Black Hole Light Ring: Unstable Orbits and Lyapunov Chaos #shorts

[00:00:00]What if a light ring around a black hole isn't stable, but tries to escape forever? Imagine photons circling near the event horizon, perfectly balanced for a moment, then suddenly slipping into chaos. Here's the twist. The orbits are unstable, so tiny nudges grow fast, like a butterfly effect, and the system's Lyapunov chaos rate tells you how quickly.

[00:00:23]That's why the brightness flickers, and why shadows look sharp, but unpredictable. Want more wild physics in seconds? Subscribe now.
