Title: Physics as magic ...

Non-locality, entanglement and "the measurement problem" of QM.  That space/time isn't fundamental.

As per the Fundamental Fysics Group of the hippie 60s, is right (and per a previous post I made here) is an illusion (as per Plato's Cave).

Still woo woo in the world, it isn't Newtonian or even Einsteinian.

More on the non-locality of reality ... with revenge of Schroedinger's Cat

I don't care what theory says.  The cat is dead or it is alive and Schrödinger agrees.  He postulated it as a falsification of an argument.

All arguments are false.  They are the hobgoblins of autistic smart-ass teenagers.

An even better film that covers the same "time as illusion" that I posted in an Introduction thread.

If we don't even know what time is, then we don't know anything.  We just posture our ignorance.

So what is time?  Whatever it is, per Schroedinger's Cat, it doesn't exist without people (or other sentients).

The very first speaker ... time is defined thru circular reasoning ... aka it is unreliable.

Real physicists discussing the "measurement problem" vs "quantum interpretive framework"

One being of course the "many worlds" interpretation, which then is manifested directly in string theory.

The alternatives talked about are Boehm, Many Worlds, Spontaneous Collapse & Qbism.  I am an Qbist.  Boehm involves hidden variables.  Many Worlds is path integral, that reality covers every possible alternative simultaneously (what measurement is is taking the sum of the paths).  Spontaneous Collapse involves a "domino theory of collapse" so that decoherence happens realistically, without an external observer.  Qbism admits that quantum probabilities are Beysian ... you can't treat the probabilities as absolute, but that they are always relative to an observer.  Qbism and the other two just interpret the regular Schroedinger equation, only Spontaneous Collapse involves new physical prediction.
