IMHO, one factor here about the the timescales of the difference proceses we talk about. Timescale of interactions; that are judged from a different perspectives. If the set of perspectives is well defined, we have the first part of Rovellis statement, and an equivalence class that allows to...

I get some flashbacks here from previous discussions. My take on the RQM relevance, based on analyzing rovelli and his various rqm writings long time ago is this... The ambition of RQM is conceptually sound as it embraces not only the contextuality of observations, he also explicitly embraces...

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 (not brains or human), might self-evolve, perhaps loosely like Baranders stochastic process from the perspective of a local system.. this stochastic process might...

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 I dont see that prejudices about existence of something with particular structure is required to interact. An agent/observer could conceptaully simply interact...

There are lots of books, i havent seen those the one I have is Itzykson & Zuber not sure how they differ, but thats a textbook presenting lots of techniques and foundations. In that perspective 500 pages isnt alot. Any text book in any similar topica are always hundres of pages. For some strange...

Yes but this logic presumes an interpretation where the "quantum state" is a property of the observed system. The problem goes away if it refers to the the state of the observers knowledge/expectation or relative to something. Like in copenhagen or qbism or possibly rovellis RQM. The state can...

Einstein also said "Everything should be made as simple as possible, but not simpler" Exactly how simple can somethig complex get? But 500 pages seems like a stretch. /Fredrik

The question is how far to take this. MY thinkking is that abandoning the dS vaccum, although it can be seen as technical construct, really is the first step in relaxing the notion of global observer equivalence. So I can help contemplating what completing this step implies - in particualr for...

I thought I would start a thread, as as spinoff to perhaps highlight and contemplate of that the ideas in the paper mitchell porter pointed to means. I just started to sniff it.. and wrote in the other thread "How to fix Relativistic QM so it's consistent?" Indeed fixing relativity and how to...

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 conceptualy summary (setting aside the rich string-technical details) attempt. Unless I misinterpret this (then please correct me), it seems the paper suggest the insight...

for example Hawking and others https://www.thoughtco.com/what-is-model-dependent-realism-2699404 I gets cumbersone to provide a reference to every scentences. I dont feel that Im proposing something crazy in anway, I feel its within the realm of normal discussions. About the next post, the...

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 any observational of inferential context. But I never even use that definition anywhere because i don't know what it means! and even less know how to define...

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 perspective, naturally suggests different starting points. If one considers and ABM, then the agents state, that might reflect its understanding of the...

I refer the the general modelling categorical approaches - not specific theories. Though there aren't alot of "general theorems" of correspondences between them, perhaps because expcet complexity there is no universally fixed definition of an "agent", except it has some autonomy as opposed to...

I have been busy with non-physics stuff lately so i am lagging follow up. But I just stumbled on that funny tombstone. I must say that - even if I find the foundational ansatz of string theory (ie replace point particles with strings and see what happens) is not conceptually appealing as it's...
