this is vaguely related to the string theory related post from a day or two ago, it's all bazinga science folks TL;DW string theory is a big thing because people that read pop science really liked it and it took a long time for physicists to come out in force and say "this is untestable garbage"
how is a multiverse any less testable than a single universe though? It seems to me there are “at least one” universes and narrowing down the “at least” part seems difficult

Theories depending on ever-more universes which cannot be observed at all by us are massively inelegant compared to ones with just our universe.
