What is Black Hole?

[unleashed]

When the star ten times more massive than our own Sun, explodes (Supernova) it leaves behind the strangest phenomenon in the Universe. The Black Hole. After explosion what is left behind is heavy core of subatomic particles, a Neutron Star. It can be very small, but with enormous density. Scientists calculated that approximately one teaspoon of Neutron Star would weight around billions of tons. The gravitational pressure of this highly dense object is so large that it can bend fabric of time and space. This theory is based on Einstein's proposition that space and time are woven together in a flexible fabric. Massive objects like Sun warp the fabric of space and time and pull smaller objects like Earth. Very large Neutron Star can warp time and space fabric so much that it could create a hole where gravity is so strong that not even light could escape. Black Holes are pulling everything around them closer to the center of the hole. In some sense black holes are creators of the galaxies since they are pulling planets and stars towards the spiral center. Each galaxy has a Black Hole and occasionally galaxies collide together because of the gravitational pull from the larger black holes. It is expected that in 5 billion years Andromeda galaxy will collide with our Milky Way galaxy.

"black holes about 10,000 to 18 billion times heavier than the sun are thought to exist ..."

They are very massive and are moving ... if any of the many black holes that form from dying stars come remotely close to the earth we would be devastated by the loss of our orbit and we would then die out as well

If a Black Hole moved in on Earth, it would bring the sun with it. If they figure that a mere teaspoon weighs so much, imagine a black hole thats the size of a car or something bigger. But, if you enter a black hole, do you just disintegrate or come out through what they call 'Light Holes' Which are black holes, but emit light, which may mean objects in black holes warp to light holes.

To be honest, I think thats what happens. Or your transported to some random spot in the universe.

Like worm holes?

[george]

Yes, like worm holes.

[unleashed]

Well same doubt as David. Can you explain it a bit George?

[george]

Black Holes?
Light Holes?
Other?

All of those I can at least attempt to explain.

I really like this thread, It's always nice when you can not only be informed, but also get knowledge, from these type of blog, nice entry. Thanks
