Also, as a proof of the confusion (and corruption) in physics, the fact
that the 2024 Nobel Prize in Physics was awarded to two pioneers in
neural networks (the foundation of OpenAI, ChatGPT, etc.) BECAUSE it
used tools of STATISTICAL PHYSICS, among many other branches, in their
work.

Only the cutting edge of fundamental particle physics appears to be
"dead" as you put it. The "easy" problems were all resolved by the
middle of the last century and in subsequent years have been amply
verified by experiment. This includes parts of physics that you
despise like SR, GR and QED. Verified, re-verified and re-verified.
No grand conspiracy, just good science, despite your incorrect gut
feelings.

For the past four decades, theoreticians working in fundamental

is incapable of validating or definitively rejecting their theories

Hossenfelder describes.

Fundamental particle physics, however, is only a small part of the
entire field termed "Physics". Huge areas are vibrant with astounding
progress. Simply browse through any issue of Physics World or Physics
Today. The 2024 Nobel Prize was awarded to researchers in a subfield
of physics that didn't even exist four decades ago, which today
embodies a close collaboration between theory and experimental science
and technology, precisely the sort of collaboration which leads to
amazing progress in the field.

 The inflationary epoch and cosmological models have been
pretty roundly paint-canned by JWST, though of course
the WMAP finding infrared and 2MASS establishing blueshift
for at least several decades already built "Hubble tension".
 Heh, giving physics prizes for Hopfield or Kohonen or the
various contributors into neural nets, and calling that
"experimental" physics, has that they're experimenting
on their sims I suppose - heh.
 The prevalent "apparent dark matter" and "apparent dark energy"
means usual theory today is, ..., "wrong".
 The, "apparent super-luminal", is another sort of example,
that thankfully the sky survey and its huge variety of
apparent configurations and energies of experiment,
makes it so that anybody invoking "apparent illusions"
or "apparent missing things" is invoking "non-science",
and furthermore SR is local and there are Aspect/Bell
type experiments, Lense-Thirring appears real, and
otherwise the coterie of coat-tailing paper-hangers
getting a bigger mainframe is about as useful as
giving a janitor a mechanical car-wash.
 I.e., some have that as "not doing physics" any-more.
 "Were you able to reproduce their results?"
"Well yeah we downloaded the code they gave
and it runs just fine."

Since big-bang theory must be wrong, there is actually no need for inflation periods.
The 'real deal' is usually upsetting for too many physicists, that most just 'duck aand cover', once they hear about it.
The main point is: 'to geometricise time'.
If we assume a certain spacetime-configuration as universally valid, where we have local time and in the adjecent space a (also local) 'hypersheet of the present', than we would expect some kind of 'light-cone configuartion' everywhere and on all scales.
(This is really difficult to understand, but fortunately my 'book' can help:
https://docs.google.com/presentation/d/1Ur3_giuk2l439fxUa8QHX4wTDxBEaM6lOlgVUa0cFU4/edit?usp=sharing )
Now imagine the so called 'big-bang' is actually a transition, where time passes through the hypersheet of the present from past to future on a very large scale.
But we can have smaller bangs, too, which are, what we usually call 'white holes'. These are the time reverted versions of what we call 'black hole'.
This is summed over all scales and builds actually kind of a fractal and that is how the universe apparently functions.
