Fra replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.IMHO, one factor here about the the timescales of the difference proceses we talk about. Timescale of interactions; that are judged... -
Fra replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.I get some flashbacks here from previous discussions. My take on the RQM relevance, based on analyzing rovelli and his various rqm...

Fra replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.It wasn't what i had in mind. There are no brains. I entertain a more holographic picture where the microstate of the agent/observer...

Fra replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.My main point was just a conceptual comment to "I don't see what it means for something that doesn't exist to interact" suggesting that...

Fra replied to the thread Undergrad One does not “prove” the basic principles of Quantum Mechanics.Yes but this logic presumes an interpretation where the "quantum state" is a property of the observed system. The problem goes away if...

Fra replied to the thread Graduate Dasgupta et al., What is the alternative to a unique dS vacua?.Einstein also said "Everything should be made as simple as possible, but not simpler" Exactly how simple can somethig complex get? But...

Fra replied to the thread Graduate Dasgupta et al., What is the alternative to a unique dS vacua?.The question is how far to take this. MY thinkking is that abandoning the dS vaccum, although it can be seen as technical construct...

Like.
It turns out that the 500-page paper had a forerunner in 2000 that's just 100 pages, so it might be easier to read. :-) "de Sitter... -
Fra posted the thread Graduate Dasgupta et al., What is the alternative to a unique dS vacua? in Beyond the Standard Models.I thought I would start a thread, as as spinoff to perhaps highlight and contemplate of that the ideas in the paper mitchell porter...

Fra replied to the thread Graduate How to fix Relativistic QM so it's consistent?.Huge paper, I havent ready it through fully but skimmed parts of it it seems to me, to be a step in the right direction. One...

Fra replied to the thread Undergrad Strings 2025 Conference: Insights, Criticisms, and Key Highlights.Ah I see. I share your objection if if we talk about metaphysical realism! You are right of course. ie what just exists independent of...

Fra replied to the thread Undergrad Strings 2025 Conference: Insights, Criticisms, and Key Highlights.Maybe it could be interpreted so that the map is always right. That wasn't what i meant. What i mean was just the different modelling...
