Simulation shows terrifying reality of how deep the sea really is as people make shocking realisation

To find out that the deepest known point in the ocean is around 10,935 meters (35,876 feet), frankly, isn't that interesting.

However, viewers have been left stunned after YouTube channel MetaBallStudios shared a 3D animation of the deepest part of the ocean, using the depth of different lakes and seas.

One person called the video 'an absolute masterclass in cinema storytelling' as it demonstrates the deepest known point located in the Mariana Trench in the Pacific Ocean.

Watch below:

Called 'Challenger Deep', it sits in a long and narrow area which is deeper than Mount Everest is tall.

For context, the peak of Mount Everest is around 8,848 meters (29,026 feet) above sea level.

One viewer commented: "The deepness is scary. Imagine going out over the deepest point of the Mariana Trench and jumping into the water and just floating for a few minutes.

"Hell no. You are closer to an airliner flying above you than you are to the bottom below you."

"The human mind really isn't built to be able to comprehend these kinds of numbers very easily, but your presentations bring it all into perspective," a second penned.

"When I first heard the deepest part of the ocean is 11km deep it didn't seem like much," a third added.

"But when I started watching videos about the ocean, the pressure, the unusual species, it kept getting terrifying. An 11km straight dept into nothing but water is actually unimaginable."

Journalist James Nestor, who is the author of 'Deep: Freediving, Renegade Science, and What the Ocean Tells Us about Ourselves', explained in his 2014 book what it's really like to be so deep in the water.

"At three hundred feet, we are profoundly changed. The pressure at these depths is nine times that of the surface. The organs collapse," he wrote.

"The heart beats at a quarter of its normal rate, slower than the rate of a person in a coma. Senses disappear.

"The brain enters a dream state. At six hundred feet down, the ocean’s pressure—some eighteen times that of the surface—is too extreme for most human bodies to withstand.

"Few freedivers have ever attempted dives to this depth; fewer have survived. Where humans can’t go, other animals can.

"Sharks, which can dive below six hundred and fifty feet, and much deeper, rely on senses beyond the ones we know.

"Among them is magnetoreception, an attunement to the magnetic pulses of the Earth’s molten core."

He noted that 'eight hundred feet down appears to be the absolute limit of the human body'.
