Much of it remains to be discovered, like another world Underwater, what we can say has been mysterious and interesting for many of us.

Have you ever dreamed of living underwater and how it is possible? We’re not talking about being underwater for a few hours, we are talking about “living” there

The record for the longest time under water currently stands at 31 days, but…

For years we invented clothes and tools to stay under water for a long time. Even with the most advanced tools under water for a long time Currently 31 days.

Well under water allowing you to breathe as much as you want What would the situation be like if you had a car?

The device called “ExoLung” completely eliminates the problem of breathing under water.

The device called “ExoLung”, which some of you may be familiar with, works only with body power and works underwater. indefinitely It makes you stay. But don’t get too excited, with the ExoLung you can only dive to 5 meters deep, but you have to keep moving.

When you extend your legs, the tube deflates and fills with your breath. At the same time a snake rises above the water, clean Air Pull. When you pull your legs in, fresh air is directed to your nose through the hose.

It is claimed that we can live comfortably underwater with “Amphibio”, which was designed with inspiration from marine mammals.

“Amphibio,” which can be 3D printed, is a type of gill designed for humans. In current technology, a diver must wear 50 kg of clothing and equipment for 1 hour to stay underwater for 30 minutes, while Amphibio by fully packing this eliminates the problem.

However, this piece of clothing, which makes you look like a sea creature and eliminates the breathing problem, is not enough. Only at Amphibio 10 meters You can live to the depths.

As advanced as today’s technology is, there are some obstacles to life underwater.

Even if you solve the breathing problem to some extent, this is not the case. When you avoid drowning The first obstacle you encounter will be the pressure.

live at the bottom of the ocean small shrimp they may look cute, but they carry 1125 kg of pressure on those little shoulders. Moreover, they do this without even a shell.

The water pressure is at a level that can kill people in pain.

Think of the Eiffel Tower. When you reach a height of 150 meters, that’s almost half. pressure change in air you hardly notice it.

However, if you dive into water to a depth of 150 meters, your veins will collapse and your lungs will collapse. be small stuck. To avoid this, divers use weights to pull them down very quickly.

Let’s assume we dive into the water and don’t die from the pressure, we run into another problem the moment we exit the water.

80% of the air we breathe is nitrogen. When you put pressure on the human body, this nitrogen turns into tiny bubbles. tissues and blood absorbed by If the pressure changes too quickly (eg rising rapidly to the surface), the nitrogen bubbles will bubble up like soda.

As a result, the blood becomes clogged, cells remains without oxygen and the resulting pain becomes so excruciating that it is possible to pass out while in pain. Divers naturally ascend very slowly to avoid this situation and work for weeks on a smooth ascent.

We still haven’t discovered most of the oceans.

Physical barriers aside, underwater is still full of unknowns. For example creatures that live in the ocean We are not even aware of most of them.

Honestly, live underwater It seems unlikely today, but we don’t know what science will bring us in the future.

Based on what we’ve told you, do you think it’s possible to live underwater?
