Why does that suck? If the dark energy is truly a cosmological constant, then the universe will approach a small but non-zero temperature in the far future. This non-zero temperature means that there will be quantum fluctuations that will produce new regions of space-time periodically within our own. A heat death universe is not the end except in the sense that it is the end of our universe. A recollapse scenario would just bring about the end of our universe more rapidly.
Chalnoth, can you provide any supporting material for your speculative ideas?
