Is it possible that there are various / multiple universes out there [the so-called multiverse], and that each individual universe behaves somewhat like a human body behaves - it takes birth, it lives its course, and then the constituents which formed it are broken down and released back to the ecosystem [that is, to the multiverse] for reconstitution into a new body [a new universe]? A human body is also composed of billions or maybe trillions of constituent cells / particles. I don't know the answer, nor does anyone else, but it's worth pondering.
