From “Time Will End in Five Billion Years, Physicists Predict”, National Geographic Daily News:
The problem with a multiverse is that anything that can happen will happen an infinite number of times, and that makes calculating probabilities . . . seemingly impossible.
. . .
Physicists have been circumventing this problem using a mathematical approach called geometric cutoffs, which involves taking a finite swath of the multiverse and calculating probabilities based on that limited sample.
. . .
What a real-world cutoff would look like and what form the end of time would take are unclear, the team says. If it happens, it would probably be sudden and unexpected.
