String Theory
This might seem like a crazy theory, you need to know the other dimensions of String Theory and how they interact together before things start to get interesting. I'll skip the 3 known dimensions because everyone with 5 or more brain cells already knows what they are, let's focus on how fascinating and possible this could be. This is just my simplified explanation of these, I highly suggest you research this theory with an open mind. The other dimensions aside from the 3 we know of are as follows. Time is the 4th dimension The Probability of other Universes existing is the 5th dimension All possible Universes branch out from the same starting point. For example if our universe came from the big bang then all other universes were created under the same conditions.This is the 6th dimension. All possible spectrums of Universes with different start conditions is the 7th dimension. Meaning there's a universe where Gravity repells instead of attracts, a Universe where fire is c
