• You﻿ try getting good audio on the side of a telescope dome on top of a mountain! ;p

• every sun eclips the sun gets less covered﻿ by the moon. this shows the moon is moving away from the earth. i cant explain but it is true.

• I wonder what would happen if Earth were to escape Sun's gravity or fall to it. Imagine Earth accelerating!!! The whole earth would become like a fighter jet. Everyone﻿ on earth would feel a lot of G's lol. I wonder how that would feel?

• ....yah.﻿

• When I heard that I was like﻿ "What?"

• apparently the moon is moving away from the earth at a rate of about 3.8 centimeters﻿ per year

• Accurate to the first part. But if the moon were going slower or faster, it would simply take an elliptical orbit rather than circular. You'd﻿ really have to slow it down a hell of a lot before its path came near enough to the earth for the moon to collide with it.

• its 11km/h going up so that gravity doesnt pull it back﻿ down i think

• we already do. we use planets like mars and jupiter to get﻿ space craft to gain speed when traveling to the outer solar system

• Even the fastest moving tennis ball will come back to earth? No! Of course,﻿ no one could throw that fast or it may vaporize while flying through the air. How much is the escape velocity?

11km/sec?
