what happens when to black hole crash into each other?
They merge and make one bigger black hole.
do black holes ever end, or do they just keep sucking everything in?
and in what happens all that light in a black hole? it must be very bright in the center of a black hole
in theory light goes fast when it comes into contact with a black hole, E=C x C2
but if light dont have a mass E=0xC2 then light should just "stop" of cease to exist
but thats just my theory
We don't allow personal theories on our science forums. There's a procedure for getting them posted on a special forum. Light has momentum and energy, but not mass. Its momentum is [tex]p = h\nu[/tex], where nu is the frequency and h is Planck's constant, and its energy is pc.
To answer your second question, blackholes do eventually end due to a process called Hawking radiation (Radiation emitted from a blackhole due to quantum effects).
