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 don't have a mass E=0xC2 then light should just "stop" of cease to exist

but that's 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 $$p = h\nu$$, where nu is the frequency and h is Planck's constant, and its energy is pc.

The riddler
To answer your second question, black holes do eventually end due to a process called Hawking radiation (Radiation emitted from a black hole due to quantum effects).
