Explorer Victor Vescovo shares how he engineered a sub to reach 35,000 feet below the sea and what he's discovered in Earth's deepest trenches.

What We Discuss with Victor Vescovo:

• Victor Vescovo led the Five Deeps expedition, becoming the first person to reach the deepest points of all five oceans. Prior to his expedition, several of these locations weren't even precisely mapped, requiring extensive sonar surveys to locate the actual deepest points.
• The average place on Earth is 4,000 meters underwater, and 71% of Earth is ocean — of which 75% remains completely unexplored. This means about half of our planet is still unexplored, and in many respects, we know more about the surface of Mars than our own ocean depths.
• The high pressures present at the deepest ocean points required innovative engineering solutions to navigate, including a perfectly spherical titanium pressure vessel that actually became stronger with repeated dives due to the intense pressure "reforging" the metal.
• Beneath 6,000 meters, the ocean is a sunless realm of absolute darkness. But even here, life thrives beyond the reach of light under pressure that would crush the average surface dweller, hinting at the flora and fauna we might expect to find on even the most extreme alien worlds.
• Anyone can become an explorer and push technological boundaries by breaking down seemingly impossible challenges into smaller, solvable problems. As Victor demonstrates, by carefully analyzing requirements, building the right team, and maintaining disciplined program management, even the most ambitious projects can be achieved through methodical execution and persistent dedication.
• And much more...
