What is entanglement? Itamar Pittowsky claimed that these results brought us right to the precipice of logical contradiction--but not over. Abner Shimoney described it as a piece of "experimental metaphysics." I'm a nobody, but I think entanglement is the most interesting thing ever discovered.

Imagine a parable of two groups that set out in different directions in space toward two remote planets. Each of them is now so remote that they can each construct particle accelerators, with the entire duration of the construction projects at space-like separation to one another.
In a QFT context, we need Alice's scattering experiment to go *exactly the same way* (statistically) for all of Bob's locations x, while x ranges in a relatively-spacelike region O.

Many-Worlds has some interesting overlap with thermo/direction of time stuff. Most straightforwardly, why does branching occur towards the future and not the past? The answer to this has to be ultimately thermodynamic in nature.
But more subtley, consider this: why do yours and mine and

Since observers are macroscopic, they quickly entangle with the environment ("decoherence"), and the resulting terms in the quantum state behave like separate non-interacting worlds. How do we deal with observers in such a universe? That's where some philosophy of cosmology will come in.

something I hadn't really absorbed before is that, in quantum mechanics, free particles show their mass.
okay i need urgent help for a talk i am delivering tomorrow:
suppose you classify all the unireps of Poincare a la Wigner. how would you explain to a non-physicist audience why you identify the parameter m as mass?

damn yea i wonder what that was about. probly in good faith, tho.
As all this disgusting Epstein shit starts surfacing more and more, I hope we don't lose sight of the fact that apparently every major media outlet knew everything and instead spent their time money and energy attacking the trans community.

Phobos is slowly drifting toward Mars. Tens of millions of years from now it will crash land.

The previous discussions of particle localization were (imo) confused by a three-fold conflation on my part; namely, between:
1. What is the *description* of objects, particles, etc, when they appear to be localized? i.e., literally which state vector do they occupy at those times?
1. What is the *description* of objects, particles, etc, when they appear to be localized? i.e., literally which state vector do they occupy at those times?
Okay so I don't actually buy this.
Entanglement has complicated causality, but even so we must be sure to rule out superluminal signaling. That is, correlations between remote outcomes are fine, but there absolutely cannot be correlations between a selected action of mine and remote outcomes.

I finally internalized the obvious: my presence on earth (whatever this means vis-a-vis the QFT state) increasing (or being functionally related in any way to) the probability of a photon deflection in andromeda is *not* evidence of a causal relationship. It is an expression of entanglement.

you could say CDP is for securing the approximate idea of subsystems, CCR is for locality. different things.
the problem is that the above charge will only propogate its influence along null geodesics. whereas, in QFT, there is some chance i scatter a photon in andromeda *right now.*
