I wonder if the statement about Newton's second law (there exists an r(-t)) holds true when you include relativistic effects.

- calhoun137 12y agoTime is reversible in general relativity, in the sense that if you replace t by -t everywhere the solution is still valid. I don't remember the full proof off the top of my head, and the argument I do remember is complicated.
