Ok in my physics class we are doing planetary motion and stuff, we started talking about how the population of the Earth affects the force of gravity. So my question is does it? Also if say all of Earth's population was concentrated to one hemisphere and everyone jumped at the same time would it be possible to move the earth? Because when you jump just as you move up doesn't the Earth move down as well? haha these may seem like pretty dumb questions but i was just wondering.
