try this right now:
Make fists with both of your hands and then with your arms in front of you keep your left arm and fist static as you rotate the fist of your right arm around the static left fist.
Observe for a while how the rotating fist appears to display all of its surface area at some time during its rotation to the static fist.
Now, Imagine that these two fists were actually disembodied and floating in space. Gravity and friction would not be a concern except for the gravitational pull of the two bodies as the rotating fist which is smaller in mass rotates around the larger static fist.
Now imagine that the larger static fist is in fact the Earth and it is is travelling through space at 63.000 miles an hour and obeying all the laws of physics as we currently understand them. Now observe the right rotating fist (moon) and try and make it only display one part of its surface area to the the planet it is orbiting.
Did you feel it? ........................:roll:
