Okay. Is it possible that our observable universe is only a small part of a system that is swirling around it's own gravitational pull and that there are other systems that are doing the same? Are we able to see expansion in all directions? mfb, I'm not a scholar and I don't understand...
Is it possible that our universe is just one of more universes and that our universe just appears to be expanding because we are actually merging with another universe? Just wondering if it would be a plausible explanation. Maybe the pull from the other universe against the pull from ours...
