You Didn't Ask But Anyway: Wherein a bunch of physicists describe what is mostly the discontinuity between #QuantumMechanics and #Relativity. If I'd been there I'd hammered away at two elements- Time and scaling.We have to look at the primitives that get us to the #StandardModel. If it's not #QM or #Relativity...and it's not new physics, then what ? Whatever it is is gonna be embarrassing...because it's been there the whole #Time

...obviously the physics landscape in 2024 is not simplified if you followed things thru 2023. Probabilities still go to the #Astros for progress, they have the advantage wrt instrumentation , data...and particle accelerators bigger than anything on Earth. The other side of that is those things tend to misbehave in ways that frequently suggest we don't t know what we think we know.So much for clearing things up
...now if we were to build an instrument sensitive enough to see so far into the cosmic past that we were actually able to see nonlinearities in time...possible anomalies of an inflationary regime...how long would it take for us to understand what we were looking at ?
Here's another discussion on #QM #Relativity and #QuantumGravity, including Erik Verlinde working the string theory side.

It's worth noting that missing from both these discussions is the perspective from particle physics -the links between mass and massless regimes, the force carriers, unification energies and the primary interactions between #Mass and #Spacetime. Maybe somebody missed a flight or something

...also hats of to #SabineHossenfelder for an operational perspective that made these discussions a bit easier on non physics people in the audience but then ending with the Dim 4 manifold
