Number 10: It’s One Of The Deepest Parts Of Our World.
When you think about our world, you likely think about how far we have come in terms of building up our cities, or how high we’ve gone in terms of space travel and what not. You might even look at the oceans and wonder how deep it actually is to the bottom of the ocean. Well, as the Mariana Trench has shown us…it’s pretty deep. In fact, it’s so deep, that some think it can go even deeper than we know.
Just to reach the Mariana Trench, you have to go 36,070 feet. Specifically, you have to do it off of the nearby Mariana Islands, but the point is still there to be made. This is a massively deep trench. If you still need some context as to how deep the trench is, think about it like this.
Mt. Everest is the tallest mountain (above sea level) in the world, right? And it’s a great honor to climb all the way up there and survive, right? Well, if you were to pick up the ENTIRE mountain from tip to summit, turn it upside down, and stick it into the ocean…you still wouldn’t reach the trench. You’d still be over 7,000 feet away, in fact.
That’s how deep the Trench is. Or at least, just to reach the top of it. Which begs the question…
Number 9: How Low does it go?
That is the question, isn’t it? And to be completely honest…we have no true clue. The fact is that although we’ve sent people and probes and other devices to try and scan the depth and width of the place, there’s still no indication of how deep it truly goes.
There are actually sections of the trench, and one of them is the Challenger Deep, which is said to be the deepest part of the trench. But, because we can’t explore it at will, there’s a very good chance that there are even DEEPER parts of the trench, and by that extension, deeper parts of our own ocean.
I bet you’re getting a kind of scale vertigo, huh? Because all of this just goes to show the ocean is much, MUCH deeper than anyone could’ve imagined, which also makes it a place that humans definitely want to explore, because nothing terrifies a human scientist more than a question that has gone unanswered for an incredible period of time.
But seriously…how low DOES it go? Sorry, but, there’s just no way of knowing right now.
Number 8: Deep Trouble.

Believe it or not, we’ve known about the Mariana Trench since the 1800’s. 1875 to be exact. However, just because we knew it was there, didn’t mean that we could get to it. In fact, it took us nearly a hundred years to get something strong enough to go down there and start scanning the area.
What do I mean by strong enough? What you need to remember is that water and air are similar in many ways (not the least of which is that air makes up water in part), and because of that, they can both increase in pressure in a significant way. The deeper you go into the ocean, the more the pressure of water builds up. That’s why scuba divers can only go so far on their own. Once you get to about 400 feet below sea level, the pressures of the ocean start to grow incredibly strong, and it can severely hurt the human body. If you’ve ever heard of the Bends, it happens when a diver goes into a deep pressure zone and then quickly rises to a lower pressure zone. This causes the body to pressurize and de-pressurize too quickly, and can cause serious health issues.
If you go too far down into the ocean, you’ll literally be compressed by the pressure, and not in a fun way. Think of it like a pop can being crushed by your hand. And, though it’s never happened before to a human, in some areas, the pressure is so deep that you’d likely be crushed into oblivion…or even turned inside out. Seriously.
Fun fact, we have retrieved creatures from the Mariana Trench and attempted to bring them to the surface. Keyword here is “attempted”. Because the creatures that somehow survive in the Mariana Trench are so used to the pressures of that water that any attempt to bring them into lighter pressure areas destroys them. It’s not pretty.
Hearing all of this, you might think it’s impossible to go down to the Trench and survive…but…
Number 7: Three Explorers.
It’s has happened before. Twice actually. In total, only three people in the history of the world have ever made it to the Mariana Trench, and the trips were quite spread out from one another.
The first of these trips were done in 1960, 85 years after the discovery of the Trench.
