If you want to learn something about orbital velocity/mass/relativity then look up how Mercury's orbit was used to confirm general relativity.

There's also a good lesson in there on making predictions to confirm or contradict a theory.

        It is interesting how an honest dialogue often turns towards the absurd. - johannes - 11/30/2012 7:46:46 PM

        The calculations do not need to explain any theory to any layman. - alcaray - 11/30/2012 3:49:47 AM
