Simulating Physics with AI
This was actually done years ago, before we called it AI. https://news.cornell.edu/stories/2009/04/computer-derives-natural-laws-observation “The researchers have taught a computer to find regularities in the natural world that represent natural laws -- without any prior scientific knowledge on the part of the computer. They have tested their method, or algorithm, on simple mechanical systems” I think there were other efforts, and there are more recent examples

Bulging bat barrels breed better baseball batting?
It’s wider where some hitters contact the ball, which also moves mass toward the hands, so the same torque will let it accelerate more. So it’s wider without being heavier. Heavier bats would be slower. One key was analyzing the contact area and realizing that it was closer to the hands than was assumed. That’s not the case with all hitters, and only some hitters are using the new bat.

The Kim et al. (1999) Experiment: A Curious Twist
That’s a strawman. You don’t seem interested in following the rules, or a discussion in good faith, and despite having been given ample opportunity to comply, you have not done so. That is why this is locked.

The Kim et al. (1999) Experiment: A Curious Twist
Perhaps you can explain why you think the Hong-Ou-Mandel effect has any relevance here. You offer it as proof that aberrations happen, but it’s not evidence of any aberrations in this particular experiment. So it’s a red herring. And you haven’t really shown more knowledge here than you did about atomic clocks, or how science works. The chip-on-shoulder act isn’t going to work to bluff your way through this. You either follow our rules, or this gets locked.

US assault on free speech and freedom of expression
No, it’s not just you, it’s become all too common. Someone posts “I like pancakes” and some idiot responds “why do you hate waffles?” It’s the fallacy of argument from siilence. But some people do like to communicate in bad faith. It’s unreasonable to expect comprehensive coverage of topics, especially in short-form communication like social media, but even books and articles have length/scope limits.

The meaning of constancy of the speed of light
If you change what the laws of physics are, you throw GR and electrodynamics out the window. So there is no guarantee of an invariant c. Come up with laws that hold in an accelerating frame, for instance.
-
The meaning of constancy of the speed of light
That’s much more than you were claiming, though. A change in the definition of time is not just changing the definition of the unit. You were arguing the opposite - that the unit definition drives the laws. “the laws of physics those experiments perceive when using those standards” Our unit definitions are based on our known laws of physics, which are interdependent. If you redefine what acceleration means, a whole bunch of stuff could chamge. That a whole other argument. No, as Markus stated, in a completely different argument about laws, rather than unit definitions.

The Kim et al. (1999) Experiment: A Curious Twist
Lazy You’re asking for other people to give you their time. Adding hurdles isn’t helpful, and the rules require that things for discussion be posted here. Besides, that link goes to a PRL which is paywalled. You want to find the ArXiv version, which is not. https://arxiv.org/pdf/quant-ph/9903047 But does not show “leaning” fringes that you are making unsubstantiated claims about. No, it’s claims based on no experiment, and unproven physics conjecture.

The meaning of constancy of the speed of light
And yet you bring up situations where these don’t matter, because the experiments don’t rely on them. He uses ideal, perfect clocks, which don’t rely on the definition of any particular unit system, rather than real world clocks. And his concept of time is that of physics - it’s what’s measured by a clock. I don’t know what this is supposed to mean. Can you cite an actual experiment, rather than a contrived one? What’s an “SI atomic clock”?

The Kim et al. (1999) Experiment: A Curious Twist
! Moderator Note How? You don’t give a link to the experiment or even a proper citation. Then do the experiment and write it up. Until then, there’s no actual science here. It’s just “what-if” conjecture.

Falsifiability
That's likely for a theoretical flight with some given parameters (probably same speed E and W) In the Science paper (Science, New Series, Vol. 177, No. 4044. (Jul. 14, 1972), pp. 166-168) based on the actual flight parameters, the predictions give gravitational, kinematic and net effects The paper after that one gives the experimental results. I'm not sure why you would expect confirmation to happen pre-experiment. Predictions are the values expected from theory. Not at all. You can run the numbers yourself Once again, the relativistic effects only depend on the orbital/flight parameters, so there's no legitimate reason to expect new values if a different type of clock is used. Part of Einstein's theory is that the type of atom has no effect (Equivalence principle - effect of gravity does not depend on the composition of the matter)

Falsifiability
You fail, once again, to specify what frequency. More than one component in an atomic clock has a frequency. Skimping on info isn’t the right tactic if you want to convince people. Why don’t we see this effect with co-located clocks of different species as atmospheric pressure changes?

