What Would Happen If The World Lost Oxygen For 5 Seconds?

Have you ever imagined what would happen if oxygen from the Earth was lost for just 5 seconds? To find out more read and see the video below.

  • Everyone at the beach would immediately get sunburns. Molecular oxygen in the air protects our skin against UV light.
  • The daytime sky would get dark. Fewer particles to bounce light means a dark, almost black sky.
  • All pieces of untreated metal would instantly spot weld to each other. The only thing preventing metal from welding together on contact is a layer of oxidation.
  • The earth’s crust would crumble. Oxygen makes up 45% of the earth’s crust.
  • Everyone’s inner ear would explode… because we would lose about 21% of the air pressure.
  • Every building made out of concrete would turn to dust. Oxygen is an important binder in concrete.
  • Every living cell would explode in a haze of hydrogen gas. Water is 1/3 oxygen, without it hydrogen would turn into a gaseous state and expand in volume.
  • The oceans would evaporate and bleed into space. Without oxygen hydrogen is free to float to the upper troposphere and eventually into space.

Now, what if the amount of oxygen doubled?

  • Paper airplanes would fly further.
  • We would get better gas mileage.
  • We would be happier and more alert.
  • The extra oxygen would improve our cognition, alertness and physical performance.

But…
There would be giant insects. An insect’s body size is determined by the proportion of oxygen in the atmosphere.
