There seem to be a fair number of Chinese physics papers on arXiv now, and this one about the variety of possible "rip" ends of the universe is quite interesting. They come up with their own - the "Quasi Rip", but I'll paste this from the introduction (clicking on it may, or may not, make it more readable):
Anyway, The paper then goes on to suggest a "quasi rip" is a possibility, from which the universe may rebuild. It also acknowledges that all of these ideas are currently up for grabs, in terms of being consistent with observations of the universe. I wonder for how long that will be the case.
