How can the big freeze be a viable option for the end of the universe? The big freeze suggests that one day the universe will expand to such a large size that stars will fuse all the existing hydrogen in the universe and just leave black holes and other remnants behind, eventually reaching maximum entropy, resulting in a cold and dark universe. But quantum mechanics states that subatomic particles always pop in and out of existence due to vibrating strings through 11-dimensional hyperspace. The fact of that alone should tell us that hydrogen atoms will NEVER cease to exist, since they are just made up of a simple combination of protons, neutrons and electrons, which are always being created. I'm very confused with this. Both theories seem to contradict each other, yet most scientists are at general consensus with each of them. Dr. Michio Kaku, Co-founder of m-theory even agrees with the big freeze.
