Wow. Yes our universe had a beginning and you are right it may go on forever. I don't believe it will but I could be wrong
Observations suggest that the expansion of the universe will continue forever. The prevailing theory is that the universe will cool as it expands, eventually becoming too cold to sustain life. For this reason, this future scenario once popularly called "Heat Death" is now known as the "Big Chill" or "Big Freeze".
These are questions scientists don’t have definite answers to yet. Many think it’s likely you would just
keep passing galaxies in every direction, forever. In that case, the universe would be infinite, with no end.
Some scientists think it’s possible the
universe might eventually wrap back around on itself – so if you could just keep going out, you would someday come back around to where you started, from the other direction.
If you could watch for long enough, over millions of years, it would look like new
space is gradually being added between all the galaxies. You can visualize this by imagining tiny dots on a deflated balloon and then thinking about blowing it up. The dots would keep moving farther apart, just like the galaxies are.
Is there an end?
If you could keep going out, as far as you wanted, would you just keep passing by galaxies forever? Are there an infinite number of galaxies in every direction? Or does the whole thing eventually end? And if it does end, what does it end with?
The answer is we don't know. Scientist think the universe is eternal? I didn't know that. I don't agree. I think eventually it slows down and shrinks.
The universe will become extremely dark after the last stars burn out. Even so, there can still be occasional light in the universe. One of the ways the universe can be illuminated is if two carbon–oxygen white dwarfs with a combined mass of more than the Chandrasekhar limit of about 1.4 solar masses happen to merge.
But ultimately, gravity will reduce all stars to a super-dense state as black holes, neutron stars or cold white dwarfs. We already see galaxies in which the stars all appear quite old and there no longer seems to be any interstellar gas out of which to build new stars.
Imagine a universe with just earth, moon and asteroid debree. Dark. All these small stars turn into black holes. The whole thing collapes in on itself, bam, another big bang.
Just spitballing. Just like you. Could be. We don't know. You say god, this could be.
But you claim to have met this god so I can't even have a realistic conversation with you. You're sure there's a god because you've talked to it.
