other black holes, stars and other things. Everything that the black hole consumes adds more mass to it and the black hole grows. The more it eats, the bigger the black hole becomes. Most black holes start out as small ones. Then they suck things in it and they become bigger.
The way they form in the first place is:
A giant star runs out of Hydrogen and other forms of fuel. It collapses and what's left over is a black disk that has an immeasurable amount of mass. In fact, according to Einstein, a black hole might have an infinite amount of mass. However, I find that hard to believe, because it sounds impossible for anything to literally have infinite mass.
The Sun is a Medium star. It doesn’t have enough mass to form a black hole. Scientists measure other stars, black holes and other really large objects in space with. "Solar. Masses". One solar mass is the mass of the Sun.
In order to form a black hole, a star has to be at least 5 solar masses.
There are a few black holes that Scientists have found which they think are Millions or Billions of solar masses. These are called: Supermassive Black holes. There is one in the center of every spiral galaxy, including the Milky way.
The gravity from these Supermassive black holes helps hold the galaxies together.
Scientists are not sure exactly how Supermassive black holes form. However, one reason might be that it could of consumed Thousands of other black holes and planets and kept getting bigger.
The gravity from a black hole is so strong that almost nothing can escape from it. Even if something traveled at the speed of light, it would not be able to escape from the gravitational pull of a black hole. That is why they are hard for Scientists to find.
However, Stephen Hawking discovered a type of radiation that does manage to escape from black holes. Since he discovered it, this radiation was named: Hawking radiation. Astronomers need special, X-ray telescopes to see it.
This technology is so new, that until recently, nobody had ever actually seen a black hole. They knew they existed, because they could see stars, planets and other things getting sucked into them. Hopefully, with the newer, X-ray telescopes, Scientists will actually be able to get a picture of a black hole for the first time ever! Astronomers have been talking about trying to do that this year (2018).

Aliens in the Milky way Galaxy.
The Milky Way Galaxy is approximately 100,000 Light Years across. We are are near the far end of one side. If aliens have tried to contact us all the way from the other side and they were 90,000 LY away, their message wouldn't reach us for 90,000 years after the day they sent it. That is only if they used a Radio Telescope like Scientists use here on Earth. That's because radio waves travel at about the speed of light thorough space.
Assuming they are much more intelligent and much more advanced than Humans and they've invented a UFO that can travel ten times the speed of light and they are also able to survive the G Force, it would still take 9,000 years to travel to us.
They could also have a time warp or, better yet, use Einstein's theory of "Bending Time and Space", which is only theoretically possible, where you could bend two points in space and bring them together. Then they would be able to pull our Solar System to wherever they are and just fly across within only a few Seconds! That would be so cool, but highly unlikely.
However, there's also a small chance that they will be less intelligent than us and they can't even figure out how to get off the ground of their own planet. I doubt that though. But, if that were true, or even if they had a big spaceship traveling towards us from 90,000 LY (27,607 Parsec) away, we still wouldn't be able to see them with the world's most powerful Telescope, which is called: "The James Webb Telescope". It will be much more powerful than the Hubble. They haven't even sent it up yet. NASA will launch it up within a few years. I don't know how, unless they get our space program going here again by that time. Otherwise, they will have to contract it out and have either one of the civilian agencies like Space X do it or Russia may have to send it up for the US.
If the aliens are outside of our Galaxy, they will be able to get in the Milky Way to visit us, but it will be extremely difficult for us or them to get out of our Galaxy. Because, the Milky Way is so big, and so strong that, Because of all of its gravity and several other forces of Physics, which I don't understand, you would have to travel about 1.2 Million miles per hour to get out of the Milky Way! That is the Escape Velocity of the Milky Way Galaxy.
If you did get out though, you may have a much easier time getting back in, but, since the spiral arms of the galaxy are rotating pretty fast, the whole galaxy will be flying away from you through space and our entire Solar System is moving through the inside of the galaxy, if you did get back inside, you would be a long ways away from where you started from and you'd be far away from the Earth. Good luck finding it again!
Personally, I believe aliens have already been here, who do you think built the Pyramids 5,000years ago? As well as Crop Circles and other things.
(BTW, one Parsec is approximately 3.2 Light Years.)

What if you were the only person left on Earth?
(My reason for writing this is: To explain what life would be like if you lived forever and never died, but, you were also the only human left on Earth.
I've often wondered what that would be like. I wanted to write a book about it. But, that proved to be harder than I thought I'd be. So I just posted a short story on my blog, rather than an entire novel.)
