But that could be true for our region of space, our "enclosure" (which wouldn't truly be closed, but part of a wider fabric) would eventually come to an end, like bubbles in a foam, popping, and re-growing from the redistributed matter
I know only my very most rudimentary cosmology though, but I really like... the dea... of the universe being... beyond our zome of comfort, so to speak.
If our "region" of space, our "bubble of expansion" is part of a wider "ocean" a wider "landscape", that stretches across distance as well as time infinitely, that would be SO frustrating, SO contrary to our comfort, that it would in a fun way be the most interesting outcome
Also, I always love to glide an eye over at religious people, like - it's all God's creation. It is God's undeniable purpose for His Children to traverse all of it - all of it - all of it - now, then and before. That's a LOT of spreadding the good word they have ahead of them
