  • What will happen, if all 7,000,000,000 people on earth simultaneously jump up and down?

  • If everyone jumps at home, nothing significant will happen.

  • That is - nothing at all.

  • Even if we jump up and down the whole day long.

  • But, if we were to collect all people of the earth in one place, we could very quickly solve a rather important problem: Overpopulation.

  • Probably you have heard something about us humans multiplying our numbers much too quickly.

  • There are just too many of us on earth.

  • If nothing is done, soon there won't be any food left.

  • One way of looking at it, 7,000,000,000 is not so much,

  • so all the people on earth could easily fit into a territory equal to the size of Moscow or Los Angeles, for example.

  • And it wouldn't even be crowded.

  • OK, let's say we all gather on a hypothetical huge platform one meter of the ground and are ready to make this collective jump.

  • What will happen?

  • This jump will create a truly significant amount of energy, part of which will return back to each person through their shoes.

  • And, some of which will dissipate into the environment with very interesting consequences.

  • First, you will hear a very loud sound of about 200 decibels, similar to the sound of applause, only much much louder.

  • A jet engine emits a sound volume of 140 decibels.

  • 160 is the level of a shock wave from a supersonic aircraft.

  • The pain threshold of a human being is already passed at a level of a mere 130 decibels.

  • 135 to 140 decibels is a concussion.

  • 150 shock and severe injuries and 200 decibels - at best such a sound will simply blow your eardrums.

  • That's at best, but basically, everyone will just die.

  • Suppose you're only deaf after the jump.

  • Somehow, you survived.

  • You are incredibly lucky, but not for very long.

  • It turns out that our jump strongly impacted the planet and in response to this degradation the earth will send a 30 meter high tsunami rolling back onto shore.

  • Along with a couple of earthquakes of around 4 to 8 on the Richter scale.

  • As a consequence, bridges, railways, powerlines and some buildings will be destroyed.

  • The apocalypse is here.

  • But, I must confess to you nothing will happen.

  • I misled you.

  • If we were able to bring together 7 billion people and make them jump at the same time, everything would be like this:
