Have you ever wondered what would happen if all world population decided jump right away. And if you haven’t asked yourself, now you will. There is a hypothesis that even the speed of rotation of the planet could change as a result of an earthquake. But is it?

As explained in a recent article IFLScience, there are already some scientists who have tested it purely for fun. It is logically impossible to make the entire population of the world jump at the same time. The reasons why this cannot be done vary. But you can take a sufficiently large number of people and extrapolate results using mathematical calculations.

That is exactly what the science journalist did seven years ago. Greg Foot in the program experiment Earth Labbelonging BBC. collected a total 50,000 people, which he asked to jump at the same time. He then compared the results with the real world population, which is currently around 8 billion people. The results are interesting, but not interesting enough to support the theory of change in rotational speed.

Even the entire population of the world could not slow down the Earth

The fact that many people jump at the same time may well cause an earthquake. In fact, seismic activity has even been detected near football stadiums during matches in which fans enthusiastically celebrated goals. So Foote and his team used seismometers to measure an earthquake caused by 50,000 people jumping. That’s how they saw it at a distance of 1.5 kmtremor value 0.6.

In fact, judging by what they say in IFLSciencea strong earthquake can somehow affect natural movement of our planet. For example, an earthquake in magnitude 9 which happened in Japan in 2011 slightly accelerated the rotation of the Earth, reducing the day by several 1.8 microseconds. It can be expected that calculations for 8 billion people in the world will give a similar result. However, to affect the rotation of the Earth and the length of the day, it would take an earthquake of magnitude 8, and for this, at least 7 million times more individuals.

Yes, there will be some movement.

Now it should be noted that the Earth would move a little if we all jumped at the same time. According to the calculations of a science journalist, the movement will hundredth of the radius of a hydrogen atom.

Come on, that would be a minor movement and impossible to perceive. If the reduction of days with the earthquake in Japan were already negligible, if we all jumped at the same time, there would be no effect. perceptible to us.

Of course, we would be satisfied that we were able to achieve the consent of the entire population of the world in something. Looking at how we have been doing in recent years, this alone would be worth celebrating.
