How Deep Under the Sea Have Humans Gone. Almost 7 miles below the surface of the Pacific Ocean lies the worldâs deepest point, the Challenger Deep. Has anyone ever ventured there? The Challenger Deep, located in the Mariana Trench in the western Pacific near Guam, lies at a depth of 35,840 feet and could easily hold the 29,029-foot Mount Everest. The Deep was discovered in 1875, and people have been attempting to precisely measure its depth ever since.
Too much oxygen also kills, by gradually causing inflammation of the lungs over the course of a few days. We pass out when the pressure drops below 57 percent of atmospheric pressure â equivalent to that at an altitude of 15,000 feet (4,572 meters). Climbers can push higher because they gradually acclimate their bodies to the drop in oxygen, but no one survives long without an oxygen tank above 26,000 feet (7925 m). That's about 5 miles (8 kilometers) up. The edge of the known universe lies some 46 billion light-years farther afield.
