How is a black hole created? Why cant light get through it? Whats inside of it? And whats on the other side of it?
A black hole is created when a massive star, running out of fuel, can no longer support its own gravity and begins to collapse in on itself. When this happens to a super-dense object, the result is an area of space with such high gravity that anything approaching it -- radiation, matter, light -- is pulled towards it.
There is not "inside" or "other side" to a black hole, however, because it is not truly a hole. The name is used to refer to the fact that, since no light can be reflected from a black hole, it is effectively invisible when looked at with the naked eye.
It will never, as wika suggests, "become a white dwarf." A white dwarf is a star that has lost most of its mass but continues to retain some residual heat as it dies.
As an object approaches a black hole (from the perspective of the falling object anyway) every bond within every atom of the object becomes nullified as tidal forces rend matter and energy down to their smallest component parts. Basically, in the instant before you reach the center (the singularity), you become a mist of quarks (or smaller).
From the perspective of an outside observer, however, thanks to gravitational time dilation, you would appear to fall towards the singularity forever, never reaching the center.
Any other questions concerning the universe just funmail me!
a big star will become a suppernova then a blackhole or neutron(small star)
stars give of a lot of gravity which kepps our solar system togeter ... I assume when it expoldes there is so much gravity that everthing gets sucked up
To be blunt, nevets, you'd have a better grasp on both evolution and astronomy if you perked up a bit more in science class.
oh great so thats whats going to happen to us on wednsday wait how can it cause a black hole earth isnt a planet
