Humans can go to space, but why can t they dive to the bottom of the sea 10,000 meters?

Although the submarine is very combat-capable, it cannot dive to 10,000 meters below the surface. And whales can do it, why is that?

Although the nuclear submarine is currently the most deterrent deep-sea ** built by mankind, it is still powerless in the face of the deep sea, because most nuclear submarines cannot withstand the huge pressure of the deep sea. However, in nature, there is a magical creature that can freely travel through the deep sea area, and they are whales. There are many species of whales, but the average species of whale can only move around 500 meters above the surface, and their lives are threatened by the pressure of the deep sea.

The reason for this lies in the internal difference between whales and submarines. We all know that once a submarine is developed, all its parameters are basically finalized, such as total mass, total capacity, ability to withstand pressure, and so on. However, some studies have found that whales, an amazing animal, are able to respond differently to environmental changes.

They adjust their internal structure according to the pressure of the external environment, so that the pressure difference between the inside and outside is not too large. They usually balance the pressure inside and outside by changing the size of their lungs, which is why whales in the deep sea have much smaller lungs than they normally would. Biologists attribute this amazing ability of whales to the result of their long-term evolution, perhaps they were not adapted to life in the deep sea at first, and as they continue to overcome the pressure of the deep sea, whales have acquired the ability to cope with difficult environments, which makes us have to marvel at the magic of nature.

Of course, scientists are aware of the peculiarity of whales and are already working on submarines. They wanted to reinvent the submarine by mimicking the inner workings of a whale, so that the new submarine could cope with the pressures of the deep sea with the same ease as a whale. However, this is not easy, and there has been no substantial progress in technology.

But many scientists believe that since nature is capable of creating such amazing creatures, humans are also capable of creating similar objects.

From ancient times to the present, human beings have learned a lot from living things, and applied these things to scientific and technological inventions, which we call "biomimetic ability". Humans do not yet fully understand nature, which means that there is still a lot of room for human beings to develop science and technology.

Because there is atmospheric pressure on the seabed, the greater the air pressure. The higher the air pressure, the worse the person's performance. Can be life-threatening.

Human beings always have the instinct to explore nature, and the universe and the deep sea are places of curiosity for us. Humans have explored the universe at an astonishing speed, and so far, 12 people have left footprints on the moon, which is 380,000 kilometers away. But in comparison, human exploration of the ocean has been very slow, with only a few people diving to a depth of 10,000 meters.

What is the horror of 10,000 meters under the sea? Why is it so slow to explore the oceans?

According to our normal thinking, the ocean is vast, but it is at least above the earthPeople should be exploring the oceans much faster than exploring the universe beyond Earth, but practice has shown that this idea is wrong。A large part of the reason why we have been able to explore the universe so quickly is that space is very similar to a vacuum, and the degree of attenuation of electromagnetic waves in the vacuum is very small.

Therefore, a single astronomical telescope is enough to detect the movement of galaxies billions of light-years away, so that the detector can be under no pressure in space。However, compared to the universe, the main component of the ocean is extremely unstable substances such as seawater, so whether it is electromagnetic waves or the detectors of some entities, they will be affected in the ocean much more complex than the universe.

In addition, because the sea water has a very strong pressure, if a person is directly exposed to a depth of 10,000 meters under the sea without wearing any protective measures, then his body will be subjected to more than 2,000 catties of pressure per square centimeter. By this calculation, the total pressure on his entire body was enough to squeeze him into a meatloaf in an instant. And the professional manned submersibles made with the help of modern science also have extremely complex processes.

According to some biologists, humans can only dive to a depth of about 100 meters without the use of any protection, but scientists have learned that most humans have an average level of body composition。In the Guinness Book of World Records, the actual depth is deeper, but only 113 meters, compared to the average depth of the Pacific Ocean of 3,957 meters, with a maximum depth of 11,034 meters. In fact, we all know that if you want to dive deeper, you need to design a special submersible.

