Why would scientists prefer to explore space rather than the deep sea?

Space is as scary as the deep sea. Because of these two places, you can't always go. That is, the astronauts are in the sky, the divers are at sea, they have to make adequate preparations and do everything well.

Still, they should be mentally prepared and not be afraid of what happens. A normal person would do the same thing if they threw you into space or the deep ocean and never be seen again. About the horror of deep space.

Spatial fear is due to the inability to control and recognize the environment, things and the future, as well as the physical discomfort caused by the special environment, resulting in various bad psychological hints and emptiness, leading to a variety of uncontrollable and ** fears.

Deep-sea fear refers to anxiety, fear, and depression about a specific unknown location, leading to a variety of fearful emotions. Whether from the perspective of human psychology and body, or relative to the depth of human exploration and cognition, space is more feared than the deep sea. Since space is exotic, it can cause immeasurable damage to the mental and physical structure of people, while the deep sea and people both belong to the origin of the earth and have a certain compatibility.

According to the current exploration and practical understanding, the discomfort of the deep sea to the human body is limited to the problem of oxygen and pressure, and in order to solve the harm of the space environment to the human body, in addition to the problem of oxygen and pressure, there are cosmic radiation and many other unknown substances.

Personally, I think that it may be due to the relatively large risk factors in the sea, and the lack of relevant professional exploration equipment, there are certain technical defects, and it is currently impossible to carry out the first seabed.

Because humans cannot survive on the bottom of the sea, but they can immigrate to the planet, it is more difficult to explore the bottom of the sea.

The ocean always gives people an incomprehensible feeling, in the sea there are many creatures we don't know, for human beings, the deep sea is more like a terrifying abyss, in the sea we will feel cold, depressed and unable to breathe, the deep sea is not only stressful, but also very low temperature.

Scientists are only getting started with the study of the deep sea. When it comes to the deep sea, I don't know if you have an inexplicable fear in your heart like me. Human civilization has progressed to this day, and has never stopped exploring space and the ocean, but relatively speaking, the research of the deep sea is more difficult.

It is understood that in 2020, the Mighty successfully dived to a depth of 10,909 meters, although it is only more than 10,000 meters, but this has reached the limit, so there is still a lot of room for future research.

There must be some friends who will be curious, obviously the ocean is closer to us and seems to be within reach, why are scientists more keen to explore outer space? This is probably the realization that if the earth becomes extinct one day in the future, the chances of human migration to an alien planet are higher than at the bottom of the sea, after all, we cannot live on the bottom of the sea like fish. We don't even know what's in the deepest part of the ocean.

In addition to marine life and mineral resources, it is not known whether there are any large organisms that are already extinct.

Although we feel an inexplicable fear of the unknown, of course, human beings who believe in wisdom do not stop the pace of exploration. It is believed that one day in the future, with the progress of science, mankind will finally unveil the mystery of the deep sea and excavate more marine resources. But in the same process of exploration, we must respect the ocean and nature.

Land and sea coexist, and to protect the ecological environment of the ocean is to protect ourselves.

At present, scientists are just starting to study the deep sea, and it is very difficult to study the ocean, and the information about the ocean is only a small part of what scientists know.

At present, scientists have been able to enter Shanghai at a distance of 10,000 meters and study many deep-sea organisms, which have been sampled and studied on land.

Scientists have not studied the deep sea very well, and have not yet discovered what lies beneath the deep seabed.

Here's why:

First of all, because the deep sea is endless darkness. The sunlight in the ocean can only shine to a depth of 1,000 meters at most, and the bottom is deep darkness, and you can't see your fingers, which can directly scare claustrophobic people. And exploring space is somewhat bright.

But below 10,000 meters, there is endless darkness and silence at the bottom of the sea.

This is followed by tremendous pressure. According to scientists, the pressure ratio of 10,000 meters in the deep sea is more than 1,000 times more than the standard atmospheric pressure, which is equivalent to an area of one square meter to bear more than 1 ton of weight. So the pressure in the deep sea is also very scary.

Features of Deep Sea Terror:

The further down you go, the less life you will live there will be, because the sunlight cannot reach it, the oxygen in the depths of the ocean floor is very thin, and there are not many nutrients for the fish to survive. Due to the harsh environment of plum potatoes, there will be fewer and fewer fish, and more plankton. When you dive to 10,000 meters, all that exists is microbes.

To sum up, human exploration of the deep sea, although there has been the emergence of manned probes, but the number of people who can carry is very limited, and it is unlikely to achieve "extravehicular walking" like in space on the seabed, and the huge seawater pressure cavity disturbance will kill people when humans walk out of the probe. Deep-sea exploration is indeed more difficult than space exploration.

In fact, human beings do not know as much about the oceans on our planet as they do about space, because the technology for deep-sea exploration is actually more difficult than that of space. But the exploration of the deep sea and the exploration of space are each of their own importance and cannot be compared with each other. At that time, space and the deep sea faced very different environments.

Deep. The exploration of space mainly depends on rockets, and if the rocket technology is passed, the spacecraft.

The main problems faced by the launch process are vibration, shock and so on. These are in the product design.

In the process, considering the mechanical and thermal design is relatively easy to solve.

Space. However, if you want to explore the deep sea, you are faced with the problem of suspension control and attitude control. If the depth of the dive is shallow, a steel cable can be used.

Traction floats up and down. In this way, the range of motion is small. As the depth increases, the steel cable can break at any time, so it is not possible to dive to a depth of several kilometers.

Deep diving is currently generally done by controlling one's own density. For example, the use of electromagnets.

