I think the universe has a limit, because it would break some laws. For instance, if the Universe is indeed infinite, wouldn't that break thermodynamics laws? Where does it get infinite energy to keep expanding indefinitely for ever and ever? Or thermodynamics just applies to humans because we're primitive? Huh?
So yes,
there's gotta be an end to it.
When it reaches it's limit, everything will stop, even time. And yet I think there's something beyond the infinite limit of the universe! Maybe "
we didn't had that much energy to keep expanding at beyond the limit, good luck next time, try again".
I really can't imagine that... it's beyond my current understanding. I mean, I can get some sort of idea on just how big the universe is (observable and beyond our current observations are) ... but thinking that there's this
limit, a border if you will, a wall, whatever... and then something else on the other side... is just unimaginable to me. What would that be on the other side?
So, having in mind that the universe is BILLIONS OF LIGHT YEARS WIDE... how sure are we that our universe hasn't started a "self destructive" mode? Because something that took billions of years to expand, would equally take billions of years to return to it's original point, right? Because that's the principle behind old stars and galaxies, that they're billions of light years away and when we see them it's because their light took that same amount of time to reach us, and suddenly we discovered that the same star, or galaxy we saw with our toys because their light reached us, has been long dead...
So with that idea... could it be possible that we've already reached the real limit and the universe it's begun its way to the origin point? But we haven't realised because we've been here for some millions of years and the event has been activated for longer than our own existence?
