You can see moons orbiting Jupiter, and all of these other signs of GRAVITY out in the universe. But I'm not even going to argue that.
Oh man!
Moons going around planets demonstrating that the concept of gravity-bound orbits - a conerstone of Round Earth Theory - is valid?
Please, please, please stick this ina new thread for debate.
My question would be, though: can an amateur astronomer with a medium-sized telescope actually see the Galilean Moons disappear behind the disk of Jupiter?
