Re: Newton's 3rd law is wrong

I am not the first to say that Newton's third law is wrong.

Einstein said it before me (implicitly), with his General Relativity.

With my animation https://www.geogebra.org/m/v33hu4en I show what
Newton said.

Its gravity corresponds to the sum of the ratios between the mass <M>
(4) of the Earth and the mass <m> (2) of the Moon (numbers chosen for
ease of exposition): every single particle of the Earth interacts with
every single particle of the Moon, so that the total number (4) of the
red forces exerted by the Earth on the Moon is exactly equal to that of
the blue forces exerted by the Moon on the Earth (8 forces in total
corresponding to the product of the masses Mxm 4x2).

For this reason, according to Newton, the action of the Earth on the
Moon is perfectly equal and opposite to the reaction of the Moon on the
Earth, as prescribed by the third law.

Instead, Einstein argues that there is no force between the particles
of the Earth and those of the Moon, and that the action between the two
bodies is due to the space-time curvature of one in contrast to the
different space-time curvature of the other.

But the two curvatures are not equal!

And therefore, even for Einstein, the gravitational equality between
the two opposing bodies no longer exists, except in the one case in
which the two masses and the two curvatures are equal.

And never when they are different.
