What If Everyone On Earth Jumped At The Same Time? - Science ABC

If everyone on Earth jumped at the same time, nothing would happen. The mass of all humans is minuscule in comparison to the mass of the Earth, so their combined jump would have no effect on the planet’s movement.

As kids, we used to play all sorts of games. Some of them were silly, some were creative, and many would make absolutely no sense whatsoever to our adult minds. I remember one game in particular that involved jumping, and while I can’t recall the exact rules of the game, I vividly remember that kids used to stand in a circle, holding each other’s hands and jumping together (I am sure there must have been a particular reason for this, but I have no idea what it is). The one who did not jump at exactly the same time as the others would be disqualified.

As we grow, these activities seem a bit too strange to perform, particularly in a public place. However, think for a moment about what would happen if all the humans on Earth played this game at the same time? What if everyone stood close together and jumped at precisely the same instant.
