First Things First: The Physics of Causality
Why do we remember the past and not the future? Untangling the connections between cause and effect, choice, and entropy.

Can Time Be Saved From Physics?
Philosophers, physicists and neuroscientists discuss how our sense of time’s flow might arise through our interactions with external stimuli—despite suggestions from Einstein's relativity that our perception of the passage of time is an illusion.

Thermo-Demonics
A devilish new framework of thermodynamics that focuses on how we observe information could help illuminate our understanding of probability and rewrite quantum theory.

Gravity's Residue
An unusual approach to unifying the laws of physics could solve Hawking's black-hole information paradox—and its predicted gravitational "memory effect" could be picked up by LIGO.

Could Mind Forge the Universe?
Objective reality, and the laws of physics themselves, emerge from our observations, according to a new framework that turns what we think of as fundamental on its head.

Real measurements of what? Bell's theorem is a mathematical theorem, not a physical theory; it demands that "measurements" be made on mathematically-identical pairs of particles. But there is no evidence that such idealized things "really" exist, in the "real" world. Hence, none are likely to ever be measured. Indeed, the "real" measurements, made in "real" Bell tests, amount to nothing more than a "reduction to an absurdity" demonstration of the falsity of the theorem's identical-particle...


I like how stubbornly you stick to your argument...but you should at least do a real measurement to show your point and not calculate a set of measurements with some assumed Shannon error. At least then we would be arguing about measurements and not about calculated measurements...


In a very perverse sort of way, you are correct that quantum phase noise matters: For example, many of the "measurements" performed in Bell-tests yield the completely wrong result - declaring the measured entity to be "up" when it was actually "down" etc. This has been demonstrated to happen, due to the combination of having the detector's "phase angle" being misaligned with that of the "phase angle" of the entity being measured, and the noise intrinsic to that entity.

It has also been...