Imagine what it would be like if one day you made a wish that you would live forever. Then one day something strange happens and every human gets really sick and dies all over the world in one day, that is, all except you! Now you will learn that, sometimes, you have to be careful what you wish for, because you just might get your wish!
Since every person on Earth just died at the same time, strange and catastrophic things instantly start to happen all around you. You were just walking around town in New York City with 5 of your close friends at the time it happened. Suddenly, your friends all start complaining of having chest pain. You look around and see everyone else walking down the sidewalk or driving their car is having chest pain to. You're confused, because you feel fine. About one minute later, every person you see just falls down dead!
Thousands of cars crash all over the road.
There is almost no electricity, except for places that have their own generators, solar power or other sources of electricity. So 99% of all the lights go out around town.
Now you are getting scared and lonely.
It only takes about a minute for airplanes to start falling out of the sky and crashing into the ground and buildings. The pilots and everyone else are already dead, so nobody's left to fly the plane.
You think, "Since everybody's dead, I might as well take all their money." That's actually a good idea, because, you may need it to start a fire to keep warm.
Now that you're the only person left, money is worthless!
While you're stealing everyone's money, you also steal other things: Guns, keys, jewelry, tools, medical supplies and anything else you can get.
Since the illness only affected people, not plants or other animals, most of the zoo animals escape from the zoo. They are scared, hungry and mad. They start wandering around the city, searching for food and shelter. Most of them start eating dead people. But a few Pythons, Elephants, Lions, wild dogs, Monkeys and large birds start chasing you. The animals back you into a corner of a building. You can't run, because vicious animals are blocking your way!
You quickly grab one of the guns you stole from a dead guy. Instinctively, you point the 357 Magnum at the largest bully, in this case, it's the Elephant. You cap off one bullet into its head. But, that doesn't stop the beast. He's even angrier now. You pull the trigger again, but the gun jams! You throw it on the ground and grab another gun, this time, it's a 9 mm. You manage to kill all the hungry animals.
But, now you have more problems. Satellites are crashing into the atmosphere from space. They explode when they hit the Earth's Ionosphere. Chunks of metal and other debris are raining in all around you. You run into a building. Some pieces of the satellites crash through the roof at 100 MPH, almost hitting your head!
Because of all the things happening at the moment, most of the buildings have caught on fire!
Without thinking, you grab your cellphone and call the fire department. Then, you realize that there is no phone service! All the firefighters and people at the phone company are probably all dead to!
You quickly run down to the Subway to take shelter.
You notice there's no light down there. You grab a lighter out of your pocket. But you smell a strong oder of natural gas and dead bodies! Realizing that it would be a bad idea to use it, you put the lighter away, so you don't blow the place up. You continue walking through the dark and stepping on dead bodies. You hear strange noises, then something is biting your ankle. With no people around, the rats are free to run all around and one of them just chose you for its next meal!
Continuing to feel your way around in the dark, you notice the Subway train has jumped off the tracks and tipped over,after having run over about 50 dead people!
You are starting to go crazy with anxiety and scream for help because there's nothing else to do! "I can't stay here." you think. But, if you go upstairs, the zoo animals will eat you alive!
You stop and think for a minute and remember that you were a Green Beret in the US Army for 10 years. Utilizing your Special Forces training, you manage to hide and evade the ferocious animals. You walk quietly up the stairs and find a car that is not wrecked. You drive home with hopes that your family's still there. You soon get home and find that your entire family is dead!
Now you just get more depressed and scared.
You jump back in the car that you just acquired and drive to the grocery store. When you get a mile down the road, you find a case of beer and a large bag of Marijuana. Realizing that there's no cops around to stop you, you start drinking the beer and smoking weed. It calms your mind for a while.
When you arrive at the local Walmart, you walk around in the dark, trying not to step on all the dead bodies! You grab all the food and beer that will fit in your car. Then you realize that all the perishable food will be moldy and rotten soon and nobody is around to restock it.
When you leave the store, you drive around to clear your mind and look for any other human survivor. But, you drove 250 miles and now you are low on gas. You get to the nearest gas station and the pumps don't work! You find another car, hotwire it and drive away. This car was not the best choice, because when you hit the brakes, they don't work! The car won't stop! Since you didn't use the seatbelt, the vehicle crashed into a truck that was hauling dynamite and you go flying through the windshield! You were driving as fast as the car could go (about 300 MPH). You suffer several broken bones and other traumatic injuries. Then the dynamite blows up. You are severely burned in the worst pain you've ever felt. But, you are a former Green Beret, so you remember what the Army taught you about pain: "Suck it up and drive on!" You try your best to ignore the pain, like your Sergeants taught you in Special Forces.
