The way I think about it (I could be wrong, I'm no expert) is that the distance between objects in space is both shrinking and expanding at the same time.
So there are two opposite things that are happening at the same time:
Shrinkage
The shrinking is due to gravity and is dependent on how much mass is in that part of space, and how far away the other object is from that mass. That shrinkage of space diminishes the further away you get r^2, so when you are close the shrinkage is really quick. When you are far away the shrinkage is minute.
Expansion
The expansion of the universe is minute but it happens everywhere, irregardless of whether mass is in that part of the universe or not. This expansion is accumulative. So the futher distance two objects are from each other, the higher the rate of expansion.
Both combined
When objects are close to each other the shrinkage due to gravity is quicker than the accumulative expansion over that short distance hence those objects move closer and closer together.
But when objects are really far away from each other then the shrinkage due to gravity is really small and the accumulative expansion over that vast distance is large, so those objects move further and further away.
Does that make sense?
It let's me know how you are thinking about it. Thanks.
I saw a picture of the universe where there were several (or many multiple) large empty spots, 100's of millions of light years across, where space is a complete void, totally empty, etc, and where these empty spots would have quote/unquote "walls", was where all the normal matter and material was that we are much more familiar with, etc, and I proposed that these large empty spots are actually responsible for the expansion that is a constant inside each spot, equally everywhere, on the rest of the universe, that never changes, etc. And even if the expansion was occurring at the speed of light, though I suspect it's a bit slower than that, etc, these empty spots are 100's of millions of light years across, in a universe that we can see that is 46.5 billion light years away from us in every direction, or 93 billion light years large, etc, but even if it was happening at 1 times the speed of light, even if it were happening that fast, etc, it's actually very, very, very slow for these empty spots and for the rest of the universe on those scales, etc, like slower than dirt at those scales almost, etc, which could mean that even a very weak gravitational force for "everything else", while at the very same time all being kind of pushed together by these empty spots, etc, anyway, I was wondering if even a very weak gravitational force, could be drawing "everything else" together? And maybe drawing everything else together, probably around these spots, towards a single center maybe, etc?
But thanks for letting me know how you think though. Because I do understand what you are saying, ok. Strong/weak forces, and all of that, etc. I wanted to let you know I do understand that, ok.
God Bless.
