No, that is not true. There are millions upon millions of black holes, not just one.
In a black hole, gravity is so strong that nothing, not even light, can escape. This means that whatever goes into a black hole is trapped inside forever, making the saying "what happens in a black hole stays in a black hole" true.
A black hole? well scientist are not sure. Black holes is a theory, not proving to be true. But there could be.
no! that is not true because perganacy has nothing to do with space or a black hole
True
No. Once an object is pulled into a black hole, it is converted into gravitational energy.
No its not true.what really happens is that you die.duh
A black hole is not a true vacuum, as it contains matter and energy that we do not fully understand.
Black holes do exist - they are just VERY difficult to detect.
This is NOT true. Black holes are formed when massive stars explode in supernovas, blowing much of the star into space and crushing the core into a black hole. One of the things that WILL happen is a massive pulse of x-rays and gamma rays.
There is strong evidence that there is a black hole in the center of Milky Way, but there is no reason it should have a mass ejection in 2012
it is said that there are black holes in space which we have discovered is true and how gravity realates to a black hole is well, a black hole is said to suck away other universes we have not discovered yet gravity pulls things to the ground and a black hole uses that same pull force to suck in universes
For a stellar black hole, yes. Mass cannot be created or destroyed. Generally a black hole will be less massive than the star from which it formed, as much of the star's mass gets blasted when the star dies in a supernova. A black hole can gain mass over time as matter falls into it.
