And since the reality does fit it  - The dishonest,

"IMPROPER!!!  NONSTANDARD!!!!"

Here's one, "you know why the Lense-Thirring and
the v_e are about the same?" "Terrestrially
they can't tell apart the equivalence principle
of the forces the gravitational and the acceleration".
Or, GPS, blocks, "the receivers are given a particularly
precise frequency and here's is why", and here's is why
is there's mass-produced about a billion of them and
it's much less complicated to steer the satellites
than re-run the geodetic survey every day.
"Why do GPS satellites both have clocks and receive
timing information from the ground station?"
Because space-time in space-contraction varies,
sort of like a geodetic survey, yet it's the
survey of the ephemeris, not just providing
triangulations for Earthlings to count their
10,000 steps to the burrito palace, but feeding
back ephemeris to keep the 29+ variables futzed
of the "Parameterized Post-Newtonian" up-to-date.
So it's sort of a false dichotomy about the GR
and the GPS because while it _is_ in accords
with an interpretation of GR like later Einstein's
with space contraction in effect, it _isn't_
much giving the Parameterized Post-Newtonian
ephemeris of Earth, and its surrounds,
"global positioning".
Then, Maciej comes across as a flake, yet,
most are sort of know-nothings, or, you know,
"coffee-table book physics of the last century".
Everybody's real proud of JWST, it's totally paint-canned
inflationary theory and definitely brought it up to
where MOND and then sort of reverse MOND definitely
fits better with less missing matter, and, then there's
also the more of the "moving stars" and so on.
Then Relativity is just de-constructed a bit to its
principles, or, you know, good bones, and pretty much
later Einstein's is just fine, yet he did take away a
lot of what people were brought up on as "the thought
experiments".
