Wormhole Shadow: Sharp Angles When Rotating ⚡ экспресс
Original: "On the Cuspy Structure of Rotating Wormhole Shadows"
A wormhole’s rotation turns its shadow into something like a gear — with sharp teeth instead of a smooth circle.

A wormhole can cast a shadow not with a smooth edge, but with sharp teeth — like crumpled paper. This shape is created by rotation and a special 'stretching' of light. This discovery will give future telescopes a way to tell wormholes apart from black holes.
🎯 Wormholes haven't been discovered yet, but Einstein's equations allow for their existence — just like black holes once were.
🎬 In Interstellar, the journey through a wormhole happened without its shadow — too bad: perhaps it would have looked like a gear.
