What would happen if everyone in the world jumped at once? Nothing really. The collected mass of everyone in the world isn't big enough compared to the mass of Earth. If we all jumped at the same time Our force would propel Earth away from us, but not very far at all. Earth would only move away from us 1/100 of the width of a single hydrogen atom. In the end Earth as well as the world's population would return to its original starting places. If we wanted to be able to move Earth we would need several times more people than we have now. If we had that many people we would resemble the strength and power of an earthquake. Some earthquakes have the power to redistribute mass such as the one that took place in Japan, 2011. That earthquake was so powerful that it moved a lot of mass towards Earth's center that every day since has been .0000018 seconds shorter. Not a great change but it's still a change.
But say if you jumped at a certain location such as T.F. Green Airport? Would anything different happen? Interestingly enough yes. The energy created by the action of 7 billion people jumping would create a loud sound of 200 decibels. This would be deafening because a human's pain threshold is only 120 decibels which means everyone who jumped would never hear again. Yikes. Because T.F. Green is near the coast as well there would be a slight chance the energy would create a tsunami. As previously mentioned we could possibly create an earthquake and that in turn could trigger a tsunami.
All in all we won't ever really know what will happen if we all jump at once until we all jump at once. But seeing as these may or may not be the consequences to everyone jumping, I say let's hold off on this experiment for the time being.
