Not absolutely sure which Bill you mean. If you mean me, that's not really my problem; not that I restrict myself to only one!

My main problem is contained in my last post. How does the moon keep orbiting the Earth, exchanging potential and kinetic energy, apparently withour loss or input of energy?

A few people have already tried to explain this to me, but either I have a bad blind spot, or there is something still unsaid.

There never was nothing.