Although we have reached 10,000 meters under the sea, we have only three successful records, and there is still a long time span, and the endurance is still relatively poor. We still have a long way to go to learn about the more wonderful ocean areas, and we still have to maintain the strength and perseverance to explore.

There will be a lot of ** fish, and there will be some shipwrecks. At present, human exploration of the deep sea has not stopped, and there will be many dangers in the deep sea, and even the explorers will be very afraid, so it will be very difficult.

There are some marine creatures, the depth of the ocean is already very deep, and there are very few researchers who have been to such a deep place, because there is huge pressure under the deep sea, so there is no way to explore, and the level of science and technology has not yet reached this point.

We don't really know what is at 10,000 meters under the sea, because we can't dive to 10,000 meters below now. Of course, technology is still developing, and it will definitely be explored in the future.

It can be analyzed in this way, because the weight of the water is large, the deeper the water level, the greater the water pressure, not to mention human beings, even if it is a nuclear submarine, the shell material is resistant to high pressure, otherwise, it will be crushed by the water.

The pressure of 10,000 meters of seabed is huge, equivalent to one ton per square centimeter, and such a large pressure is simply not able to withstand ordinary materials, so it is impossible to dive to this depth.

Too much air pressure is close to 0.

A person normally lives at a pressure of 1 atmosphere.

1 atmosphere is equivalent to 10 meters of water column pressure.

10,000 meters is equivalent to 1,000 atmospheres.

It can be seen that people only need to overcome 1 atmosphere difference in space to get to space. To 10,000 meters below the surface of the water there is a pressure difference of 999 atmospheres to be overcome.

The answer is obvious!

The farther away from the earth the atmospheric pressure becomes, the pressure increases exponentially for every 1 centimeter of drop underwater, and there is no better technology to solve the problem of pressure.

People are light and fluttering in the sky, and when they go to the bottom of the water, they have to bear the pressure of water, you can imagine how much pressure the water is at a height of 10,000 meters!

Because although there is no oxygen in space, the air pressure will not threaten human life, and the seabed is different, the seabed current pressure is too great, which directly threatens human life, and people have not yet reached the bottom of the sea, and they have long been crushed to death by the current pressure.

It can be analyzed in this way, because the weight of the water can be analyzed in this way, because the weight of the water is large, the deeper the water level, the greater the water pressure, not to mention human beings, even if it is a nuclear submarine, the shell material is resistant to high pressure and strength, otherwise, it will be squeezed out by the water. The amount is large, the deeper the water level, the greater the water pressure, not to mention human beings, even if it is a nuclear submarine, the shell material is resistant to high pressure, otherwise, it will be crushed by the water.

10,000 meters of pressure on the seabed, 1,000 tons per square meter.

The deeper the seabed, the greater the pressure, and it is impossible to say the maximum pressure.

At present, the world record for diving without equipment is about 120 meters, and the record for diving with equipment is 332 meters, and the difference between the two records is 90 times and 30 times respectively from the seabed of 10,000 meters. It is impossible to dive to 10,000 meters naked, but it is possible to take a manned submersible.

10,000 meters underwater is equivalent to 1,000 atmospheres, but it is still possible to sit in a submarine, and several countries already have deep-sea submarines of this strength; It is definitely not possible to go down naked, and if you don't do it, the internal organs can be pressed out. Human respiration depends on the pressure inside and outside the body, the lungs can expand and contract under the action of respiratory muscles and thoracic cage, and the increase or contraction of the volume of the lungs is caused by the shrinking or increasing of the gas pressure in the internal cavity, and the atmosphere enters the lungs under the action of pressure. At the bottom of 10,000 meters, the pressure is very high, there is such a large cavity in the human body, and it cannot be adjusted freely, and the ability to hold breath is also limited.

