When recent calculation found that the universes expansion was accelerating and that our galaxy would eventually be by itself zooming off ever faster forever. By the way, galaxies are not expanding, and if they go off by themselves I think they will probably collapse into a one galactic black hole. Anyway, I almost immediately knew that it could not fly apart forever. Things in the universe repeat. 35 or 40 years ago, I knew that explosions also implode, so I knew that there was a incredibly massive black hole at the site of the big bang before I even knew what a black hole was....So now one starts thinking....o.k. we had this big bang. It didn't just come from nowhere (unless God did it,and one could argue, (not me of course) that he could have done the even bigger universe that I believe in, also) so it had to build up over time...now you think, 200,000,000,000 star galaxies turning into the ultimate depleted uranium rounds going at some incredible speed away from the our big bang center....added to that, you think there are other big bangs out there shouting this way (I am waiting for someone to discover one of these "rounds" coming this way). You wonder how many would it take to make this work......If anyone were to ask me, I would guess, an infinite number of big bangs, and for a big bang to blow, build up and blow again...I don't know...maybe a trillion years??I've never written any of this stuff down before. I really like doing it.All my love, Your DadP.S. Jim, How is your Dad doing?
