## How long would it take to swim to the bottom of the ocean?

about four hoursFirst off, nobody could free swim to the “bottom of the ocean.” Two reasons come to mind. First, it takes about four hours to descend in a deep sea submersible to the bottom of the Challenger Deep in the Mariana Trench. That’s the deepest point in the ocean at slightly over 36,000 feet deep. That’s 6.8 miles.

## How deep is the deepest part of the ocean in miles?

Then explain to students that the Mariana Trench is the deepest part of the ocean and the deepest location on Earth. It is 11,034 meters (36,201 feet) deep, which is almost 7 miles.

## How deep can a human dive before being crushed?

Most scuba divers won’t go deeper than 130 feet. The problem isn’t being “crushed” – it’s nitrogen gas being forced into dissolving into our tissues and then turning back into destructive and painful bubbles when you come back up again.

## What would happen if you were teleported to 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. At the same time, the pressure from the water would push water into the mouth, filling the lungs back up again with water instead of air.

## How far down is the Titanic?

## Why can’t we go deep in the ocean?

The main reason is deep sea is finite whereas Outer space is infinite. Getting humans down to the deepest areas is exceedingly difficult due to extreme pressures. All that pressure makes deep sea exploration logistically very difficult and extremely dangerous. but with use of science we overcome.

## Will Titanic ever be raised?

After several trips back to the drawing board, it turns out that raising the Titanic would be about as futile as rearranging the deck chairs on the doomed vessel. After a century on the ocean floor, Titanic is apparently in such bad shape it couldn’t withstand such an endeavor for a variety of reasons.
