2. you have no idea who you are talking to
It would be wiser to be more polite when being given a free education by one who knows far more than you on a given subject.
As to Newtonian Mechanics as apply to inertia, you give only a partial definition, which may explain your error. The Law runs in full: "An object at rest shall remain at rest, and an object in motion will remain in motion with unaltered vector, unless acted upon by an outside force."
The tidal effect of gravitation in a binary system is an outside force.
I agree, I was rude. I was already in an agitated state from an outside sourse and should not have responded that way. I understand the tidal force, but it would seem that it would be very small and cyclical. Please explain. However, I do understant that many people at least as smart as you believe the moon has always orbited that way.
Perhaps I mixed up my planes? LOL not Cessna or Piper either.
