Homework Statement
The Hawking/Bekenstein relation gives entropy S for a black hole as proportional to its area:
S = kc^3 / 4G hbar A
Does the entropy increase or decreatse when two black holes coalese into one?
What is the entropy change for the universe (in equivalent bits of information) when two solar mass black holes coalesce..?
Homework Equations
The Attempt at a Solution
Not sure what happens or how to work out entropy change..
What stays constant before and after? total mass?
Thanks
