Fra replied to the thread Undergrad Strings 2025 Conference: Insights, Criticisms, and Key Highlights.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... -

Haha.
After having read Brian Greene's The Elegant Universe I have been a bit enthusiastic, but unfortunately ... -
Fra replied to the thread Graduate Understanding Barandes' microscopic theory of causality.It also offers a unique alternative interpretation to the ontological status of dynamical law and thus causality. Instead of seeing...

Like.
The interpretation would be the conceptualization of a quantum system as a system with a definite classical configuration, evolving... -
Fra reacted to Morbert's post in the thread Graduate Understanding Barandes' microscopic theory of causality with Like.
It offers a reformulation that might prove to be useful beyond foundational/conceptual questions, and there would be no problem in...

Fra replied to the thread Graduate How to fix Relativistic QM so it's consistent?.Thanks for the confirmation, it seems to be where it was before as expected, but wasnt sure as I dont regularly follow strings. 500...

If you're asking about vacuum selection, no one's even thinking about it. The focus in string phenomenology is still just to find vacua...

Fra replied to the thread Graduate How to fix Relativistic QM so it's consistent?.The stage is wobbly yes, but I thikn even the actors are wobbly. So one must not be mistake to think that one can reconstruct emergent...

Fra replied to the thread Graduate How to fix Relativistic QM so it's consistent?.My simply issue with the "geometrical picture" is that I find it much more easy to understand the selection and emergence of structure...

@Fredrik your 'inferencial' view is really cool. I think we are looking at the same fundamental problem from two complementary...

Fra replied to the thread Graduate How to fix Relativistic QM so it's consistent?.I think the OP means RQM=RelativisticQM, not RQM=Rovellis RelationalQM, are you talking anout the same thing? IMO, from perspective of...

Fra reacted to renormalize's post in the thread Graduate How to fix Relativistic QM so it's consistent? with Like.
The following is taken from Bjorken and Drell, Relativistic Quantum Mechanics (1964), pp. 5-6: So the problem with the Klein-Gordon...

Fra replied to the thread Undergrad Question about discussions around quantum interpretations.I would say it rather makes the concept of objective probability less plausible as fundamental in a theory or interpretation where you...

Fra reacted to Morbert's post in the thread Undergrad Question about discussions around quantum interpretations with Like.
No. The operationalis/instrumentalist account is probabilistic and has no objective collapse. Consistent histories is probabilistic and...

Fra replied to the thread Undergrad Infinite number of spatial dimensions (maybe also time dimensions).I would want it to be computable for any given confidence level, but a given "computer". So if you imagine an embedding of inifite...
