As far as I am aware, only two people have ever reached the bottom of the Marianas Trench. Jacques Piccard and Donald Walsh dived to 10,915 meters in a navy bathyscaphe called Trieste on January 23, 1960. I don't think this dive has ever been replicated by any manned submersibles since.

What happens to the human body at the bottom of the ocean?

Have you ever gone down in the deep end of a swimming pool? Usually is about 12-15 ft deep. Notice how hard it feels the deeper you get? Well, that's same as if you go to bottom of ocean. Deepest part of ocean is Mariana Trench, about 7 MILES deep. so if you feel lots of pressure upon you when you're only 12-15 ft deep in a swimming pool, imagine how your body would be if you were under 7 miles of ocean water. Several thousands of pressure per square INCH. Even atomic subs can only go about 1,000 feet deep before they explode from the pressure. And yet, there are creatures, animals living at the bottom of the trench. they have adapted to that deep pressure as if it's no problem whatsoever. but if we caught one and tried to bring it up to surface, it would die from LACK of pressure before it went very far upward.


What is the lowest place on planet earth?

The lowest place on Earth: The deepest part of the Mariana Trench (or Marianas Trench) north of New Guinea and south of Guam lies 10944 meters, or 35,797 feet, or 6.8 miles below the surface of the ocean. So far, that would be the lowest place you could go on earth. The lowest place on the surface of the Earth is the shore of the Dead Sea, which is 417 m below sea level. It lies on the border between Jordan and the territories of Israel and the Palestinian West Bank.


What is the deepest you can put an object in?

The deepest you can put an object into the ocean is about 36,000 feet (approximately 11,000 meters) at the Mariana Trench, specifically the Challenger Deep, which is the deepest known point in the Earth's seabed. However, practical limits for most objects are influenced by the material's strength, pressure resistance, and technological capabilities. As you go deeper, the immense pressure can crush many objects, limiting how deep they can be effectively placed.

Where are the lowest place on earth?

Your coldest water temperatures will be found at the polar regions, north pole and south pole. The South pole is covered by a continent and so you can only look at the ocean around the continent. The North pole is ice floating on water. The coldest temperature ever recorded in sea water was minus 2.6 degrees C, though on average near the north pole it's about minus 2 degrees C. The reason it's lower than zero is because sea water contains dissolved substances which lower the freezing point. If you are looking for solid water, go to the middle of the north pole and you have solid water, ice. If you include this as part of the ocean, of course it's possible for this to be colder still, depending on the weather.
