You know what?
Every Fall, tons of leaves fall down to the floor and stay there till they start rotting.
You know what that causes?

It makes the earth spin about 0.000006 seconds faster.
Now think about your theorie of 6 Billion people jumping at the same time.
Most likely, it won't do shit.
Anyway...even we were heavy enough, we are spread all across the surface of the earth so our actions would cancel eachother.

The order of magnitude difference is 13 or so. In other words, humans suck at doing anything to the Earth.

This. Not to mention that there is a fairly even dispersal of people around the earth, making the total force much closer to zero.

Still, no force is applied. This is like saying "What happens if you stand in a bucket and lift yourself?"

Furthermore, velocity + gravitational interaction with the sun. Derp

Thread closed for being retarded.
