I'm curious as to whether or not there's any biblical explanation for what happens after the final judgement. From what I've read, the Christian apocalypse involves the final judgement of all people on earth, implying everyone is sent to either heaven or hell for eternity , followed by a 1000 year reign of the messiah. But then what? Our current scientific understanding of the universe implies that it should continue existing for many many many years beyond that regardless of what occurs to the entirety of the human race/earth. Does it continue existing without us? Is it re-made? Is it destroyed?
Also, what happens to humans that are on other planets during the apocalypse? Do they experience the same apocalypse on Mars as is described in revelation to happen on Earth? Do they experience it at all?
