    Nope. Equal and opposite forces from taking off and landing.

    Wouldn't that constitute the "same affect" as doing it the other way? "You get that which you tolerate"

      Not really. Jumping exerts a downward push sufficient to overcome gravity and jump x cm into the air. gravity then accellerates you body until it re-impacts the earth imparting (again) a downward force as the kinetic energy is dissipated. Granted, at the apex of your jump, your gravity acts on earth with the same force as it does you, but the mass difference make accellaration of the earth inconsequential. Even so, this sounds like bunk to me.

        I think removing a person from the surface of the earth, has more effect than had that human jumped up and down a million times. There's a lot of loose and fluid stuff between earth's center of gravity and its crust. :)

        I think all the volunteers should climb to the top of the highest building in their vecinity and jump off (timing the leap so that all will strike the round together). That way we eliminate the most negative component to the human gene pool at once...

          The Weekly World News once uncovered a plot that the Chinese were all going to jump simultaneously, pushing the earth out of orbit and thus destroying our capitalistic way of life. I don't know if it worked.

          It is happening, but they didn't need to jump to succeed

            In practical terms they have the same non-effect. In more theoretical terms, jumps have to occur at specific places in the orbit so that they will have a combined effect and not cancel each other out. If the sun were not there and the Earth moving in unconstrained motion the Earth would shift slightly and then move back to the same path while you jumped. Similar to what would happen if the Earth split in 2 and and merged back together each part would have a little hump in it's path while it was seperated and then merge back to the same straight line. With the Sun's gravity that hump means that the Earth would experience slightly different gravity while it was displaced from its path. This would cause a slight change in its direction. If you time your jumps so that the motion of the Earth always moved it to an area with weaker gravity you could eventually change the orbit of the Earth. Some of the plans to divert asteroids use approaches like that, except it is much easier since they are soo much smaller.

              I think the effect might be greater if it involved a ship, the middle of the ocean and a heavy rock. Either that or a rocket getting them off the planet forever.

                Actually, it kind of backfired since many chineese became the worst capitalist. Their hard and raw capitalism might just destroy are way of life...

                  Perhaps they jumped the wrong way? :doh:

                      This is so stupid, havent they heard of Newtons third law? Action reaction etc? In any closed system, it doesnt matter what the mass does if it isnt ejected form the system, it can have no action upon what is left of that system. Even Mt St Helens, if its ejecta is not thrown into space and away from the earth will not move the earth one millimeter. Nunc est bibendum
