I hope that suggested theory is false even through, very obviously, we wouldn't have to concern ourselves with it for a very long time if true.
Perhaps, If it is true, by the time the end is about to happen, we would have fingered out a way to hop safely into another universe? -that could be assuming an awful lot though.
We've always been doomed, though. Fates to choose from at the Cosmology Buffet:
1) The universe ends in fire with a Big Crunch.
2) The universe ends in ice by expanding forever, but decelerating whilst asymptotically approaching the entropic state of "heat death".
3) The universe ends in total disintegration as it expands forever at an accelerating
rate, the stretching of spacetime causing all bonds to break right down to the quarks comprising every last hadron.
#3 is the hot new thing blowing the dresses of physicists up these days, I think. And it appears to be corroborated by observation. Thus, I would say it's really good news if the universe turns out to be unstable and is consumed by a fresh, young universe before wholly disassociating into an eternal inky oblivion.
