One person’s jump is practically negligible when compared to Earth’s internal forces. But, what if everyone jumped together at the same time? There are roughly 7 billion people on Earth, with a total weight of approximately 350 billion kilogram. What if we all jumped together at once? Are we able to shake the planet? Are we able to slow down time? Although this might sound like a fun global unity thing to do, one has to plan such a large-scale experiment more careful. This is because people are spread around the planet’s continents, hence if we all jumped in our normal locations, all the lift-off’s and impacts would cancel each other out! To avoid ending up with a zero net force on the Earth people will need to move to one place. Michael Stevens took this matter more seriously.
