« on: Yesterday at 22:05:01 »That is incorrect as the density of matter in our real infinite universe is fixed over time.
Not according to the Big Bang theory, it isn't.
This could be correct ONLY if you shrink the observable Universe while there is no change in all infinite universe outside that observable universe.
Not so. All areas of the Universe would shrink more or less equally.
So, how we prove that only the Observable Universe shrinks?
There's no need to.
Now do you think that as we go further and further back in time, the Universe M could shrink to zero (or close to zero) in just 13.8 BY?
Possibly. It depends on the maximum possible density (whether or not that density is infinite). Universe M would have been an awful lot smaller at the Big Bang either way.
If not, then as the total Universe is infinitely-large at this point, it would still be infinite even if we shrink it by go back 13.8BY in time.
That was my entire point. It demonstrates how the Universe as a whole can be infinitely large at the moment of the Big Bang even though our observable Universe was still incredibly tiny.
