Cosmic Hourglass: The Flickering Shadow of a Wormhole

Numerical simulations revealed how plasma gets stuck in the throat of a rotating wormhole, painting a thin luminous rim on its shadow and making it flicker with a period set by mass and spin. These signatures, observable by the Event Horizon Telescope at 230 GHz, turn active galactic nuclei into nat
