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?

Proving the existence of other Big Bangs

I believe evidence of other Big Bangs (AKA Other Universes) can be found within our Big Bang (AKA Our Universe).  (I'll use BB for Big Bang in this post). As we know, our BB is expanding and the expansion is accelerating.  Likewise all the other BBs are expanding the same way and some of their Galaxies will have entered our BB. As we know all our Galaxies are moving away from the place at the center of our BB where the original explosion occurred.  The Galaxies that enter our BB from other BBs will be moving in different directions than all our Galaxies. Some would pass through our BB and some would be captured by the massive Black Hole created by the original explosion of our BB.  These Galaxies would add to the mass of this Black Hole and eventually expand it until it explodes, creating another Big Bang.  This is a simple description of a very complex process. 

It is my belief that the only thing that can create a Big Bang is it's interaction with other Big Bangs.

The Galaxies that enter our BB have come a long distance and have been off by themselves for a very long time. They could have collapsed under their own gravity and therefore would not be seen in a telescope  but could certainly be detected as massive Black Holes. Finding them would prove the existence of the other BBs.

First we found other stars. Then we discovered our own Galaxie.  Then we discovered a couple hundred billion other Galaxies.  I believe we will soon discover an infinite number of other Big Bangs AKA Universes.
