FIRST OF ALL, the universe didn't expand- ISNT expanding, and will never collapse. your opinions are well thought out however the universe well (life) started when there was nothing except your average space cloud, asteroids, and the start of all this, dead stars. at one point in time a fairly large star died leaving behind its core, alot of stars do this after the red giant stage i beleive. anyway this burnt out core of iron or whatever was large enough to have its own gravitational force. this attracted various adrift space rocks and other cores to collide with the main, dead core. eventually it formed a small planet. this planet came to be hit extremely hard by a huge meteor, and it split into chunks, each chunk large enough to have its own gravity. You get what im saying? this process continued to form the sun as we know it today, and eventually our earth. supernovas, black holes - all of it came into existence in time as stars that were alive collided with one another and created such things. Eg; black holes. and the honest truth that i stick by is that the "universe" has always been here, and so has time and space. When you say the universe is expanding, that also means it has a DEFINITE size. so then that would mean you could travel in space for one direction and eventually exit the universe?? No. It isnt legit and to add to this, people say that when all life dies that time stops. My response is Yes AND no. 1. Time is a system created by humans so yes when we all die, nobody will be there to KEEP TRACK of time. 2. HOWEVER when everything biotic (living factors) in the universe die, The whole thing in a way starts over again. our dead planet and sun will collide, break apart, explode, and create maybe even more planets that support life. and then that new "life" will die out and the process shall repeat itself.
I really hoped this helped someone! like it if you agree with me