Falsifiability
As I said, it’s the quartz oscillator, at 10.23 MHz, that’s adjusted. The Ashby reference says this. You should have read the whole thing, because it also gives the follwing story about the shift “There is an interesting story about this frequency offset. At the time of launch of the NTS-2 satellite (23 June 1977), which contained the first Cesium atomic clock to be placed in orbit, it was recognized that orbiting clocks would require a relativistic correction, but there was uncertainty as to its magnitude as well as its sign. Indeed, there were some who doubted that relativistic effects were truths that would need to be incorporated [5]! A frequency synthesizer was built into the satellite clock system so that after launch, if in fact the rate of the clock in its final orbit was that predicted by general relativity, then the synthesizer could be turned on, bringing the clock to the coordinate rate necessary for operation. After the Cesium clock was turned on in NTS-2, it was operated for about 20 days to measure its clock rate before turning on the synthesizer [11]. The frequency measured during that interval was +442.5 parts in 1012 compared to clocks on the ground, while general relativity predicted +446.5 parts in 1012. The difference was well within the accuracy capabilities of the orbiting clock. This then gave about a 1% verification of the combined second-order Doppler and gravitational frequency shift effects for a clock at 4.2 earth radii.” Those numbers are figments of your imagination, which is why they aren’t in the literature. The Ashby reference is from 2003, and is well-known. No need for later references to explain it. And proper references would include authors and journal names. Can’t check them with the scant info you’ve given It’s in the one reference you provided. Look near equation 36 You put this in quotes, and yet I never wrote that sentence.

Falsifiability
Really? “Environmental conditions can affect them. High pressure? Lab data backs it: crank pressure up a torr, and frequency drops ~0.1 Hz.” Sounds like atmospheric pressure to me. You say if pressure cranks up a torr, frequency will drop by ~0.1 Hz. But there’s no citation to where this information came from, and you don’t specify what frequency changes. Your later calculation suggests it’s the transition frequency of the atoms. Which are in vacuum, so that would be a neat trick. But if pressure cranks up a torr, that’s about 1/760 of an atmosphere - a little more than 1%. But it routinely varies by about 25x that owing to weather, and we don’t see effects from it. You are making stuff up and/or grossly misunderstanding the details. Without knowing where you got your “information” it’s hard to assess how much of each.

That’s a shift in the quartz oscillator frequency, and is there because of relativity. Not pressure.

Falsifiability
Where is this rerun? You’ve not provided a single citation to an actual experiment. Clocks in orbit - no pressure at all - don’t see the differing shifts you predict. GPS works. Galileo works. Other satnav systems work. This falsifies your premise. If you support falsifiability, you must abandon your conjecture. They are the timing errors you’d get for a 10Hz shift in the transition frequency for Cs, Rb and H. They signify being pulled out of the OP’s ass, on the idea that changing ambient pressure would shift the frequencies. That’s nonsense, of course. Atmospheric pressure changes without having to go into an airplane or satellite, because it changes over the course of a day and with weather. If that affected atomic clocks differently, then a site with Rb, Cs and H clocks (say, the US Naval Observatory) would see such behavior, and timing wouldn’t work. No such behavior is observed - not at that scale, at least. Quartz oscillators and electronics have some small susceptibility to it, but it’s nowhere close to this level.

But they were different kinds of clocks, as I said. In addition, DSAC used a mercury ion clock Different gravity? How does gravity differ going east vs west? Centrifugal force? (it would be centripetal, since we analyze in an inertial reference frame, and the centripetal force would be that of gravity) Reference? And this would be different going east vs west? hand-waving isn't going to convince anyone who understands physics. All of the types of clocks behaving the same way is a problem for relativity? Sealioning and this strawman doesn't serve you well. If you had some effect that gave you a constant offset frequency, there might be an issue. But all you've done is make something up, and that's certainly not a problem. I'm no longer surprised that people think LLMs give universally trustworthy answers. Just disappointed, since there's so much evidence to the contrary. You haven't actually presented any science here. Just assertions, with nothing to back them up.

The meaning of constancy of the speed of light
Radio clock? In that you are synchronizing to a remote source? You can't say that they tick at the same rate regardless of where they are, since you aren't relying on that clock, you're relying on the remote one. And you will notice that they get out of synch faster depending on where you are in a gravity well or how fast you move. If they didn't, you wouldn't have to continually reset them Exactly. It's not the local clock that's telling you the time, it's the remote one. Your notion that it doesn't vary with the location is a misrepresentation.

Falsifiability
I didn’t claim that falsifiability does not apply. If you experimentally confirm something a thousand times, one outlier points to a flaw in that particular experiment. You’d need to explain why the thousand experiments just happened to work. Nope. See above. Nothing dogmatic about statistics. If you’re just going to manufacture strawman statements, it just points to you having an agenda. It’s not at all subtle.
