First Postulate as it relates to
Special Relativity per Wikipedia.
Note the link to 'principle of relativity' which gives a fairly good description of General Relativity, where the 'equivalence principle' is described. No problem with that, nor with the second postulate on lightspeed v = c. My question is whether or not we can assume the first postulate is correct, that
'the nature of the universe must not change for an observer if their inertial state changes'. Another way to say it is: 'the laws of the universe are the same regardless of inertial frame of reference'.
This is a key point, that IF all reference frames are NOT equally valid, for the observer or the observed, then though we may treat them mathematically as valid, they may not be. The default is then that relativity is what it always was, an observational study from the observer's reference frame. Observing relativistic events requires factoring in relativistic velocities and acceleration, without transposing those observations unto the universe, nor the observed. Once you change the inertial state, meaning you accelerate a frame, it is NO LONGER the same frame it was in its rest inertial state. The laws of the universe have not changed, of necessity, but calling the same frame in its rest phase or accelerated phase as if it remained the same is a conceptual error. That error, that there are no preferential reference frames, meaning that accelerated frames are equally valid in terms of the laws of the universe to the rest frame, will then carry throughout conceptual developments of any theory derived from it. Do you have any idea what that means? It means you can build a whole theoretical framework on a false basic premise. The math is beautiful, elegant, incredibly refined, but it leads to nonsense. That is the univese we've been given over the past hundred years, and it is time to stop it.
But now I'm drifting 'relativistically' far off topic. Sorry. Has nothing to do with Huygens, variable G, nor variable c. Those will be discovered through observations dedicated to finding them, experiments designed to measure them, and not incidentally because the clamps released Huygens from Cassini without incident (or one reaction wheel failed, per
Tassel's above, by spinning up to 300 rpm vs 50 rpm designed), and the probe got pulled into Titan's gravity successfully. I would think real science would like a somewhat more durable and dedicated proof, then settling for a whitewashed version of it. Then you'll say "GR has had ample proof and that EP has been verified"... and I'll say "yes, EP has been verified at ~ 1AU, but GR only within the parameters of the mathematics of Relativity"... and you'll say "then you are ignoring the findings of professional scientists"... and I'll say "findings based on an erroneous premise"... and you'll say "a hundred years of research cannot be proven wrong by your saying it is wrong"... and I'll say "the research was good only within the context of unverifiable assumptions of the first postulate"... and you'll say... "verifying EP proves GR, which proves the first postulate"... and I'll say "wrong, it only verifies EP, not the first postulate"... and you'll say "we've been through this before, so you're refusing to accept you're wrong"... and I'll say "right." ... Been there, done that.
