Vladimir Erashov argues that in the Moon-Earth system, the latter should experience oscillations that are three orders of magnitude larger than those observed experimentally. What is this mysterious mechanism that balances the Earth's vibrations by three orders of magnitude?
The moon has an elliptical orbit, its distance to the Earth varies (roughly) from 355 thousand kilometers to 410 thousand. The Earth and the Moon revolve around a common cent of masses, make 12, 3687479572 revolutions relative to the Sun in a year, and 13, 3687479689 revolutions relative to stars. any reference book will confirm you and all this is known to science as our Father.
According to the law of conservation of angular momentum, the speed of rotation of the Earth-Moon system around the center of mass depends on the distance between celestial bodies, and therefore it is variable. It is maximum when the distance between the Earth and the Moon is minimum and minimum when the distance is maximum. Since the distance between the Earth and the Moon changes by 410-355 = 55 thousand kilometers, this is about 13%. The angular velocity of the system should also change by the same percentage. Since the Earth makes a total of 365 revolutions per year relative to world space, 13 revolutions relative to the Earth-Moon center of mass are 13/365 = 0.0356 or 3.56%. According to this arithmetic, the fluctuation of the Earth's rotation speed should be 3.56: 13 = 0.2738% or 0.002738 of the natural value. Such fluctuations do not occur in a day, but in a lunar cycle of 27, 55455 days. Divide, we get the speed per day by the factor of ellipticity of the orbit should fluctuate by 9, 94 to 10 to the minus fifth power. This will be approximately 0.81 seconds.
In reality, the speed of rotation of the Earth, even during the lunar cycle, fluctuates by 1-2 ms, that is, 1000 times (roughly) by a smaller value than it should fluctuate in terms of the elliptical orbit. - Vladimir Erashov.
We will remind, earlier the Kramol portal reported that the Earth-Moon pair is moving not around a common center of mass, as it would be according to the law of universal gravitation, and the ellipsoidal orbit of the Earth contrary to this law does not becomezigzag (the Earth vibrates in only one direction - along its own orbit around the Sun).
We also recommend a detailed article by physicist Andrei Grishaev, dedicated to this and other oddities of gravitation: Spillikins and wicks of universal gravitation
