“The law of gravity holds precisely only in a perfect vacuum.”
This is another case of confusing the law with the scientific model of it, the equations. The law holds precisely, everywhere, the equations describing it are too difficult to solve except in the simplest cases.
I was totally shocked when I read that, thinking that there’d been some discovery that anti-gravity had been discovered, and matter is in fact made up of (net positively charged) gravitational dipoles.
