Multiverses are ascientific. And they are getting excessive attention because it seems 'cool' and scientists are all too happy to romanticize it for the attention. But we need to stop pushing it so much. It is akin to a religious belief, which is fine if you want to hold that belief, but don't paint it as scientific or in line with our current understanding. It is an extreme application of math (quantum wave function) to reality without the ability to test and validate, and zero evidence for it within our current scientific understanding.
