— Physicists have discovered that the ring of photons orbiting a black hole exhibits a special kind of symmetry, hinting at a deeper meaning.The photon ring, which glows orange in this visualization of light flowing around a black hole.

— When photons hurtle toward a black hole, most are sucked into its depths, never to return or gently deflected away. A rare few however skirt the hole making a series of abrupt U-turns.

— Some of these photons keep circling the black hole practically forever. Described by astrophysicists as a“cosmic movie camera” and an “infinite light trap,"the resulting ring of orbiting photons is among the weirdest phenomena in nature.