You manage to keep walking despite the pain, broken bones and major blood loss.
You realize that there's not a single doctor that can help you now. But, you find a needle and thread, stich yourself up and force your bones back into place.
As you keep walking, you decide the pain is just too much for you to take. You find some rat poison and eat a whole box of it. Then you shoot yourself in the head with a 44 magnum.
The gun knocked you to the ground and put a big hole in your head, but you didn't die! Remember your wish: "I wish to live forever!"
This is just day ONE of the rest of your life! Things will only get much worse from here!
For example: Eventually all the buildings will collapse. There will be severe rain and snow storms. Meteors will hit the Earth. Nuclear power plants will meltdown. You'll get old and sick, but nobody can help you. There will be another ice age that might last 1,000 years or more. Cars and other modern things we have today won't work forever.
The Sun will swell up to become a Red Giant. It will completely swallow up Mercury and Venus. It will get so close to Earth that it will be to hot for anything (except you) to survive here. Then it will collapse into a very densely packed, very heavy, small and cold, White Dwarf star.
The Moon will either float away, crash into Earth or explode. Whatever happens to the Moon won't be good. Without the Moon, life would not be possible on Earth! But, I'll write a blog about that later.
In about two or three Million years, the Milky Way Galaxy will crash violently into the Andromeda Galaxy. The two galaxies will merge and become one giant galaxy called the "Milkomeda Galaxy".
The entire Universe will eventually die out. Everything will fall apart. The atoms of literally everything will start to separate and all that will be left is a mysterious substance that Scientists don't understand, they've never actually seen it and they don't know exactly what it is, it's called: "Dark Matter".
The Dark Matter will will disappear eventually to. Leaving nothing absolutely nothing behind in the Universe.
You will be left floating around in a place that used to be known as "outer space. But, you will have no air to breath, no food or water and no human or or other living companions left!
Of course you will still be alive, because, remember, you asked for it!
Eventually, you get lucky though, a wormhole opens up and transports you to another dimension. A world that is really strange. Nothing is the same as it was in your old Universe. All the laws of Physics, Chemistry and other forms of Science and Math are completely different in the new. Universe.
Even though you do meet some new friends, they are aliens from the new world and they don't even speak your same language. Now, all your English and any other human language you speak is totally useless, however, within a few years, you learn the new alien language.
But, in a few Million years, everybody will die off there to, everyone except you and you will end up in the same situation again!
I can't explain what Dark Matter is, because even Scientists don't know what it is. However,Scientists do know that something exists that we can't see. Most of what we call "Empty space" might not be empty, it might be full of Dark Matter. Scientists even think that Dark Matter, whatever it is, could the most common substance in the Universe and outer space along with the space between planets and Everything right in front of your eyes that is not a solid or liquid object that you can see, the space between you and that visible object might be full of Dark Matter. If that's true, then about 99% of the Universe is all Dark Matter!
I've often wondered what that would be like. I wanted to write a book about it. But, that proved to be harder than I thought I'd be. So I just posted a short story on my blog, rather than an entire novel.)

Proof that UFOs DO EXIST!!
There are a lot of people in the world who don't believe that life exists anywhere else in the Universe.
Some of them say it is just physically impossible.
I disagree. I truly believe there is life on other planets all around our Universe.
Let me explain why:
People often say, "Scientists have found Billions of stars all around the Milky Way and all over the Universe that have planets orbiting around them. However, most of these planets are either too close to or too far away from the star to sustain life. Or the star is too big and hot. The planet appears to be too young or old or Scientists have not detected any water or Oxygen on that planet."
I have heard all the big excuses as to why people just don't want to believe in extra terrestrials. None of those arguments make any sense at all to me!
When people tell me it is physically impossible for life to exist on any of those other planets because....... Then they give me any of those explanations above or any others, this is how I explain my reasons for believing in UFO's and aliens.
