A new video is causing seismic waves on social media, revealing the horrifying reality of what would happen if the Earth lost all its oxygen for just five seconds.
Most humans can hold their breath for that long, but if this important gaseous element were to disappear, the world would be thrown into chaos.
While some outcomes will come as no surprise to many, such as the loss of the earth-protecting ozone layer, the prolific TikTok user who detailed this hypothetical doomsday scenario dropped some surprises. I did.
For example, even if the sun were still shining on our planet, such a fast-paced catastrophe would not occur at all, because the world would turn into complete darkness.
A new video is making waves on social media, revealing the horrifying reality of what would happen to Earth (above) if it lost all its oxygen for just five seconds. Most humans can hold their breath for that long, but the world would be thrown into chaos if this vital gas disappeared.


According to @mulligan.tv on TikTok, most humans can hold their breath for this long, but the fast-paced catastrophe that would befall the oxygen-deprived planet would be hard to see as the world would turn pitch black. It is said that the possibility of doing so is low.
“At first, your body probably won’t notice,” says Thomas Mulligan. @mulligan.tv on the platform.
“But you’ll notice when the sky becomes completely black,” Mulligan added. “This is because there is no oxygen in the atmosphere to scatter the rays from the sun.”
Originally from Vancouver, Canada, Mulligan is primarily known for his videos about space, technology, the future, and famous scientists such as Albert Einstein and Carl Sagan.
As of this writing, the 20-something has amassed around 963,000 followers on the platform, intrigued by his short explanations and scientific trivia.

Any mode of transportation that relies on combustion “will immediately cease functioning,” the TikToker pointed out. And even more deadly, “the ozone layer will also disappear and everyone will start the cooking process,” he said.
Mulligan, who has made videos about how to actually survive a zombie apocalypse and the Kardashev scale of advanced alien civilizations, revealed the secondary effects of massive oxygen loss on Earth.
The TikToker pointed out that “any form of transportation that relies on combustion will immediately cease functioning, resulting in planes falling from the sky and millions of cars being disabled.”
And even more deadly, “the ozone layer will also disappear and everyone will start the cooking process,” he said.
In this new state of total darkness, humans will only feel and hear the widespread, earth-shaking effects, but soon the entire world’s population will lose another sense, Mulligan said.
He explained that the human eardrum would explode due to the change in atmospheric pressure that occurs in a vacuum where oxygen disappears.
But perhaps the biggest surprise in this scenario, at least according to Mulligan, is that the planet itself will rapidly begin to shrink and implode from beneath its crust.
His reasoning includes a bit of geochemistry and plate tectonics.
“The Earth’s crust is made up of 45 percent oxygen, so the Earth’s crust will also completely collapse,” Mulligan told his TikTok followers.
“Everyone and everything will soon start falling toward the center.”
