I am at this point waiting to see someone prove that we aren't.
Though ultimately I don't know if it matters. What we have is so vast that we can't really fathom it ending except in the abstract. No matter how big a ripple I make in the pond it's not going to matter in a couple billion years. I content myself by thinking in centuries.
Which is precisely the sort of behavior one might expect if they lived inside of a black hole.
