@The_Ballistic_Baron the multiverse is in our universe because the exact amount of space in space is infinite, and because time is slower without gravity it takes us so long just to reach the end of our solar system, it would take us over twenty generations to get to the closet galaxy that is not our and with other galaxies there are other solar systems and with other solar systems there are other earths, and humanity would've evolved into something like ours because its all a mirror image, but there will be slight changes, for example i could be named harley like my parents had planned instead of jamie, i could be blond, my dad might not be fat, idk its all a certain possibility though because space is infinite there is no end, meaning more earths more differences, more possibilities, more choices and there you go a brief explanation of the multiverse
