Is it possible to travel between parallel universes?

If you are an advocate of a multiple big bang multiverse, then that would mean that leaving our universe to travel to another would be just as impossible as travelling back to the time before the big bang that resulted in our universe even happened. No matter—you’ve worn them both, in two separate parallel universes.

What if our universe collided with another universe?

If the universe that we inhabit had long ago collided with another universe, the crash would have left an imprint on the cosmic microwave background (CMB), the faint afterglow from the Big Bang. And if physicists could detect such a signature, it would provide a window into the multiverse.

Do we constantly flow from one parallel universe to another?

However, we do constantly flow effortlessly from one parallel universe to another. Every time you choose one option in life over another, you split off and move into a different universe. (Another “you” will still exist in that previous universe, by the way, but your focus won’t be there so you will no longer experience it as your main reality.

Are We always aware of the different universes?

We just assume there is only one universe, one reality, so we’re not always aware that we’ve changed universes. However, we do constantly flow effortlessly from one parallel universe to another. Every time you choose one option in life over another, you split off and move into a different universe.

Are there two universes?

The simplest explanation for the phenomenon is that at the moment of the Big Bang 13.8 billion years ago, two universes were formed — ours and one that from our perspective is running in reverse with time going backward. Of course, if there are any inhabitants of a possible parallel universe, they’d consider us the backward ones.

How often do we shift into different universes?

We actually shift into different universes all the time. We just assume there is only one universe, one reality, so we’re not always aware that we’ve changed universes. However, we do constantly flow effortlessly from one parallel universe to another.
