Even if they could, we know their clocks run at different rates, owing to GR. What, precisely, is the problem?

Which all of the republicans voted against (and IIRC, have vowed to repeal)

That’s irrelevant to how you framed this, though. You said “the liberals are not pushing for economic improvements” rather than assessing the liberal-ness of the programs. They have definitely pushed for economic improvements. How liberal the programs are is another discussion. Democrats passed Obamacare, and that included medicaid expansion. States that have not taken advantage of medicaid expansion are run by republicans. That’s not the fault of democrats. Most congressional Democrats support increasing the federal minimum wage. The problem is there is no Republican support, so no legislation can be passed. States that have low minimum wages tend to be run by republicans. Same goes for regulation. You need better sources of information. ETA: Is this a democrat or a republican

Why isn’t “don’t let them in. Only shoot if they break in” an option? (I think there’s a fundamental issue of trying to impose ethics of our universe on a scenario that takes place in a place where different natural laws apply.)

If they are sent in the same exact direction, how do observers at transversely-separated locations each get a photon? As to the scenario: do the two observers agree on the speed of light? Their clocks will disagree, and each will get the correct value of c when measured locally. What implications does that have?

That’s valid for a compact space, a restriction not specified for the general case.

“In theoretical physics, a preferred frame or privileged frame is usually a special hypothetical frame of reference in which the laws of physics might appear to be identifiably different (simpler) from those in other frames.” It works for any inertial frame, though, so that one frame is not a preferred frame. The scenario has an accelerated frame, and accelerations are not relative. That’s the crux of the matter.

Not liking (or understanding) the answers is not the same as not being given the answers.

That’s not what is meant by a preferred frame.

What experiment does this math agree with?

As KJW notes, the Sagnac correction is in accordance with SR. More importantly, there’s no correction for the effect that you claim is present.

That doesn’t answer my question.

You haven’t convinced me it’s not a waste of my time.

And yet you agree that there is no actual length contraction despite it being a part of your model. Why doesn’t that count as disagreeing with experiment?

I wasn’t either, but then, an unpublished (other than a letter to the editor) experiment doesn’t really have a big radar cross-section.

Poorly formulated question. “should” implies a preferred result or intent. Accelerated expansion implies dark energy. Do you know what an unstable equilibrium is?

It matters if you have an understanding of the science involved, even if you don’t accept it. It’s clear that you don’t; most of your OP is wrong. Subsequent discussion has shown even more misunderstanding GR tells us a static universe is unstable. So it’s either contracting or expanding. The evidence says it’s expanding.

You can be as incredulous as you want. But your deficient level of understanding does not convince me that my understanding is incorrect. It does not validate your rejection of scientific results, or acceptance of flawed experiments The fix for argument from incredulity is for you to raise your level of knowledge and understanding. And, as zapatos notes, equating the logical fallacy with some virtue is yet another logical fallacy.

Argument from incredulity is not a persuasive objection.

We have a thread addressing this https://www.scienceforums.net/topic/89395-what-is-space-made-of/

Why is it that satellite time transfer does not address your issues? You mean the experiment that has been shown to be flawed? And was never published as a peer-reviewed article? That Silvertooth experiment?

So Bidenomics is something I’ve hallucinated? No inflation reduction law, infrastructure act or CHIPS and science act?

I saw an ad for an electric cooling blanket, which could work if it was employing peltier coolers. Also one that pumps cooled water through it.

It’s like calling a cotton short-sleeve shirt a cooling shirt that you should wear when a wool sweater would make you too hot. Marketing. But as J. C. notes, some people like the weight of a blanket. IMO it’s not any more of a scam than other advertising language is.

Not if the theory doesn’t match experiment. Those models go into the trash bin. The size can’t depend on the method of measurement. And if the method only works for some very contrived situation, it’s not particularly useful The time isn’t the issue - it’s what we knew then vs what we knew later. I take the title of the paper to mean “here’s an interesting peculiarity about electrodynamics that turns out to have application in a more general sense” IOW, even though it was first noticed in electrodynamics, it’s not about electrodynamics.
