I read it. First, never trust Italians. Think pinocchio.

Second, the thought experiment is asymmetric if the article is correct in its explanation because wigners friend makes a measurement on a system of photons but wigner himself measures a super position of his friends measurement and the photons.

I guarantee that it is a clear ordering of events; if you make a measurement collapsing the wave function, then I will see the same collapsed state provided o know you measured first.

In other words, the reality was different for both people before the measurement took place.

"Being" is not the same as "becoming". Since you are "becoming" something else, you obviously aren't complete and cannot "be" anything particular. Reality is subjective because nothing independent is "real", only the sum and principle of everything is "real" and cannot be comprehended.

It doesn't, and no one is saying that it does. Metaphysics is just the study of the nature of reality. Unsurprisingly, such a study is quite unscientific, because there is just so much we don't know about reality. What these people did was just expand the very very small area of this study that IS scientific by one small step.

Replace "we" with the person writing the article/original paper and you're correct.

There's no reason a measurement of 1 photon should collapse the whole wavefunction.

If you have 2 entangled photons, measuring the spin of one also measures the spin of the other, due to conservation of quantum number. If one's up the other's down (assuming they came from a spin 0 state).

However, if you have 6 entangled photons, measuring one says very little about the other 5. An individual of the 5 could still be up or down, now it's just 60/40 instead of 50/50.

QM isn't magic. Wavefunction collapse is well understood logically, except by this guy I guess.

An iron can become a magnet with absolutely no quantitative difference. What's your point? Quality over quantity is the point.

Prove your real first. I won't reify an absence.

Form vs matter (material). "Matter is formed" not, "matter produces forms". The forms are higher and not reifiable because they have no physical existence. They are also non-specific, there is no "most true and real form", because it's a conjugate of matter/material.

It’s not really an absolute, more like a superposition of absolutes.

There is no objective truth, but also all subjective realities are simultaneously and irreconcilably true. Post-modernist thought is not proposing the existence of an absolute rule that there is no absolute, but rather applying the probabilistic nature of the quantum field to our lived experience. Quantum science doesn’t allow for objective truth, because all possible realities/outcomes/perspectives exist simultaneously, and collapse repeatedly into different outcomes based on probability

How "real" is an "effect"? Things can be hot and cold, does that make "hot" and "cold" exist as something that does something? No. Something causes something else to obtain the quality of "hotness" or "coldness".

How cold/hot are you right now? How hot/cold will you be tomorrow? How old and decayed are you now? In 40 years? Does that mean you'll be "less real", "more real" or the exact same realness in 40 years? Obviously not the latter, and the former isn't exactly an absolute now is it? Neither are you. You don't exist because you aren't complete.
Bask in the joy of being able to change, for an everlasting being or deity certainly wouldn't nor could not. It wouldn't even think, because it would be all knowing. The truest "absolute".

>>10460858
And the truest absolute is the absolute itself and is therefore self-evident to itself. It cannot be known for it is not self-evident to us as mere parts of that order, like how an organ cannot perform all the tasks of the body. It's a locution more than a self-contradiction, like saying "we with our limited potential will never know the real truth" or "the truth evades us no matter how hard we search".
