How do you steer a 10,000-ton nuclear submarine through a pitch-black underwater canyon without GPS, without windows, and without crashing?

In this video, we explore the mind-bending physics of underwater inertial navigation. From the devastating crash of the USS San Francisco to the exact calculus of integration drift, discover how engineers solved the "blindfold paradox." Learn how Earth's curvature required the invention of an 84.4-minute simulated pendulum, and how modern navies use quantum physics, laser ring gyroscopes, and the Sagnac effect to navigate the deepest oceans completely undetected.
