When you have been bestowed upon with the ability to imagine, why stop at something a 100 other people can imagine too?
I have already built the premise for Parallel Universes and Multiverse.
Often, we think of them as the same. But, what if we didn’t?
What if we treated Alternate Realities and Multiple Universes as two different objects?
Say, with 7.2 billion people in the world, there happen to be around a 100 million quantum level decisions made in a day. That would mean, a 100 million Alternate realities. And then each of them having another 100 million and so on and so forth.
We shouldn’t be so arrogant as to believe that we are creating ‘Universes’. We are just creating alternate realities in our Universe.
That is completely different from the concept of Multiverse.
Schrodinger’s cat dying or living would create an Alternate Reality. Not another Universe.
Our Universe, as we know it, is 13.8 billion years old. If we hit the farthest target and assume there might have been a Big Bang almost the same number of times, we would end up with insanely huge number of Universes.
Not 13.8 billion.
Gotta factor in the 11 dimensions, possible pocket dimensions, possibility and probability of a Big Bang to have had such a huge impact that it ended up creating more than 1 Universe, etc.
Factoring in all of that, and then combing in the 4 fundamental forces we know of, the number would roughly be around:
(5.8805183E+85 + 4.398080063836)/125
Though that might just not be even anywhere near. There is no way to know until we can solve the ‘String Theory’.
P.S. We are not alone. Neither is our Universe. Nor our Alternate Realities.
