Another idea: at the end of times, when black holes finish merging into one giant black hole, will it force a big bang like event? If we assume the universe to be a large 3d sphere, what's the topology of space in it if it's just one giant black hole?

Why would all black holes eventually merge? The mass in our observable universe is constantly decreasing, with more and more of it going forever beyond our reach. For any two distant black holes it seems more likely that they will eventually find themselves forever alone in 'their' universe than that they will merge.
