What would happen if a black hole swallows other black hole or if a Black hole swallow a white hole?

Answer 1

The answer is, if a black hole 'ate' another black hole, it would gain more mass, therefore it's event horizon(or area of influence) would increase. Once you cross the 'event horizon' it's a gravitational no return. Per the White Hole: It is found in theoretical science only. There has no proof of any white hole found (there has for black holes.) White hole ideas are not accepted by mainstream physicists, but a white hole may be the end product of the transmission of black hole matter in some part of the universe. If white holes exist the connection of a black hole to a white hole might actually be a wormhole or tunnel through 3 dimensional space. Black holes do have size and mass: if they did not have size, the difference in the size of the event horizon between black holes would not exist. The size of a black hole can be defined several ways - the gravitational force it generates (the mass), the physical size of the even horizon, or the size of an accretion disk (if there is one.) The problem most people have with the size of a black hole is that the very center of the black hole is a singularity: something that has no physical properties we can understand: it is so different that the word had to be made to describe it. In the sphere shells around the black hole are: the rest of the universe, "empty" space, matter and energy being bent (but not falling into the black hole), matter and energy falling into the black hole, (these 2 often show as an accretion disk), then the event horizon where the gravitational force is so strong now that even light can no longer escape, then the inner shell after the event horizon and this falls all the way down to the center, the singularity. Everything but the singularity has size, mass and is hot compared to the rest of hte universe (empty space again.) A black hole is an amazing thing but not a magical thing - it would probably be better if we used the term earler used - frozen star: one that no longer gives off heat.

Answer 2

Everything a black hole 'swallows' is bigger than itself because a blackhole is something that has negative mass, it takes up minus-space if you like. It is a very complicated process to understand but basically black holes 'swallow' things by making them cease existence and this is done by reversing magnetic charges.

Answer 3

What happens is one of 2 thinks one the black hole sucks the other black hole up or it makes a bigger black hole.

Answer 4

a black hole could merge with a black hole, and give out supernova

Answer 5

Yes.
