Reality Check,

That is an attack on the person, not the idea. It is inappropriate and inflammatory. Take it down a notch.

The present is still that you have made your own ATM idea wrong by getting the radius of the Earth wrong from still not described math. No only is the value wrong, by not describing the math we cannot even tell where you went wrong.

Now we have another image and not described or cited experiments.

There is no "dependence of an electromagnetic frequency on the gravity acceleration" in the many scientific pendulum experiments that have been done for centuries. Gravity will not affected by electromagnetic frequency from some unstated source.

The frequency of electromagnetic waves is not restricted to a single value as in your next image of a formula.

g is the acceleration of gravity at the surface of the Earth: g = GM/Re2 where M is the mass of the Earth and Re is the radius of the Earth.

A guess that astronomers cannot measure the radius of the Earth to within 3-4 kilometers will not work. The equatorial radius is 6,378.1370 km. The polar radius is 6,356.7523 km. The standard in science for measurements is to write then to the last significant digit, i.e. the one with the error in it. That is 6,378.1370 +/- 0.0001 km and 6,356.7523 +/1 0.0001 km. The source for the equatorial radius states that the uncertainty is 0.1 meters. The mean radius is 6,371.0088 +/1 0.0001 km.

Maybe they have chosen wrong frequencies and lengths of pendulums for centuries. I really have got some strange resonances that cannot be explained by the standard oscillation theory of a pendulum like a suspended string. Maybe the reason of getting these resonances is that I live in the neighborhood of the 43th parallels ( see my comment #50 ). This all requires study.

Let's assume it so, but how correctly are the radii measured - from the sea level, from the Mariana Trench, from Mount Everest or other mountains and sea trenches? This all is ambiguous. Maybe scientists have solved one thing, but Nature has decided differently. Sorry, but 3-4 km in comparison with the huge Earth is almost nothing. I do not think that this small difference is essential.

I'm not sure. So I asked my question.
Considering that there is no real evidence that physical constants have different values on the moon (we've been there!), and it is fairly easy to come up with coincidences like this, I'm afraid you're going to have to, in your words, one should "acknowledge that the formulas obtained are some accidental coincidences for the Earth."

It's an interesting coincidence, but it's not very unusual--even if it does get the units right.

5. Spacefaring nations, for years, have accurately navigated near and even upon bodies of the solar system using constants you tell us must be incorrect.

How do they accomplish that?
