Like.
The interesting thing about intuition is that it is not fixed. Intuition is built on experience. At this point I have enough experience... -

That is certainly a possibility. It is under investigation. However, even if it turns out to be true, relativity and spacetime...

This source does not meet the PF standards. So we can certainly discuss your questions, but we will not be relying on or discussing the...

PeterDonis replied to the thread High School Einstein equations don't work at large scale?.More precisely, if we just use the matter we can actually see as the source in the Einstein Field Equation, the model does not match the...

PeterDonis reacted to Lord Jestocost's post in the thread Undergrad Spatial separation of entangled particles implies physical separability? with Like.
“For this purpose let us suppose that we have two systems, ##I## and ##II##, which we permit to interact from the time ##t=0## to...

PeterDonis reacted to Matterwave's post in the thread Undergrad Spatial separation of entangled particles implies physical separability? with Like.
EPR made an implicit assumption in their argument that indeed you can stop the two particles from interacting with each other...

Not for the EPR state. It is still an entangled state and not a product state. When EPR says (something like) "after T, the two...

PeterDonis reacted to Demystifier's post in the thread Graduate Entanglement swapping and Bohmian mechanics with Like.
It seems to me that you fail to grasp the notion of a Hilbert space at a sufficiently abstract level. To understand it properly you have...

PeterDonis replied to the thread Graduate Entanglement swapping and Bohmian mechanics.To follow up more on this: the Ma paper [1] says (bottom of p. 4): It's unfortunate, at least for our discussion here :wink:, that...

I am studying, will respond tomorrow. Thanks! -DrC

PeterDonis replied to the thread Undergrad Spatial separation of entangled particles implies physical separability?.You do get 2, but you can't split the state up into a product of two states each with a value 1 for the number operator. That's what it...

PeterDonis replied to the thread Graduate Entanglement swapping and Bohmian mechanics.I will note, btw, that although I've pitched this in terms of Bohmian mechanics, what I posted in that post only involves the wave...

PeterDonis replied to the thread Graduate Entanglement swapping and Bohmian mechanics.I have a suggested Bohmian model of the DCES experiment. I'll sketch it for now, and possibly follow up with more detail in later posts...

PeterDonis replied to the thread Graduate Deviations from classical action and D’alembert's principle, why is D’alembert's principle not applicable to QM?.That's correct.

PeterDonis replied to the thread Graduate Deviations from classical action and D’alembert's principle, why is D’alembert's principle not applicable to QM?.If you're using an interpretation of QM that includes collapse, yes. Paths aren't wave functions, and even in collapse interpretations...
