Am I in the Twilight Zone???
How would you explain the apparent progression of the sun, as you sat on the moon?one_raven said:If you are sitting right on the nose of the man in the moon and looking at earth, you would see the earth rotating, but it would never be out of your sight.
I understand what you are saying about relative motion, but my answer would be no.

Bull. You've never been involved in physics research.I am being serious, alright. My science is fundamentally rusty, I agree, since it's been over 12 years since I was involved with science research
Perhaps he means psychic research.Bull. You've never been involved in physics research.
The natural decline of the Earth's gravitational field strength is a simple and elegant solution.

I'm not claiming to be an expert. Perhaps you can summarise the models for me?

Your explaination of decreasing gravitational strength, on the other hand, would have all satellites receding from their planet regardless of the type of orbit, and this does not match what we actually see in practice.
There's nop need for you to lie. If you didn't lie about having done aeronautical research, that doesn't mean you've done physics research. My father has worked with Lockheed, Boeing, Airbus, the development team for the Eurofighter and even the supersonic car. He doesn't know the first thing about theoretical physics research. Doesn't even know the concepts in it!No need to get personal.
How so? You don't even know modern physics, you're making mistakes in this forum which are on material taught to people doing GCSEs and A Levels. I did circular orbital velocities when I was 16 or 17. You claim to have a degree in astronomy and you don't know about orbital velocities? I teach people doing degrees in astronomy and they know about such things!Incidentally, anybody with common sense can see that modern physics is floundering.
We don't, not to the level of accuracy we know the Moon is. But given places like Io experience even more tidal interactions with their parent planet than our Moon does with the Earth and all models of Newtonian and Einsteinian gravity predict such behaviour and we have not found any reason to doubt such results yet, the models are not invalidated.So how would we know whether other natural satellites are receding from their parent planet or not?
