Has anyone ever reached the bottom of the ocean?
On 23 January 1960 , two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench
Is there anything deeper than the Mariana Trench?
The deepest place in the Atlantic is in the Puerto Rico Trench, a place called Brownson Deep at 8,378m. The expedition also confirmed the second deepest location in the Pacific, behind the Challenger Deep in the Mariana Trench. This runner-up is the Horizon Deep in the Tonga Trench with a depth of 10,816m.
At what depth will water crush you?
Human beings can withstand 3 to 4 atmospheres of pressure
How deep can a human dive before being crushed?
Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.
Why can’t we go to the bottom of the ocean?
“ The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it, the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch. If you went up into space, above the Earth’s atmosphere, the pressure would decrease to zero.
What would happen to a human at the bottom of the ocean?
The pressure from the water would push in on the person’s body , causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse. ... The nitrogen would bind to the parts of the body that need to use oxygen, and the person would literally suffocate from the inside out.

Can you fart while diving?
Farting is possible while scuba diving but not advisable because: ... An underwater fart will shoot you up to the surface like a missile which can cause decompression sickness
What happens to a human body at crush depth?
Since your body’s internal pressure is so much less than the ambient pressure, your lungs would not have the strength to push back against the water pressure. At a deep enough level, the lungs would collapse completely , killing you instantly.
Can you dive to the Titanic?
You cannot scuba dive to the Titanic due to its depth at 12,500 feet . Air consumption: one standard tank lasts 15 minutes at 120 feet. Supply for 12,500 feet would be impossible to carry even with a team. The deepest dive on record with special equipment, training and a support team is 1,100 feet.
