10E65 if protons do decay. 10E(10E76) if protons do not decay and virtual black-holes do not exist. At about 10E(10E(10E56)) the universe should spontaneously create a new universe, so that that is the most upper limit of time in our universe. Fairly small actually, compared to things like Graham's number and Tree(3). Turns out, infinity is really big. https://en.wikipedia.org/wiki/Timeline_of_the_far_future https://en.wikipedia.org/wiki/Timeline_of_the_far_future https://www.youtube.com/watch?v=XTeJ64KD5cg https://www.youtube.com/watch?v=XTeJ64KD5cg
