This is a YouTube video titled "Did you know that we are more familiar with the surface of Mars more than we know our oceans? 🌊" (created 2025-12-04T16:15:01+00:00). The excerpt is a short dialogue between two participants labeled SPEAKER A and SPEAKER B discussing differences between air/space and underwater environments, noting we understand up to ~1,000 feet, contrasting electromagnetic (light-speed) remote/satellite communication in air with acoustic (sound-speed) communication underwater, and highlighting the role of onboard artificial intelligence for underwater operations. It reads like an interview or panel excerpt about underwater physics, communications, and robotics.

There goes a saying that we know the surface of Mars more than we know our oceans. As we go from aeroplanes to jets to space shuttles, the air becomes thinner and thinner, less and less resistance as you go up. But as you dive down, water becomes thicker and thicker. Anything to rotate, anything to move, anything to send signal and receive the signals is definitely a whole lot of physics.
Completely agree with you, but you are saying that you operate up to 1,000 feet. We understand up to 1,000 feet pretty well. What's the competitive dynamic like?
The communication out of the water is simply by remote. In the speed of light, electromagnetic waves, that is how fast a remote operates, how fast a satellite can be operated. In water, it is at the speed of sound. If anything happens underwater, there's a whole lot of artificial intelligence, onboard intelligence that goes into it.