To the people who think that it is impossible for life to exist on any other planet because Scientists have not detected any Oxygen or Water on those planets, here's my argument against that theory:
These people are only going by the Biology, Chemistry, Physics and other things that most people believe to be true on our tiny planet we call Earth in our small Milky Way Galaxy. Scientists discover new things here all the time. They've also proven a lot of Scientific "Facts" and theories to be wrong. For example: They've discovered some types of bacteria, viruses and other microscopic forms of life that can survive in boiling water, freezing temps and with or without water and oxygen. They've also found some that can adapt to and survive in artificial atmospheres of things like: Ammonia, Co2 and other gasses that would be deadly to humans. We don't know and can't prove how much Oxygen was in our atmosphere 65 Million years ago, when the Dinosaurs were here, but, Scientists do know for sure that there was a lot more O2 and less CO2, Carbon monoxide and other toxic gasses, because humans weren't around creating all those harmful gasses with cars, industrial emissions and other things. Also Dinosaurs were so big, they needed more Oxygen than we do to survive. If we humans were to live in an environment with 10 times more Oxygen than we have today, we'd have to be much bigger than we are, or we would die. If we had less, we would be smaller. Since there are a few organisms here on Earth that can live without water and oxygen and in extreme temperatures, it makes sense to say that there could be some life forms on other planets and other galaxies that could do the same.
Galaxies only contain about 1% of everything in this huge Universe. The rest is out in open space. We don't have a clue about what another, alien life form would require to survive in their world. Just because almost everything here on Earth requires Oxygen and Water to survive, doesn't mean that every alien species in the entire Cosmos would be required to have those things to live. My guess is they might require some different things to live. Maybe they would die if they were exposed to Oxygen and Water. Take, for example, the AIDS Virus, it can survive inside the Human body, but, what happens when it gets out of the body and it's exposed to air? It will only survive for a very short period of time, then within only a few minutes or less, it dies!
The Universe is so big that even with the Hubble Telescope, we can only see a small percentage of it. We don't know what things are like out there far away from us. Even if another intelligent life form is out there and has built up some large cities on another planet 1,000 Light years away, we will never be able to see them and their cities through a telescope from Earth. They will probably never be able to see us from their world either. We are just too small to be seen through a telescope from a long ways away. If there is life out there somewhere else in the Universe, and I'm sure there is, it doesn't mean it has to be an intelligent life form living on the land; it might be a simple, single celled form of bacteria living in the water or some other form of liquid on another planet. That would still be considered a form of “Alien Life”.
Also, consider this: Our world is so small, that our Solar System is just a tiny, insignificant, microscopic dot on the cosmic map. We are sitting in the Orion Arm near the outside of the Milky Way Galaxy. The entire diameter of our Solar System, from the Sun to Pluto and even beyond that all the way to the end of the Heliosphere is less than one light year. The Milky Way Galaxy is approximately 100,000 light years across. There are Millions or probably Billions of other galaxies that are much larger than ours. To make things sound even smaller, Scientists say that you could fit all the other planets, including Pluto inside the space between the Earth and our Moon. Jupiter is so big that more than two and a half Earths would fit inside its Great Red Spot. 1,324 Earths would fit inside Jupiter. About 980 Jupiters would fit inside the Sun and Thousands of Suns would fit inside of the star VY Canis Major. In fact, if that star were placed in the center of our Solar System, it would extend almost all the way out to Jupiter.
Our Universe is somewhere between 13-15 Billion years old. So far,this is the best estimate Scientists have for the age of our Universe. It might be much older! When the James Web Telescope gets up into space, it will see much further than the Hubble. That might make Scientists rethink the Universe's age. They will probably say it is older and larger than they thought.
Scientists believe the Universe is expanding at the speed of light or faster! If this is true and the Universe is expanding at the speed of light (186,282 Miles/299,792,458 M per second), the Universe is expanding one light year (5.878 Trillion Miles/9.4607E+12 KM) every year. That would put the far end of the Universe somewhere around 14 Billion light years (4.29241 Gigaparsecs) away from us.
Since there's not a single telescope in the world that can see much of anything at a distance of 14 Billion light years, we will probably never know who or what is out there that far away. I asked an Astronomer how big of a telescope would I need to see aliens on a planet: Four light years away, 100 light years away and 15 Billion light years away. His answer was shocking. To actually see aliens on a planet Four light years away, you'd need a telescope with an apreture, the opening at the end of the telescope that let's in light, that was over 100 miles in diameter and Just a few miles long. 100 light years away, your telescope would have to be a little bigger around than the Sun and a few miles longer. 15 Billion light years away, you'd need a scope about the diameter of the Milky Way Galaxy (100,00 light years from one end to the other) and probably 3 or 4 light years long! That is the minimum size scope you'd need. Even then, if you saw aliens at those distances, with the sizes of telescopes he recommended, the aliens would only appear as the size of small dots in the scope. Also, if you saw aliens from a distance of 65 Million light years away, the image you see would be what it looked like on that planet 65 Million years ago, NOT what it looks like there today! So, if aliens 65 Million light years away from us looked down at Earth with a really powerful telescope, they would actually see Dinosaurs- not Humans! In other words, give it up, you will never be able to make a telescope powerful enough to see aliens on another planet!
