>b-b-but muh many worlds interpretationNobody seriously doing QM gives a fuck about interpretations. There's postulates and you work with them. End of story.
>b-b-but I heard Susskind/Kaku say something about multiversesThey're string theorists and it's their ultimate cope. They promised us that they'll be able to uniquely derive the Standard Model of particle physics from their string nonsense because "it just works bro". Past forward a couple decades and by the 00s it was clear that their bullshit not only had non-unique predictions, but there's a gazillion of them and they had no idea how to pick one and work out the Standard Model from it. To this day they still don't.
Long story short, the well has dried for string niggers, they need to cope somehow to get grants, so they go muh multiverse muh anthropic principle. Both unverifiable philosophical sugar to justify the failure of string theory to predict anything useful.
P.S. when a string nigger says they can derive Hawking radiation from their nonsense, just know that they're lying. They can derive it in an 11-whatever dimensional spacetime with the negative (wrong-sign) cosmological constant. They can't do it for our real world.