Pieces of ballast iron are sucked on the outside of the submersible, so that the overall density of the submersible is greater than that of seawater to achieve diving. Without the rope to be towed, how to ensure the suspension balance of the deep submersible at different depths is a big problem. Therefore, although it is only more than 10,000 meters, the diving process of the deep submersible is relatively long, and the attitude control in the middle is also difficult.

Seabed. The problem of pressure and temperature is encountered in both space and underwater. Because there is no air in space, and there is air inside the vehicle, the inside and outside of the cabin is an atmosphere.

pressure. So, let's look at the spacesuits that astronauts wear when they get out of the capsule.

It's not too thick to withstand a vacuum. Temperature differences and radiation in space need to be protected. When the vehicle is facing the sun, the temperature can reach more than 100 degrees, and when there is no sun, the temperature can reach more than -100 degrees.

In addition, various rays and radiation particles in space need to be reinforced with metal shells.

However, underwater mainly faces the dual problems of pressure and low temperature. According to the pressure conversion of the water body, basically 10 meters is an atmosphere, then 10,000 meters is 1,000 atmospheres. This is a very high pressure, and if the cabin can't withstand it, it will be crushed instantly after going down.

Therefore, the pressure-bearing and airtight design of deep submersibles is much more difficult than that of spacecraft.

Therefore, there is no concrete progress in the exploration of the deep sea by human beings, and it is hoped that one day the development of human science and technology can have a deeper understanding of the earth we live in.

With the continuous development of science and technology, people have been able to go to the sky and the sea, so have you ever thought about which is more difficult, "going to the sky" or "going to the sea"?

In recent years, we have always seen news about the successful launch of space probes, and under the detection of probes, mankind has begun to have a clear understanding of space, and the farthest probe, Voyager 1, has sailed to space 22.2 billion kilometers away from the earth, and for the ocean, it seems that there is no new progress.

However, the ocean has been known for a longer period of time than in space.

In the 8th century AD, Vikings measured the depth of the sea.

In 1930, William Bibby and Otis Barton, the originators of deep-sea exploration, made a real deep-sea dive, and in 1934 set an all-time record of 923 meters.

In 1960, the famous Swiss deep-sea explorer Jacques Picard and U.S. Navy Lieutenant Don Walsh boarded the "Trieste" deep-sea submersible and successfully dived into the Mariana Trench, the world's deepest trench, to a depth of 10,916 meters for research.

In 1872, large-scale ocean expeditions began.

As we all know, the total area of the earth's oceans is about 100 million square kilometers, accounting for about 71% of the earth's surface area, but looking at the present, in the face of such a large ocean, the deepest trench explored by human beings is still the Mariana Trench. It can be said that human civilization has only exploited 5% of the oceans so far.

Deep Sea Fear: "Heard that, right? The ocean is always unpredictable, and there are many creatures we don't know about, and for the "landlubber", the deep sea is more like a terrifying abyss. Because the deep sea always makes people feel cold, oppressive, and unable to breathe.

We all know that in the ocean, for every 100 meters of dive, there is an increase of 10 atmospheres, and for every 10,000 meters of descent, it increases by 1,000 atmospheres. A professional diver can dive to 400 meters is already the limit, and if a submarine wants to descend to a deeper place, it has to break through layers of resistance such as high pressure and water temperature. At present, the deepest part of the Mariana Trench that can be explored by mankind has reached a pressure of 100 atmospheres, which is equivalent to putting a crane of nearly 70 tons on our fingers.

In addition to high pressure, low temperatures in the deep sea are also a major problem. The place where the sun can reach is warm, and the sunlight can reach the surface of the sea, but it cannot reach the deep sea, so the deep sea is a low temperature environment.

According to experts, the water temperature in the ocean at a depth of 1,000 meters is around 7 degrees Celsius, while above 1,000 meters, the water temperature is around 0-4 degrees Celsius. Although it is close to freezing, it does not freeze due to pressure and undercurrents. Moreover, the deep sea is pitch black.

In places where light and temperature can't be touched, how terrible are the creatures that can be raised.

The places we can't explore are unknown, and the unknowns are often fearful. But human exploration of the unknown will not stop, for marine resources, we will definitely explore and excavate.

Scientists have always attached great importance to the exploration of space, and are reluctant to study what is in the deep sea. Because the deep sea is not as simple as everyone thinks, there are many scary things in it. Because many aquatic products have long relied on the ocean for survival, there is abundant energy hidden in the seabed.

Once you encounter danger while exploring the sea, it is even more terrifying than you think. Scientists don't want to risk their own lives, so they often choose to do more research in space. Because in space you can find things that you can't find anywhere else, and you can live and live in them.

Although science and technology are constantly evolving, there will still be technical limitations. The deep-sea puzzles have never been solved, and the depths are very dark underneath. It's impossible to explore it all at once, because the human eye can't compare to technology after all.

The human eye can see about 200 meters underwater, but if it is not stationary, the range will continue to expand. Scientists have to bring instruments to the sea, because some things are not waterproof. <>

Scientists haven't been exploring the deep ocean all the time, it's just slowly. The blue whale is the largest creature in the world, and scientists don't know if there is a bigger creature in the ocean. Once a giant undersea creature encounters a human, it will hunt and kill it at will.

People are naturally afraid of such sea creatures and are often reluctant to gamble with their lives. Volcanoes also occur from time to time in the depths of the ocean, which is even more frightening. <>

In general, the ocean is mysterious, but it must be studied. Because it will not only bring a variety of value to people, but also open up a different field. It is believed that scientists will always lift the veil of the ocean in their continuous exploration.

They are working on a device that can go to sea, and when they are done, they will definitely choose to make it public. It allows people to see the ocean as it is, and it is a rich experience for everyone.
