Saturday is Sexy… Sunday is Movies Night
Hello, readers and friends of science..
So, if you have taken the time to read Part One of this series of Qs and As, this is the time to jump right into the follow up questions.
Math has certainly evolved enough to do a very good job of describing gravity. For most purposes Newton’s calculus and force laws, more than 300 years old, work well. For greater accuracy, one needs General Relativity, but even that uses math that had already been developed before 1917.

Follow-Up #2: Repulsion of gravity?
If you don’t follow all of this, don’t worry. I had to go and ask our local quantum field theorist guru for an explanation a few years back when a similar question came up.
