Black Holes

Black holes are like the vaccum cleaners of space, and nothing, i mean nothing can escape them.

Black holes are created when the chemical reactions in the stars (fusion) runs out and the stars collapse under their own weight, thus creating a black hole.

Black holes are just extremly condenced mass which means that it has an extremly strong gravitational pull. In fact it is so strong that light can't even escape it and light travels at approximatly 186,000 miles per second ( thats almost as fast as my awesome car), and light is the fastest thing in the universe. So any object that comes within a certain distance to a black hole is automatically doomed because there is no possible way that it can escape its gravitaional pull. They just might be the strongest force in the universe.

Since black holes come from stars and our sun is a star then evetually in about 5 billion years our sun will also turn into a black hole, but if that happened we wouldnt even be around to see it because when a star is about to collapse it turns into a red giant which would swallow our solar system all the way up to venus.

Lets say that if a star were to collapse even 25 light years away from us, we would be doomed because black holes move (100,000 km/hr) and we would also know the exact time (hundreds of years in advance) when our world would come to an end. If that were to happen it would outshine anything in our sky because when a star collapses at one moment itsd brighter than all the other light in the universe combined. But we most likely wouldnt get to se our world get sucked into a black whole, we wouldve got killed a long time ago from the gamma radiation coming from the explosion which would burn off our o-zone layer. If our o-zone layer got burned off we would be getting horrible sunburns even if we were inside and we would all go blind and evetually die.

But lets say you did make it through the o-zone layer burning up, and you made it long enough for the arrival of the black hole, then you would get scked into it ( and thats not exactly an enjoyable experience). It would literally rip you apart, piece by piece, because as you get closer to the center of a black hole even feet has a signifigant difference, so if you were getting sucked into a black hole, there would be more pull on your head than your feet so you would literally get ripped apart.

There is of course an opposite to a black hole which hasnt been 100 percent proven but has strong theories behind it. It's called a worm hole/white hole which is where the stuff that came into the black hole is pushed out, but of course into billions of little pieces but it would still come through. Scientist theorize that black holes are rips in the space time continum ( yea thats a super geeky word), and that they actually connect us to different universes. And the stuff that gets caught in our black holes comes out in some other universe out of a worm hole. Thats actually one of the theories of how life came to this universe, it actually came from another universe through a worm hole.

So basicly black holes are like giant vacuum cleaners that suck up anything and everything. They could mean the end to our world as we know it, but we dont have to worry about it because thats not going to be for a very very long time. =]

The Beginning!

The Big Bang,
As most scientists view it as, the beginning of the universe is called the "Big Bang", they say our universe is approximatly 13 billion years old. At first the universe was a singularity in an empty space, and at some point in time an explosion happened and from that sigularity came an infinite place called the universe where time and space was created.
We have evidence and can trace back the big bang to the 10^-43 of the first second after it happened, so almsot to its starting point but not quite, we know that at first the universe was infinitly hot, and the super force is created which consists of the strong nuclear force, the weak nuclear force, electromagnetic, and gravity, this was called inflation and the universe was increasing at a rate greater than the speed of light. Then at 10^-32 of the first second after it happened the universe cooled down to 10^27 degrees celcius (thats really hot) and the universe at the point was known as the Quark soup because it was just electrons and other particles. Then at 10^-6 of the first second the universe dramaticly cooled to 10^13 degrees celcius, at that point clumps of protons and netrons started to form. After 3 minutes the universe has now cooled to 10^8 degrees celcius, but unforutanlty it was still too hot to form atoms or let light penetrate. The we jump to 300,000 years after it happened and it has finally cooled down to 10,000 degrees celcius, and finally hydrogen and helium atoms start to form ( our first elements) and light can shine (so the universe was pitch black for the first 300,00 years). After 1 billion years gravity (every object has gravity, even us) starts to for helium and hydrogen clouds that evetually will become galaxies and stars. The after 12 billion years its cools to -270 degrees celcius and planets and heavy elements start to form.
