Why are many countries no longer exploring the Mariana Trench? Did you find something in the abyss?

If there is any scariest place on earth, it must be the Mariana Trench

The Mariliana Trench in the western North Pacific is the deepest place on earth, with a total length of about 2,550 kilometers and an average width of 70 kilometers.

The lowest point of the trench is called the Fichards Deep, and the depth of the ocean reaches 11,034 meters.

If measured by this depth, even if you put Mount Everest, the highest mountain on the earth, into it, it will not be able to rise above the sea.

How was the Mariana Trench formed?

The Mariana Trench was formed by the collision of the Eurasian and Pacific plates.

The Eurasian plate is a continental plate that collides and rises to form an island arc, while the Pacific plate collides and sinks to form a trench, which is the Mariana Trench.

In the depths of the Mariana Trench, it can be said that there is never sunshine. It is a terrible world of cold, high pressure and darkness, almost a forbidden area for life. Therefore, the Mariana Trench is also known as the area with the worst golf course environment.

Little was known about the Mariana Trench in the past

It was not until the development of human science and technology in the past 100 years that it began to set foot in this area.

The "Diriast" submersible, first created by scientists in the 1960s, successfully dived to a depth of 10,916 meters at the bottom of the Mariana Trench

There is a full 1100 atmospheres here. If a person stands in it, they can be crushed instantly, because the pressure per cubic centimeter is as high as 1.1 tons.

Coincidentally, in March 2012, the legendary director Zhan, who had filmed famous sci-fi movies such as "Avatar"

James Cameron, the director took the Challenger submersible alone and successfully reached the depth of the 10,929-meter trench,

Finally, he returned to the surface safely and set a new record.

Although the Mariana Trench has long been known as a restricted area of ​​life

But scientists found in deep-sea diving that life still exists in the deep-sea world with huge water pressure and oily sunlight

In the water depth of 2000~3 kilometers, groups of large-mouthed anglerfish were found, and Dumbo, octopus and deep-sea dragon fish were found in the depth of 5 kilometers.

Lionfish were even found in the ultra-deep sea at 8,145 meters, breaking the record for the highest depth ever recorded by a fish

The creatures living in these areas look very strange and terrifying, like extraterrestrial creatures

Due to the influence of the living environment, some organisms have even evolved light emitters

Not only that, but Japan's Trench also saw some white sea cucumber-like creatures wriggling on the bottom mud at 10,911, something they had never seen before.

This also shows that there is still life in the Fichards Deep. Scientists speculate that there must be many unknown creatures in the depths of the Mariana Trench that can adapt to this terrible environment.

Over the years, whether it is the United States or China, everyone's science and technology have achieved further development and breakthroughs, so why is no one further challenging the Mariana Trench now?

Why are many countries no longer exploring the Mariana Trench? Did you find something in the abyss?

The reason why the Mariana Trench is difficult to explore is not just because the depths of the trench are dark.

In the deep sea, the water pressure has reached an extremely terrifying value. Ordinary submersibles will be crushed into pieces by the huge water pressure when they reach the depths of the Mariana Trench.

This puts forward high requirements for the design of submersibles. Generally, countries do not have enough funds and technical research to explore submersibles in the Mariana Trench.

In addition, the temperature in the trench area is extremely low, the oxygen content is scarce, and the food is even scarcer. It is no exaggeration to say that it is an undersea hell.

The dark and oppressive environment at the bottom of the trench will put a lot of pressure on the explorer's psychology

Extremely prone to marine claustrophobia

And unmanned operation technology has great limitations, so countries have not continued to explore.

Although human beings are obviously very advanced now, they are still helpless in the face of the vast ocean. Therefore, sometimes we must respect nature. After all, human beings are very insignificant in front of nature.
