Are there past or future universes?

Answer 1

According to Einstein (although it sounds a bit far fetched and plain out 'weird' this Universe is constantly doubling into new universes every single millisecond, meaning that every new universe is therefore NEW and there for on the day of initial coming into creation. Each Universe (says Einstein) is identical and their occurances are identical, and everything that happens in one Universe will happen in the other (but they cannot effect each other).

That's where Time Travel comes into play... Einstein say the Universe was created (not saying how) and a millisecond later a new Universe was born, 1 millisecond behind the first. Now, he doesn't say weather every universe splits every millisecond, he just this one. So, if we want to get ten millisecond into the past, we have to go to Universe number ten. In that sense, we cannot go to the future because this universe is the furthest yet. The future (says I) doesn't exist. Also, this removes the chances of time paradoxes (the act of changing the present by doing something in the past and all). If you somehow enter a different Universe an kill your dad before you were born, THAT Universe's future is changed and different from this one's.

However Einstein no sense in his explanation of how to get to an alternate or parallel Universe (something about copying every detail of yourself and this disintegrating and then passing through a foam cube or something and being re created as a replication of your in a different Universe.

Answer 2

There is no empirical evidence to suggest the existence of past or future universes beyond our current one in the realm of physics. The notion of parallel or alternate universes is theoretical and not yet experimentally proven.
