What would happen if all people on the planet will jump at the same time? Bashny.Net

Stupid questions is a great way to learn more about the world. And if you think about it, they're not that stupid, but curiosity has always been one of the main properties of the person.

Today we are in the Website has presented what would happen if all people on the Earth at the same time bounce.

For purity of thought experiment will gather all people in one place — for example on a piece of Land with an area of 1 thousand square km, the size of new York. And Yes, I imagine we're all going to fit.

• For example, weight 1 60 kg (let's not forget about the children and residents of Asian countries, which generally weigh less than Europeans).
• Living on the Earth are 7.5 billion people. It turns out, the total mass of humanity is about 450 million tonnes.
• The mass of the Earth is about 6 sextillion tons, that is 6 000 000 000 000 000 000 000 T.

It turns out, the percentage of the weight of all the people from the weight of the Earth is approximately 0,000000000000001%, well that is almost all zero. As you can see, we are not so much as think on a global scale. Physicist Rhett Allen (Rhett Allain) has calculated that energy from our jump is not enough to make something global. But:

• One of the most noticeable effects for us will be the sound of a billion feet, hitting the ground at the same time, this rumble will last for a few seconds.
• We will move the planet! But only about 0.25 nanometer. This is half of the diameter of a hydrogen atom — the smallest atom in the world. This shift will be completely invisible, and the Earth will almost immediately return to normal position.

By the way, there is another view, which is presented by astrophysicist Paul Sutter (Paul Sutter) and the physicist mark Boslough (Mark Boslough). In their scenario, the effect of the jump of all humanity will be much more noticeable:

• They believe that the sound of the landing of all mankind on the asphalt will be so loud (200 dB) that can break eardrums and even kill.
• There shock wave that will generate an earthquake of magnitude 4 to 8 points, which will cause the destruction of buildings and arrange a tsunami.

Which of these points of view to take — you decide. Personally, we thought that the first is more realistic. Maybe among you there are physics that can make your calculations?

By the way, the story was an example of when an earthquake with a large magnitude was provided to the planet a global effect. Scientists from NASA said that the Earth's orbit has shifted several inches, and the day was reduced to one millionth of a second after the earthquake in Japan in 2011.
