This video about deep time is pretty interesting: https://www.youtube.com/watch?v=uD4izuDMUQA

Melodysheep (the creator) has some great stuff on the topic.

Epic - this fits into category 2 with the "big crunch" situation, but the nothingness / heat death of the universe one also seems possible. I think the gravitational pull of a supermassive black hole consisting of all black holes in the universe would probably overwhelm the expansion force and draw everything into it, but who knows.

Very cool - thanks for sending.
