There’s one interpretation of the meaning of quantum mechanics that manages to skip a lot of the unphysical weirdness of the mainstream interpretations: it's de Broglie-Bohm pilot wave theory.

The weird results of quantum experiments seem to demand weird explanations of the nature of reality. In this episode, Matt discusses de Broglie-Bohm pilot wave theory, the one interpretation of quantum mechanics that remains comfortably, stodgily physical.

What's the quantum mechanics interpretation that you prefer?
-
doesn't make sense cause once the particle is measured the wave must collapse, thus the two lines if measured instead of the interference pattern
-
Bit of a random question, but does this have any relation to quantum field theory. I only know the basics of the latter and was wondering if they were related. Will y'all be doing an episode on QFT?
-
So one question that I had throughout the course of this video was how exactly does Pilot-Wave Theory explain the different results of the Double-Slit Experiment based off of whether or not it was observed?
-
I didn't see this mentioned in the video, or asked in the comments: This formulation requires the existence of an additional object, and a pretty specific kind: the pilot wave. It's something that permeates all of space and time, has nonlocal properties, and interacts with "ordinary" particles, in that it drives them. Aren't there any objections to the fact that no experiments so far have measured an object like that? This reminds me a lot of the Ether, which had all these esoteric properties attributed to it simply because people refused to cope with the strange properties of light and EM fields, and which in the end had to be thrown away because measurements didn't show evidence for it.
-
Holy moley you cracked me up at the end there! heehee :D

I'm happy You finally came up with the carrier-waves theorie and de Broglie stuff.
You said it doesn't take in account Relativity but try this: SEE THE RELATIVISTIC EFFECTS AS A DOPLER EFFECT on the carrier-waves, relative to the point of observation ;-)
Also, we should not forgot that Relatively is an ABSTRACT THEORY, a "THEORY OF APPEARANCE" (how to interpret signals, informations which are plus or minus "old" function where do they come from in the space, NOT// "A THEORY OF THE REALITY AS IT IS IN THE PRESENT TIME"; said an other way: Relatively, looks to us, is only "A THEORY OF IMAGES OF THE REALITY", NOT// of The Reality itself. While de Broglie interpretation IS a "REALISTIC" THEORY as we would say.
But Very Thanks to put these theories under the spot :)

Easy solution... Heisenberg Compensators from USS Enterprise 😂😎
-
What books would anyone recommend on further reading about Electromagnetism, Thermodynamics, The weak and strong nuclear force's or Relativity and even Quantum Mechanics? Does anybody have any suggestions that can help me to further understand these concepts? Thanks if you have anything.
-
If pilot wave theory has instantaneous information transfer, that contradicts Einstein, doesn't it ? The information is encoded in hidden variables, but the information is still transmitted, isn't it ?
-
Quantum mechanics is a topic whose explanation goes like "cus the equation says so"with no explanation of the weird phenomena that it suggests. (for eg tunneling qm suggests electrons can pierce a infinite potential barrier but provides no explanation as to how )
-
I swear, I learn more from a couple hours watching this channel than I do from years of school. :-)
Keep up the great works!!! -
Sorry for my bad english. But i just wonder, what is 'wave'? It's sound stupid. But i mean, wave in real life from water, and it's make a surface, a wave, like sound, or in quantum mechanics, what's it look like? A particle movement in a path like wave?
Thank you for answer my question, it's seem obvious but make me unclear.

Here is what all the discussions of pilot waves seem to leave out: what is the pilot wave waving in? Does the existence of pilot waves reserect the the search for the super lumio aether?
-
lose the beard and stop waving ur hands and ur good
-
This, no.
-
can't any scientist ever consider idea of non-existing time? it's hard to understand, maybe impossible to work with, but there is nothing preventing it from being possible reality. like, you cannot prove it false.

Any thoughts on the Penrose interpretation of QM? (https://en.wikipedia.org/wiki/Penrose_interpretation_of_Quantum_Theory)
