How Deep Can We Go? ›

In 1960 the bathyscaph Trieste, carrying two men, set a world record by diving to the bottom of it. The onboard systems indicated a depth of 37,800 ft (11,521 m) but this was later corrected to 35,813 ft (10,916 m) by taking into account variations arising from salinity and temperature.

While there's no precise depth at which a human would be 'crushed', diving beyond certain limits (around 60 meters) without proper equipment and gas mixes can lead to serious health issues due to the pressure effects on the body, including nitrogen narcosis and oxygen toxicity.

Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth.

How deep can humans go into the earth? Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 meters (40,230 ft) in 1989 and still is the deepest artificial point on Earth.

Originally Answered: Is there an possible way for a human to survive being in the ocean 25000 feet deep? Yea, its called inside a submersible that can survive at those depths… outside of it, there is no hope for the human.

Air / gasses in the body would compress significantly, if not allowed to exit the body. Your lungs would collapse in an instant, and your chest cavity would collapse on itself, until all air has escaped, and then replaced by water. Your ear eardrums would also rapture in an instant.

Light may be detected as far as 1,000 meters down in the ocean, but there is rarely any significant light beyond 200 meters. The ocean is divided into three zones based on depth and light level.

Despite its size and impact on the lives of every organism on Earth, the ocean remains a mystery. More than 80 percent of the ocean has never been mapped, explored, or even seen by humans. A far greater percentage of the surfaces of the moon and the planet Mars has been mapped and studied than of our own ocean floor.

The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.

Realistically, we will never get anywhere near the Earth's core. The levels of heat, pressure and radioactivity (one of the main sources of internal heating) are so high that even if we could bore through over 6,000km of rock and metal, a probe would be unable to survive.

Can we dig past the Earth's crust? ›

Unlike your childhood fantasy, the scientists don't have any ambitions of boring a tunnel all the way through the planet. That probably isn't even possible, since the enormous heat and pressure inside the Earth would make crawling down such a passageway impossible, even if it somehow didn't collapse.

Beyond a certain point, which is around 12.2 km or 7.6 miles deep, the temperature and pressure become so high that they exceed the limits of human technology and engineering. At these extreme temperatures and pressures, rocks and materials within the Earth behave differently and can even melt.

That's right – you can dive to the depths of the ocean and see for yourself the Titanic. OceanGate Expeditions, a company made up of undersea explorers, scientists, and filmmakers offers the once-in-a-lifetime opportunity.

The bathypelagic is between 3,300 and 13,100 feet (1,000 and 4,000 m) beneath the ocean surface. It is an area void of light (called aphotic) and at 39 degrees Fahrenheit (4 degrees Celsius), it is very cold.

At the depth of Titanic, about 2.4 miles down, the pressure is over 3700 pounds per square inch. This colossal force would crush the human body instantaneously, compressing the air in the lungs and ultimately causing implosion.

The Physical Implications: The Crushing Pressure

At the depth of Titanic, about 2.4 miles down, the pressure is over 3700 pounds per square inch. This colossal force would crush the human body instantaneously, compressing the air in the lungs and ultimately causing implosion.

A diver at 15 feet of saltwater, typically, can stay indefinitely with almost no chance of decompression sickness while a diver at 60 feet can only remain for about an hour before needing to stop and decompress prior to direct return to the surface.
