PeterDonis replied to the thread Graduate Could there be a "Communication Theorem" instead of a "No-Communication Theorem" in quantum entanglement?.It's a known conjecture, though speculative: https://en.wikipedia.org/wiki/ER_%3D_EPR The OP is simply mistaken about what is actually... -
PeterDonis replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.Yes, that's true, although the way it isn't is somewhat counterintuitive. Spacelike separated measurements can still be correlated... -
PeterDonis replied to the thread Graduate Could there be a "Communication Theorem" instead of a "No-Communication Theorem" in quantum entanglement?.No, that's not what they require. They require what is called "exotic matter", i.e., stuff that violates the energy conditions that... -
PeterDonis replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.This might be a bit misleading. Bell did not make any specifically relativistic assumptions when deriving his inequalities, so Bell... -
PeterDonis replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.I think it's true of any physical theory. -
PeterDonis replied to the thread Undergrad Strings 2025 Conference: Insights, Criticisms, and Key Highlights.No, this is not good advice, because it is tantamount to saying to give personal opinions instead of discussing the actual physics... -
PeterDonis replied to the thread Undergrad Strings 2025 Conference: Insights, Criticisms, and Key Highlights.Which says that this is a philosophical concept, not a physics concept. So it's off topic here. Nobody asked you to. The problem was... -
PeterDonis replied to the thread Undergrad Strings 2025 Conference: Insights, Criticisms, and Key Highlights.Comes from where? Once more, discussion needs to be based on something that's in the literature, not just your personal opinion. Same... -
PeterDonis replied to the thread Undergrad Strings 2025 Conference: Insights, Criticisms, and Key Highlights.I wasn't "interpreting" it at all. Again, here is what you said: I don't see any need to "interpret" this in order to think it's... -
PeterDonis replied to the thread Undergrad Strings 2025 Conference: Insights, Criticisms, and Key Highlights.This seems obviously false to me. Again, is this a viewpoint that appears in the literature? Or is it just your personal opinion? If... -
PeterDonis replied to the thread Undergrad Strings 2025 Conference: Insights, Criticisms, and Key Highlights.Can you give references for these approaches? -
PeterDonis replied to the thread High School Is it correct to state that all measurements count photons?.After moderator review, the thread will remain closed. As @FactChecker points out, the fact that the EM interaction is involved in some... -
PeterDonis replied to the thread High School Is it correct to state that all measurements count photons?.Thread closed for moderation. -
PeterDonis replied to the thread Undergrad Physical Interpretation of Frame Field.If you can Lie drag a vector field, how to Lie drag the integral curves of that vector field should be obvious. -
PeterDonis replied to the thread High School Is it correct to state that all measurements count photons?.Almost all measuring devices do not count photons. For example, you mention reading a thermometer, which requires light to see its...
