There are no quantum states communication FTL. There is even a theorem about that.
That would involve mixed states (for communication) and if you have one eigenvalue (like position) your momentum uncertainty can be FTL but in the wash it all evens out.
Regarding entanglement, I know, no communication FTL. C'mon give me that much?
Metaphysical prejudices, mainly. He believed nature must be like that, and could not accept that it was not as he thought.
and hidden variables
No, lol. Metaphysics? Like someone once said, do not concern too much about that, just follow the math. Our brains are the product of naturalistic processes geared towards survival, not truth, and are totally unreliable when it comes to understand things that are not needed to survive. Like the ontology of a quantum wave.
Disagree.
Our brains are incredibly reliable when it comes to understanding things not needed to survive.
Proof - all math beyond basic addition/subtraction, quantum mechanics, relativity (2), quantum field theory, QED and so forth, astrophysics, cosmology, philosophy, etc..
In Maxwell's day what do you think metaphysics was? It was relativity, quantum physics (and a lot of fake stuff).
We might be at the limit of understanding but I doubt it.
However, the ontology of a quantum wave IS a reality. We're not talking religion here. Waves have some reality, something is there. It isn't "nothing". It's also not just "emergent behavior" of spacetime because it would show up in a quantization of sace-time (well we don't have that yet). But say we quantize gravity and there is still no explanation for the existence of the wave function. It's still embedded in reality and the standard model doesn't get to it.
A wave function is actually the ultimate reality and we don't know what it's made of or if it's just a mathematical entity?
If you are smaller than your wave you exist as a superposition of states but if bigger than it you collapse yourself? This isn't a problem of understanding it's a problem of figuring out what the heck is going on. It's looking like more layers are going to be needed to reality or to "the physical".
You do not need metaphysics, you need brains that understand that. The physical and natural character of our brains does not allow that.
We are not at the end of our ability to understand the universe. Not likely.
There is a science that we can understand behind some of these mysteries of physics.
Why would things change now?
Yes, I did not use shut up, but that is the meaning. And forget all that new age nonsense of consciousness affecting reality. They just want to make a buck by selling existing pseudo metaphysical or dualistic realities to the gullible starving for something more than the physical.
Well I'm not talking about "The Secret" here. There is an interesting push-back from all that "consciousness creates reality, quantum physics proves it" BS.
Now scholarship can't even talk about the fact that there are some mysterious properties in quantum mechanics.
Neil DeGrass Tyson has repeatedly gone on talk shows and said "there is no mystery to the wave collapse, measurement interferes with the wave and it collapses".
As if he's talking about a classical object.
That is not true. In the double quantum eraser you measure the "which way" of the photon and it collapses the wave. If you destroy the information before the photon hits the detector it will go back to being a wave.
Details of the experiment here:
Delayed Choice Quantum Eraser
In a simple double slit if you use a detector you will collapse the wave but if you use the detector but destroy the information it will not collapse
"
3. Record the measurements at the slits, but then erase it before analyzing the results at the back wall. Suppose we take our modified double slit set up -- with electron detectors at the slits -- and still leave everything intact. And we will still keep the electron detectors at the slits turned on, so that they will be doing whatever they do to detect electrons at the slits. And we will record the count at the slits, so that we will be able to obtain the results. But, we will erase the data obtained from the electron detectors at the slits before we analyze the data from the back wall.
The result upon analysis: an interference pattern at the back wall.
The Reality Program
No one knows what that means. But now it's become like a religious belief at a Catholic/Jewish wedding - It's better to just not speak of it so everyone gets along?
It's why I mentioned Quantum Enigma because they at least went over the evidence. They admitted the question gets raised.
Even a bacterium can collapse a wave, so to speak. There are much more compelling interpretations that do not introduce ad hoc mechanisms absent in the theory. With the bonus of making it deterministic again, by just redefining what we mean with Universe. I am not sure Einstein would have appreciated, but nevertheless....no dice, anymore.
Currently there are Copenhagen, Many-Worlds, and like 8 others.
The fact that the wave collapses or doesn't or even switches when information is available or not does make it seem like something is going on with consciousness. I know we can't say.
If you tried to determine if a bacterium could collapse a wave it would be a situation where the information about the particle was available to you also. So it would collapse.
But isn't it weird that you can do a double eraser or have a detector run the information through a scrambler and then it will allow a collapse the wave? Why would a wave care about information in a detector or information that has been destroyed after it passes the detector?
I'm saying that with all these mysteries that there is more layers to reality and that we will understand it.
I'm not getting paid by scholarship so I can say or speculate whatever I want and I will experience zero pay cuts.
