My point is simply that it isn't productive to speculate on the terminal evolution of the universe based on a theory that is almost certainly incorrect. It is possible that some moderate adjustment of the big bang/inflation model will make it fit reality, but it is just as likely that the entire concept will have to be thrown out. If that happens, who knows what the new parameters will be? Meanwhile, why generate angst over purely hypothetical events that might happen billions of years in the future?
