it only matters to us
it likely has no end..we just don’t know for sure, since the universe is 13.8b years old, the light from that time hasn’t reached us yet..
but if the Big Bang is true, being that there was a beginning, then it would have to be finite…but again noevidence has presented itself for this claim either…
we don’t even know the shape of our universe… bubble? donut? flat disc? Our current tech that measures our universe points to flat but aren’t accurate enough to be definite
Einstein today wld be crazy interesting to listen to
Based on the Law of Conservation of Mass, there was also something there before the Big Bang, it was just extremely dense. The universe could be eternal.
