In an infinite universe, there are infinite possibilities.
Anyway, multiplying universes in an attempt to splict the inexplicable smells like violating Occam's razor to me.
I would agree.
Yes, exactly! Much the same way the visible size of the earth is only 6 miles in diameter to a guy standing on a raft in the middle of the ocean.
Or that what we 'see' is not necessarily how things really look.
... and the older the light is when it finally gets here.
Only in a 'relative' way.
We now know the universal expansion is indeed slowing down, but not fast enough to ever fully stop it.
Well, if 'they' are going to pick one answer, then that one was the 'safest'. : )
we know just how big the 'observable' universe is, some 26 billion light years across. That's our "six mile" horizon. We know there's more out there and we know we'll never see it.
Best summation of our current knowledge in layman's terms I have yet to see.
Only if the fabric reaches the limit of its stretch, and doesn't break. I'm with you, I would assume yes, it fills up. If 'the bough breaks' the sight of space and matter above the break snapping back would be impressive to say the least! We have evidence that this has happened, a cosmic inflation event that occurred within a few moments of the Big Bang itself.
We may be just a pimple on God's rear that popped.
If our little speculations here have any validity there's a Nobel prize awaiting someone with a better grasp of physics and math than I'll ever have! No only would it provide a physical explanation of that troublesome faster than light expansion, it would also tell us just how much strain the universe can take, a handy thing to know if one ever hopes to rip a hole or two in it to enable FTL travel...
OK, now my head hurts.
Couldn't have done it without you asking a deceptively simple question,
I'm a pretty simple guy.
