Contrast between body and link text would pass against a white background but it fails against PF's light grey background...

It appears to me that they are currently distinguished by both color and brightness, as per G183. @Greg Bernhardt can you tell us what...

I'd add the qualifier coordinate speed in both SR and GR is invariant in inertial frames since the 4-velocity of light, like any...

As both @Ibix and @PeroK said, the difference between SR and GR in this respect is that speed can only be compared locally. In both SR...

The two way speed of light is only guaranteed to be invariant for inertial observers. Your apparatus is not inertial. The difference...

General Relativity entails general curved geometries, but locally the geometry is Minkowski - technically, it's a Minkowski tangent...

I think we already do

And its value is independent of R. It does not become small for large R

More generally, for two system of coordinates ##x## and ##y##, one has ##x^{\mu}=f^{\mu}(y)##, so $$dx^{\mu}=f^{\mu}_{,\nu}(y)dy^{\nu}$$...

In general, you should separate the goals of clear understanding of physics versus knowing the history. There were many confused people...

Clock synchronization is inherent in any experiment to measure the one-way speed of light, which is the very title of this thread. So...

In my opinion arguments over or about the one way speed of light are pretty much a dead end, but rereading the post I see Peter was...

Their underlining is better than most because the underline is separated from the baseline of the text by a greater distance than most...

Yes, it is. The experts writing the standards you are citing are not actually saying what you claim they are saying. The standard does...

I am one such person and your suggested "improvement" marginalizes me. And you are misrepresenting them in favor of your personal...
