It is my understanding that with the passing of time, space actually
expands in size. In about 14G years, space will be twice its current
size.
What will this do to black holes (BH)? If a BH is in intergalactic
space and has nothing to consume, if space actually expands, the
density of the BH should become 1/2. What happens to the event horizon
in this case? Would this cause the BH to eventually disappear, similar
to Hawking radiation?
