I don't know since when, there is a saying on the Internet, that is, whales can dive into the seabed at a depth of 10,000 meters, and in addition to special diving equipment, general submarines, diving less than 1,000 meters deep, if they reach the 10,000-meter deep sea, they will be squashed.
Is that really the case?
We all know that the highest point of the earth is Mount Everest, whose height is 8848 meters, and the deepest part of the earth is the Mariala Trench, which is at its deepest point, about 11,000 meters deep.
At such a deep level, the biggest threat is the pressure of the seawater, which increases by about one atmosphere for every 10 meters of diving, and 1,000 atmospheres when the depth reaches 10,000 meters.
An atmospheric pressure is equivalent to 10,000 kilograms, that is, 10 tons of force acting on a place of 1 square meter, and 1,000 atmospheres of pressure, like 10,000 tons of force, acting on a place of 1 square meter, just like the size of a fingernail, to carry nearly a ton of force.
Imagine that under this pressure, no large biological flesh could withstand such a great power, unless they had cultivated the incorruptible body of King Kong.

Long ago, it was thought that the deepest part of the Mariala Trench should be a dead silence, because no living thing could survive under such great pressure.
But nature has made a joke to human beings, with the progress of human science and technology, the depth of diving is getting deeper and deeper, but no matter where humans go deeper, some creatures will be found in those, including fish.

In the seabed at a depth of 10,000 meters, the presence of some fish has also been found, which makes scientists very curious about how these creatures and fish resist such a huge pressure and swim on the seabed.
After research found that these creatures in order to adapt to the environment of the seabed, the bones become very soft, can be bent, the muscles are particularly tough, the fibrous tissue has become very dense, the most important thing is that a layer of fish skin on the body has undergone special evolution, just like a layer of protective film covering the body of the fish, so that the fish body is full of water, so that the internal and external pressure to achieve a wonderful balance.
Of course, fish on the seabed have this ability to survive on the 10,000-meter seabed, but this ability is not available to any species, including whales.
Whales due to their thick skin, as well as special body structure, is indeed a rare diving expert, most whales diving depth of a few hundred meters, and among them, the most powerful diving is the sperm whale.
People have found that the depth of diving is 2200 meters of sperm whales in the sea near Lisbon, the depth of the Portuguese capital, and then deeper, humans have not found the trajectory of their activities, as to whether the 2200 meters depth is the limit of the sperm whale diving, this will be discovered later.
But what is certain is that it is absolutely less than 10,000 meters deep on the seabed, and pressure aside, a major feature of whales is that it is not fish, but mammals.
The biggest difference between it and fish is that it needs to breathe in the air, otherwise it will be drowned by the sea, which is the biggest irony for whales living in the ocean, isn't it?
According to the size of the body, the general whale ventilation time is about 10-90 minutes, to China's latest generation of deep-sea submersible "Haidou I", the deepest diving depth is 10908 meters, diving, plus work, plus recycling, the whole process takes 8 hours, and in these 8 hours, most of them are diving and recycling, counting its 6 hours.
Even if the speed of the whale is fast, cut in half, it will take 3 hours, which also makes the whale have no return, so in any way, the whale can not dive to a depth of 10,000 meters.

This is true, in foreign countries, there was once such a scientific column, did an experiment, that is, the tank truck inside the vacuum, under an atmospheric pressure, the tank truck was instantly flattened.
This is just the power of an atmospheric pressure, just imagine, down to 10,000 meters deep sea, how big will 1,000 atmospheric pressure be?
Considering its practicality, the submersible needs a huge space to accommodate more equipment and personnel, and it cannot sacrifice the internal space to enhance its pressure resistance like the scientific research submersible.
Submarines generally dive at 500 or 600 meters, and individual diving capabilities are excellent, which is about 800 meters, and will not exceed 1000 meters, that is, dozens of atmospheric pressures.
The reason for this is because the characteristics of the submarine determine that the most important thing about the submersible is its concealment, so that it is quietly close to the opponent, of course, the deeper the dive, the more concealed, the more difficult to find.
Blindly emphasizing the depth of diving will undoubtedly increase the difficulty of research and development, and will also increase the risk factor of internal personnel, and if the technology tree is developed to another aspect, the same can achieve a hidden effect, can be safer, and the cost is lower, that is, to reduce the submarine's underwater noise, so that the enemy is difficult to find themselves, the same can achieve the effect of concealment.
Based on the above reasons, in the process of developing submarines, countries are not considering the depth of diving, but reducing the underwater noise, making it difficult for opponents to find themselves.
The submarines of the United Kingdom and France, because they are very advanced, the mute technology is very excellent, resulting in neither side finding each other, which eventually led to the "submarine collision" incident, and also let the rest of the people of various countries eat a melon in vain!
epilogue:
Therefore, it is rumored that whales can dive ten thousand meters to the bottom of the sea, which is not credible, and although the submersible is a body of steel, if it passes down to the 10,000 meters deep sea, it will really be squashed.
