Black Hole Photon Sphere Chaos: Lyapunov Instability Explained #shorts

Ajouté : 2026-06-02

[00:00:00]What if light could fall into a black hole, but also orbit forever in a perfect shell? Here's the chaos at the photon sphere. Photons can circle, yet any tiny nudge makes them diverge.

[00:00:10][music] That's Lyapunov instability. Instead of returning to the orbit, [music] the path stretches away exponentially, like a butterfly effect for light. So, the sphere isn't stable at all. It's just balanced on a knife's edge.
