You must of failed the 3rd grade then, there is a very small amount of gravitational pull on the moon's surface.... How do you think we kept a module on it when we landed there? Why didnt Neil Armstrong just "float" away? :idunno:
You must "of" (I think you meant 'must've', a contraction of 'must have') missed his point. If you start stacking Coke cases, you will be beyond the pull of earth's gravitation enough so that the cases won't stay stacked before you get to the distance of the moon from earth.
Did you know that the reason for the seasons on earth have nothing to do with distance from the sun?
