This next question is one of those you might expect to have an amazing answer, but it’s nowhere near as impressive. Perhaps now that there are 8 billion people on Earth, we could have a greater impact on the planet. But where could you put all these people to make them jump?
It’s important that we’d all jump in the same place because, if everyone jumped across the world at the same time, it’d have no effect at all. According to the physicist Rhett Allain, being in different places would cause zero net force due to the jumps and return to Earth all canceling each other out.
