Yeah. That wasn't clear. Let me back up a bit. Let’s say I plot out 2 entangled photons on a Minkowski diagram. Their paths are right on the edge of the light cone at 45 degrees. I hope that makes sense. And let’s say I set the angle of my 2 detectors so that I can assume the results will...

This question is about experiments involving entangled electrons or any other fermion for that matter. I’ll get to that in a sec. I’ve been interested in understanding interpretations that have retrocausality. (TIQM by Cramer, Wheeler–Feynman absorber, time symmetric by Price) It’s easy to...

I'm still working my way through RUTA's insights article. Looks like no shortcuts for me. I'll add @rkastner to my reading list. Thanks!

I have a few questions about interpretations that use retrocausality. I only know of 2. 1. TIQM - Transactional Interpretation of QM by John Cramer 1986 https://en.wikipedia.org/wiki/Transactional_interpretation 2. TSQM - Time Symmetric QM by Huw Price...

Atty: That page you linked to says “TIQM is explicitly non-local.” If the confirmation wave travels back to the emitter along the same path as the offer wave, then it stays within the future light cone of the emission event. It also stays within the past light cone of the measurement event. So...

Wow. Thanks Atyy. That was quick. So the pilot-wave interpretation doesn't include anything going backwards in time. Right?

It’s easy enough to find the interpretations that break counterfactual definiteness in order to maintain locality. But I’m not sure how to find the ones with something (perhaps information) moving backwards through time. The reason I ask is I’ve always had trouble with the idea that a...

That's what I love about PF. Thanks guys. I did found some good stuff on "viscous dissipation"

I always thought of a reentry vehicle compressing the air in front of it. And that would cause a lot of heat kind of like filling my tires. But I keep hearing friction even from NASA heat shield experts. OK, I guess maybe 10% of the heat is friction. I always assumed they said that to make the...

I’ll take a crack at it. I’m not great with GR. But SR I got. GR covers the special case of SR. So, yeah, you should get the same answer. But I don’t think it’s the way you’re thinking. It’s not the acceleration. The twin paradox can be demonstrated without any acceleration if you use a third...

Cool. Thanks. Copenhagen - Copenhagen is local? I didn't know that. many worlds - Many worlds is local? I didn't know that either. superdeterminism - Sounds crazy but I'll read this http://en.wikipedia.org/wiki/Superdeterminism backward causation - I assume the causally symmetric Bohm...

By Bell’s theorem, an interpretation of QM must break either locality or causality. Linked below is the only interpretation I know of that chooses to maintain locality. (I don't know many.) Do you know of any others? CAUSALLY SYMMETRIC BOHM MODEL...

Cool! I did not know that. It needs a better name. What other interpretations are "causally symmetric"?

Bohmain: Is that the pilot wave theory with the hidden variable going back in time along the path of the particle? I'm kinda partial to that interpretation. I didn't know it could have a preferred frame. I like it because I think it has a nice solution to that problem. I seems to be nicely...

Got it. Makes sense now. Thanks. The word "instantaneous" keeps making me think there's a preferred frame. Instantaneous for one frame is backward in time for some other. I just can't get around to thinking that QM makes anything happen instantaneously. To me "instantaneous" just means at the...
