Why is it true that whales can dive to the bottom of 10,000 meters and submersibles can only dive a few hundred meters?

I do not know when, there is a saying circulating on the Internet that whales can dive to the bottom of 10,000 meters, but in addition to special diving equipment, in ordinary submarines, if the dive depth of fewer than one thousand meters, the depth of 10,000 meters will be crushed.

Is this the case?

What is the pressure of 10,000 meters deep sea?

As we all know, the highest point of the earth is Mount Everest, 8848 meters high, and the deepest part of the earth is the Marjara Trench, about 11,000 meters deep.

At such a depth, the biggest threat is the pressure of seawater. For every 10 meters of dive, there is an increase of about one atmosphere of pressure. When the depth reaches 10,000 meters, it increases by 1,000 atmospheres.

One atmospheric pressure is equivalent to 10,000 kilograms, or 10 tons of force acting on a square meter, while 1,000 atmospheric pressure is like 10,000 tons of force acting on a square meter, just like a fingernail cover size to withstand nearly a ton of force.

Imagine, under this pressure, the body and fetus of any large creature can not withstand such a large force, unless it is an indestructible body.

Is there life in the deep sea?

A long time ago, it was thought that the deepest part of the Marjara Trench should be dead because no living creature could survive under such tremendous pressure.

However, nature played a joke with man. With the advancement of human technology, the depth of diving is getting deeper and deeper, but wherever humans go, they find some creatures there, including fish.

China's "Haidu No. 1" photographed 10,000 meters of underwater fish.

The discovery of fish at a depth of 10,000 meters has made scientists curious about how these creatures and fish resist such tremendous pressure and swim at the bottom of the sea.

After research, it was found that to adapt to the underwater environment, the bones of these creatures became very soft and bendable, the muscles were particularly tough, and the fibrous tissue became very dense. The most important thing is that a layer of fish skin on the body has undergone special evolution, like a protective film covering the fish, so that the fish is full of water so that the internal and external pressure has reached a wonderful balance.

The fish at the bottom of the sea certainly can survive at the bottom of 10,000 meters, but this ability is not available to any species, including whales.

Can whales dive to a depth of 10,000 meters?

Because of their thick skin and special body structure, whales are rare divers. Most whales dive to depths of a few hundred meters, with sperm whales being the most powerful divers.

People once spotted a sperm whale diving at a depth of 2,200 meters in the waters near Lisbon, the capital of Portugal. No matter how deep it was, humans never found its track. As to whether the depth of 2200 meters is the limit of sperm whale diving, is still to be discovered later.

But what is certain is that it is certainly less than 10,000 meters deep at the bottom of the sea. Pressure aside, one of the main characteristics of the whale is that it is not a fish, but a mammal.

The biggest difference from a fish is that it needs to breathe in the air or it will drown in the sea, which is the biggest irony for a whale living in the ocean, isn't it?

Depending on the size of the body, the average whale takes about 10-90 minutes to breathe. Take China's latest generation deep-sea submersible "Hai Du 1" for example, its deepest dive depth is 10,908 meters. The whole process takes 8 hours, including diving, working, and recovery. Most of these 8 hours are diving and recovery, so let's say 6 hours.

Even if the whale's speed is cut in half, it still takes 3 hours. This time also makes it impossible for the whale to ever come back, so the whale can't dive to a depth of 10,000 meters anyway.

Will the submersible be crushed at 10,000 meters depth?

It's true. In foreign countries, there was such a science column that did an experiment, which was to pump the inside of the tanker into a vacuum, and the tanker was instantly crushed under atmospheric pressure.

This is just an atmospheric pressure force. Imagine how much 1000 atmospheres of pressure would be in the deep sea below 10,000 meters.

Considering the practicality, the interior of the submersible needs a huge space to accommodate more equipment and space for human activities, and the interior space cannot be sacrificed to enhance the pressure resistance like the submersible for scientific research.

General submarines dive 500, and 600 meters and their excellent diving ability is about 800 meters, which will not exceed 1000 meters, that is, dozens of atmospheric pressure.

This is because of the characteristics of submarines. The most important thing about submarines is their stealthiness, which allows them to approach their opponents silently. Of course, the deeper they dive, the more concealable they are and the harder they are to detect.

However, an emphasis on dive depth will undoubtedly make development more difficult and increase the risk factor for insiders. The technology tree, if developed differently, can also achieve the effect of concealment, safer and less costly. That is, to reduce the submarine underwater noise, making it difficult for the enemy to find themselves, but also to achieve the effect of concealment.

For these reasons, countries do not consider the diving depth in the development of submarines but reduce the underwater noise to make it difficult for their opponents to detect them. A few years ago, there was an event that had a lower probability than a comet hitting the earth.

The French submarine, because of its advanced technology and excellent silent technology, both sides did not find each other, which eventually led to the "submarine collision" event, the rest of the people of other countries are white eat melon!

Conclusion:

Therefore, it is a rumor that whales can dive 10,000 meters to the bottom of the sea, which is not credible. Although the submersible is made of steel, it will be crushed if it goes to the bottom of the sea for more than 10,000 meters.
