INTERESTING FACT

Black Hole Facts

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.

I hope the above helped with any confusions

A black hole CANNOT be seen, but scientists know that they exist because of their interactions with other bodies in space. For example, a black hole formed around a star. then the black hole would suck gas from the star. The gas would form a disk. This is called an accertion disk. This disk glows because of the huge amount of friction caused by rotating at high speeds with other gas. This paroduces visible light, but mostly X-rays. Scientists can detect those X-rays

this stuff is soooooooooooooooooooooooooo confusing.

i dont understand any of this stuff

That is all very good GEORGE and i'm not disputing the theory at all, in fact I agree with it fully but until a black hole has been seen it cannot constitute a FACT, but only a THEORY.

Thanks! :D

Take a red giant star. If we could go inside where temperatures are over a billon degrees Fahrenheit, helium and carbon would fuse into different heavier elements, like carbon and sulfur. The reaction eventually creates iron and the core quits burning. This causes the star to implode and go super nova, crushed by its own gravity into a brand new star.
A neutron star is left over. Its very small but very dense. About a teaspoon full weighs about a billon tons. If the neutron star is heavy (about three times as massive as our sun) enough the implosion continues and the neutrons themselves are crushed and a black hole forms from the remains. Its like the dead corpse of the star if you think about it.

Ok I have a little homework for all of you. Can someone tell me how scientists get pictures and know all these "so called facts" about black holes. How they get pictures when they have yet to detect black holes?

Mallory at 09:52PM, Feb 25th 2010.

simple and good......
as i expected....

arvind at 12:24AM, Feb 11th 2010.

although this is theoretically correct and has been proven to be mathematically possible, it does not constitute a FACT because no one has ever seen a black hole.

i WISH I WAS A STAR! i like rainbows!

They stop when they run out of mass. Black holes are also constanly spitting x rays out of their 'north' and 'south' poles. so, they are constantly loosing mass. A black holes will just dissipate or vanish when it dies.
