EINSTEIN'S GENERAL RELATIVITY AS A DEPARTURE FROM LOGIC

https://plus.maths.org/content/what-general-relativity
David Tong: "Newton's and Coulomb's formula are nice and neat, but there is a problem. Going back to Newton's law, suppose you took the Earth and the Sun and very quickly moved them further apart. This would make the force acting between them weaker, but, according to the formula, the weakening of the force would happen straight away, the instant you move the two bodies apart. The same goes for Coulomb's law: moving the charged particles apart very quickly would result in an immediate weakening of the electrostatic force between them. But this can't be true. Einstein's special theory of relativity, proposed ten years before the general theory in 1905, says that nothing in the Universe can travel faster than light -- not even the "signal" that communicates that two objects have moved apart and the force should become weaker."

David Tong is lying of course. The weakening of the force may undergo some delay but this has nothing to do with special relativity. The theory based on Einstein's 1905 postulates does not predict anything about signals travelling in gravitational or electrostatic fields.
