But to have the volume of material that we can see in the universe - all the stars, planets, galaxies, and associated debris, and then include a theoretical dollop of all that is beyond our vision, there must have been a helluva creation event - or perhaps it is an ongoing phenomenon (my theory) which is (somehow) turning (unknown) energy into matter before it moves on to the further reaches of space even as it stretches the boundaries of space farther out. I need a good moniker for this, “big bang” is a wonderful marketing word - I don’t have that for my concept.

Let me try another visualization. There is a rubber sheet of unimaginable proportions. There are lots of workers stationed around the perimeter and they pull at the sheet all at the same time, all in the direction opposite the center.

The center would remain (more or less) in the center, but everything would be moving away from it as the sheet stretched. Indeed, the closer you are to the edge, the more the sheet would be stretching, (and if it would tear, it would most likely be somewhere near the edge where the force is strongest, I would think.)

That is a two dimensional model, of course, but it should be easy enough to scale up to three dimensions in your mind; and transfer over to “the universe” and we find that everything, including “space”, is moving away from everything else, and more rapidly the farther away we can see. Galaxies farther away are separating more rapidly than galaxies closer to us, etc.

(I point out that this is a “me” centered universe, and it would be interesting to know if what we see, i.e. “everything moving away from everything else at increasing speed” is the same for everyone else in the universe. Alas I suspect we’ll never know that one.)

The “balloon” illustration of the universe misstates things because only the balloon is moving, indeed the air molecules inside the balloon are actually being compressed closer together by pressure. So, in my marketing world “big bang” or “balloon” would have to be replaced with “infinite rubber sheet”.

OK, I don’t think that’s gonna grab the popular zeitgeist. I’ll keep working on it.
