Newton's Universal Law of Gravity describes how gravitation behaves in RET, yes.
Newton's law of universal gravitation states that every massive particle in the universe attracts every other massive particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
Since this detail became a trolling lame excuse, we now have to be very precise with the words said to trolls:
Gravitation does not behave as Newton's laws say in RET. Gravitation does behave as Newton's laws say in most cases in
real science.
At least one troll wants to associate RET with the Hollow Earth hogwash, and a hollow Earth is impossible according to Newton's laws.
Those of us who are here trying to show how real science works should avoid the "RET" name, since the idea of a flat Earth is not in fact contrary other shapes of Earth, it is against all the scientists of the last 400 years or more and their work.
