Point taken, but this may be a difficult concept for some people, and is worth discussing.

If you take the "Looney Tunes" idea of having a fan blowing your sailboat's sail - well that's a good idea of what you're saying, Jet-Lee and I agree it wouldn't work.

Jumping off a boat that's in the water is different, however. The boat moves in reaction to the energy your legs provide. A simple case of basic physics - for every action there is an equal but opposite reaction.

Now take the larger example of jumping off of the planet. To our perception, the planet doesn't move. But where did the energy of our jump go, if not into moving the planet some infinitesimal amount?

if we jump OFF of the planet (assuming our legs can accelerate us to 7 miles per second) then yeah, the planet will move... a liiiitle bit. But the fact is, all the eneregy we put on the planet by jumping away from it, is returned from gavity pulling us back. And when we smack down on the earth, the earth is smacking us with exactly the same amount of energy that we are it. Therefore, net work done = 0

*edit* seriosuly, and i don't mean this in offense to anybody, but to whomever is having a hard time with this concept, go to your local library and read up on a physics book. It's quite fasciating stuff IMO.

i'm not having a hard time understanding it, but i am SO excited to see YOU guys so excited about it!!!

i dont think everyone jumping would make a difference, though =my uneducated assumption.