The only place in the world with a water depth of more than 10,000 meters is the Mariana Trench, and there are currently more unmanned submarine detection studies in this place, and the number of successful manned submersibles is less. China has used unmanned submarines to detect, but for manned small submarines, China seems to have only explored more than 7,000 meters at present, and is the fifth country in the world to master the technology of large-depth manned deep diving after the United States, France, Russia and Japan. However, the strength of the United States is still the first echelon, and the great director James Cameron once successfully dived to the Mariana Trench in a deep-sea diving gear built by himself, and was the first person in the world to dive in his personal capacity.

Although this depth is very large, for the marine creatures that live there, the feeling of such pressure may be equivalent to the atmospheric pressure we are experiencing, those marine creatures have high water content, and many of them do not have inflated cavities in their bodies, which are used to fight against water pressure, and water is difficult to be compressed at room temperature.

No. Because the pressure at 10,000 meters underwater is very high, and the human body cannot withstand such pressure and will be flattened, so humans cannot dive to 10,000 meters underwater.

Human strength alone cannot be achieved. The two biggest obstacles when diving are oxygen and water pressure, the amount of oxygen consumed in the 10,000-meter dive is huge, and the strong pressure from the depth of 10,000 meters will directly flatten the person.

Gravitational attraction is the attraction of two objects to each other.

The greater the mass, the greater the gravitational pull, so the sea water is heavier, the gravitational pull is stronger, the sea water will not run out, but the atmosphere will escape from the earth because the mass is too light.

Things on the earth fall to the ground because of gravity, the earth attracts objects to the surface of the earth, the earth does not have a so-called ground in space to attract it, there is no so-called up and down, everything in the universe is suspended, only the attraction between different stars.

The greatest attraction to the Earth is the Sun, and the Earth is not attracted to the Sun because the Earth has a velocity, like an object tied to a rubber band in a circular motion.

Humans are not yet able to reach the deepest part of the ocean floor, because the deep sea is super stressful and the light is insufficient, which is much more difficult than exploring space.

According to the data, at a depth of 10,000 meters at the bottom of the sea, the pressure per square centimeter can reach 1,100 tons, which is equivalent to putting 3 tanks on your fingers. In addition, if you go into the water with a person, you have to ensure that the pressure and temperature in the dive chamber are at a normal level, which is very difficult for today's technology, and it is not possible to guarantee safety.

In addition, there are many mysterious creatures on the bottom of the sea, and there are unknown dangers, and 10,000 meters under the sea is very terrifying. Not only mysterious creatures, but also surging magma and erupting volcanoes at the bottom of the sea, which can threaten diving machines and people at any time. So humans don't explore the deep sea.

The Mariana Trench, the deepest point under the ocean that has ever been explored, has not been visited by any instrument. Its depth is -11034 meters. In 1960, the American submersible Trieste dived to a depth of 10,916 meters, and no machine has broken the record so far.

At the current level of technology, human beings have not yet reached the deepest part of the ocean floor.

The deepest part of the seabed is located in the Fichaz Abyss of the Mariana Trench and is -11034 meters. So far, the deepest human dive was created by the American Trieste submersible in 1960 at a depth of 10,916 meters.

Expand: There have been two times in human history when a total of three people have descended to the deepest part of the Mariana Trench. The first was in 1960, when U.S. Navy Lieutenant Don Walsh and Swiss engineer Jacques Piccard piloted the USS Trieste to achieve the first human dive to 10,916 meters in the Mariana Trench.

However, they went on an expedition, and after staying for less than 20 minutes, the mud raised from the bottom of the sea did not disperse, and they came up without taking a picture.

Another time was in 2012, the famous Hollywood director James Cameron took the "Deep Sea Challenger" and successfully dived to 10,908 meters in the Mariana Trench. He wanted to go down and make a movie, but due to a malfunction of the equipment, he returned to the surface with nothing to do.

Even the most advanced instruments have not been developed, and the deeper the pressure, the greater the rocket propulsion.

The deepest part of the seabed is not yet reached, and the submarine cannot withstand the pressure of the depths.
