>>11079339The MWI is simply a joke if you consider what it aims to achieve and how it achieves. The basic premise of MWI, if it is to be believed is that there were an infinite number of universes all along. There's no creation of infinite universes, it was already there. And this infinity is stupendously larger than anything else.
Now where it falls short is at the moment of creation. If we are to also believe in the big bang theory, then quantum mechanics as we know it probably wasn't as it is back then and different laws of physics might have been at play. So you cannot trust MWI simply for the fact that it requires the current known QM laws to hold true at the instant of creation.