When you look up at the night sky, you can only see a very short distance. Almost everything you see is inside the Milky Way Galaxy. Except for the Andromeda Galaxy. That is 2.5 Million light years away. It is between 1.5 & 2 times the size of the Milky Way, so it can be seen with the naked eye. There's probably a few other things you can see outside of the Milky Way without a telescope, but, not much. With a good telescope, you can see way beyond our Galaxy, but, you cannot prove or disprove the existence of life.
SETI (the Search for Extraterrestrial Intelligence), NASA and a bunch of other places have been sending out radio signals to specific areas in space where they think life may be. But, radiowaves travel the speed of light. So, they will take 2 and a half Million years to get from Earth to the Andromeda Galaxy. To get to a star 5 Billion light years away, that's how long it will take to get there. Humans will probably be extinct by that time! They will only be able to receive the messages if they have a radio telescope that can pick up our Earthly signals. Then, their message they send us in response will take the same amount of time to get back to us.
NASA has, however, received just a few mysterious signals from space that they suspect, might of come from intelligent life forms in space. (For the best example, Google the "WOW SIGNAL".)
Humans have only been sending radio signals for about 50 years or less. It will take a long time for them to get to their destination.
Throughout history there have been thousands of people who have claimed to have seen UFO’s. There are even hieroglyphic drawings on the walls of the ancient pyramids of UFOs. That was long before humans ever learned how to fly. Of course, half of those sightings were probably just Meteors, Comets and similar things, but, those objects can only travel in one direction, they don’t have several different colored lights all over them, they don’t shoot laser beams and transport rays, they are not perfectly round and shaped like you would expect a UFO to be shaped and they don’t have little green aliens climbing in and out of them.
Thousands of people around the world who have never met each other have claimed to seen UFOs and had alien encounters. Some of these people even claim to have been abducted. A lot of their descriptions of the UFOs and aliens have matched almost exactly!
Astronomers have discovered Thousands of what they call: “EARTHLIKE” planets in the Milky Way and all over the observable Universe. These planets are close to the size of Earth, close enough to a star that is not too big or too hot to sustain life.
Years ago, there was something mysterious that crashed out of the sky and landed in Roswell, NM. Nobody knows for sure what it really was, because, right after it crashed, the US Military was right there cleaning it up! They loaded it all up and took it away to a top secret location. Most people think they took it to Area 51. Then they found the only guy that saw it and forced him to get on TV and say it was a weather balloon. More than likely, they probably, threatened to break his legs and kill his whole family if he ever told anyone what he really saw! It would be like the Government to do that stuff, think about it, how often has the government ever been 100% or even 1% totally honest about anything? The answer to that question is somewhere between 0% and never!
For a long time, there have been strange things popping up around the world called “Crop Circles”. Several people have tried to take the credit for them, just so they can become famous idiots! But there is so much evidence to prove that humans did not make them. For instance, there are no human footprints or tire tracks around them. Nobody ever sees or hears them being made. They show up in several different countries in the same night. People can’t travel across the ocean fast enough to do this in more than one country in the same night. Every time people go somewhere, they leave something behind, it might be trash, cigarette butts, lint from clothes, finger prints, footprints or something else, but, there is usually no evidence left behind to show that humans were ever at the scene where the crop circles are appearing. The circles are almost geometrically perfect. Humans would have a very hard time making a huge circle that perfectly round. There is a strange type of radiation that has been detected inside these circles. Sometimes the crops that have been made into a circle are magnetic.
The pyramids were built between 5,000 and 10,000 years ago. Nobody knows exactly how or why they were built. Nobody has been able to duplicate them now, not even with modern technology, physics and Engineering. Who taught people how to make them that long ago? Also, who helped them carry the huge rocks, some of them weighing over Ten tons, from the mines to the building sites? It was probably aliens from outer space.
These are the main reasons why I believe in UFOs. I know some people will still disagree with me. I challenge you to do your own blog about why you disagree with me. But, Just be ready to explain your reasons as to why you don’t believe in UFOs and give any Scientific evidence you have to support your belief.
