IMHO, we know little, and the current particle physics and quantum mechanics models will not hold up. I love the science, but feel strongly that what should come from all of this is humility. We have no idea why gravity exists, and how it works. We can say things like objects of mass attract each other, but why is that? We can say that chemical reactions that result in a lower energy state are favored, but why is that? Lots more to know - obviously..
That said, Epstein didn’t kill himself..
Schrödinger's cat may have. Not sure.
According to quantum theory, quantum systems can exist at the same time in various states defined by probabilities. You wont know which unique state the system is in until you look , at which time the probability function collapses into a single state that you see.
If Jeffrey Epstein is part of a quantum system, he could exist in the state of death, having killed himself , in the state of death, having been murdered, or in the state of being alive in some some witness protection program with a dead patsys body having been substituted . Unfortunately we may never know because when they looked, the independent expert coroner said they screwed everything up.. The Epstein quantum system is destroyed and there are no do-overs allowed in quantum mechanics.
I am not a physicist, but I do read FR and QAnon.
And neither did his banker.
