Question

How did Einstein’s and Newton’s theories differ in terms of explaining the cause of gravity?

Answer 1

Newton's law of universal gravitation doesn't say anything about the cause of gravity.

Einstein's theory of relativity does.

Answer 2

Newton”s theory says this can occur because of gravity, a force attracting those objects to one another or to a single, third object. Einstein also says this occurs due to gravity- but in his theory, gravity is not a force. It is a curve in space-time.
