What would actually happen if every single person on earth jumped at the same time?

It's an age old question that has had an array of answers over time, but finally there is an answer that scientists agree upon.

If we all jumped at the same time, the fact that we were all spread out over the earth would mean that the net force wouldn't have any affect.

This is because all forces would cancel each other out, so even if the earth did move a little as all the weight is shifted, it would go back to its original position as soon as we all landed.

Michael from Vsauce explains this theory here:

The other method of doing this would involve everyone in the world being magically transported to an area the size of Rhode Island.

This is the one we all have to be wary of doing, it involves the world ending, but not in the way you think.
