Dark secrets of the deepest part of the ocean

We all know that the deepest part of the ocean in the world is located in the Mariana Trench in the Western Pacific Ocean. But what makes this body of water particularly unique is that it's the only place on Earth where there is absolutely no light, with a maximum depth of 36,070 meters (approximately 11 miles). That better explains why scientists are only just now beginning to understand how the deepest part of the ocean works; It's extremely difficult to study something when everything you see is black.

Scientists now believe that there are many different layers down below—the first being about 30,000 meters deep and collapsing into a second layer for 1,000 meters.

When a diver is put in the Mariana Trench, his or her light-emitting organs are dying, ultimately making diving into the deepest part of the ocean very dangerous; Scientists at Stanford University have estimated that over time, 95% of deep-sea animals lose their eyesight.

The part of the ocean blood has been called a "Dark World" because it's pitch black and so hot that even Scuba divers can't stay submerged for more than 15 seconds; one reason is that there's no oxygen and so all the metals turn into a dark mess. And to make matters worse, there's also little light from bacteria in these dark depths, as well as an absence of food due to the enormous pressure.

As a result, scientists believe that there are really only two things that live in the "Dark World": bacteria and worms.

On top of all of this, there's another layer down below called the "Elephant's Trunk", which is about 5,000 meters deep. Experienced divers have reported that it is blacker than coal smoke and so filled with sediment; Deeper than the "Dark World" is the third layer named the "Devil's Sea", which can be reached by some extreme ocean currents.

Is there a possibility of an unknown predator lurking in this "Dark World"?

Scientists believe that there may be a "specialized" species of squid living in the deepest part of the ocean; however, they don't have enough evidence to confirm this theory as there has never been an expedition in this region before.

Another popular theory is that the deepest part of the ocean is home to a long-gone civilization; it's said that an ancient and intelligent species used some advanced technology to create some sort of "super energy source" so they could travel around and colonize other areas on Earth. And now, after millennia of the passage of time, their human descendants have died off or submerged into the surrounding environment.

Experts believe that the deepest part of the ocean is far from being fully explored as there are still many secrets to be told. The largest mystery is also its total depth, as scientists have still been unable to find out where it ends. It's possible that it could extend endlessly into a massive black hole.

The deepest part of the ocean is far from being fully explored? What secrets are hidden in the deepest part of the ocean? What creatures are hiding at this remote place on Earth? If you want to know more about this mysterious oceanic region, please stay tuned for further updates.

What's next?

Like I mentioned before, this is very difficult to study because it's so dark and you can't see much; there have only been two expeditions into the depths in the past, with a total of 47 divers taking part.

There's also another interesting reason not to go too deep: Divers are getting more and more ill down there. For example, they feel extremely tired after swimming for just three minutes; During their decompression, they're getting an uncontrollable urge to vomit. Also, many of them are developing skin conditions like rashes or lesions that never go away no matter how many days they spend at sea.

So, what is the cause of these symptoms?

In fact, science has just begun to understand this and there's a lack of medical knowledge about it at the moment; In 2003, when a scientist called Thea Hauer and her husband went down into the Mariana Trench, they experienced the same symptoms. Then in 2013, she founded a research team called the "Ocean X Team". They were supposed to return to explore the deepest part of the ocean again. However, in 2014 and 2015, both expeditions failed because their sponsors couldn't afford it due to an oil price slump. In addition, some scientists have refused to go with them because they believed that their lives were endangered by the deep sea.

Eerie sounds heard in Mariana Trench.

They announced that some strange and never-heard-before sounds were heard repeatedly in the deepest part of the ocean. Some scientists believe they're coming from animals or organisms living in the depths, while others think it could be some kind of "radioactive nuclear reaction".

As a matter of fact, there have been many mysterious sounds heard at different places around the world, such as Japan's aural phenomenon that was recorded by underwater instruments or also an unknown noise coming from Earth's core. So it's possible that these sounds are related to this place.

In other words, we lack understanding about this oceanic region; however, soon we hope to clarify these mysteries once again.
