Ppines-demon replied to the thread Graduate Two equivalent statements of time reversal symmetric Hamiltonian.For that your Hamiltonian has to be diagonal in ##q##. Also you are assuming properties of ##\Theta## if not I don't get how are you...

Ppines-demon replied to the thread Graduate Two equivalent statements of time reversal symmetric Hamiltonian.Sorry this gets confusing because we mix various stuff in second quantization, your ##H## is in some basis, let me use hats for...

Ppines-demon replied to the thread Graduate Two equivalent statements of time reversal symmetric Hamiltonian.Be careful, what is the argument? If you write ##H(t)## or ##H(\mathbf r)## it is not the same as ##H(\mathbf k)## (##\mathbf k## being...

Ppines-demon replied to the thread Undergrad Before the Big Bang.I do not know if this has been brought out. There is this theory of Janus universes (as in Janus the god with two heads). Where...

Ppines-demon replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).To be clear, I agree with you.

Ppines-demon replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).I still do not know what this is all about. All his proofs are.

I think you need to justify this statement with some kind of reference to the literature. AFAIK nobody has ever tried to defend this... -
Ppines-demon replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).I do not know what this has to do with anything I said. Nevertheless, it is important to point out that Bell clarified this nonlocality...

Ppines-demon replied to the thread Undergrad Valid local explanation of Bell violations? (Pegg et al., 1999; 2008).It is, it is retrocausality. You might say it is "local" if you wish but you are still breaking causality which seems as or more...

Again, I'm not sure why. Consider an obvious "hidden variable" interpretation of the retrodiction: measuring H for the first photon...
