Your next black hole picture is a time warp
Around black holes, extreme spacetime warping means a single image combines emissions that originated from their source at various times. Physicists Daniel Rojas-Paternina and Alejandro Cárdenas-Avendaño show when these hidden time differences matter. Their work could help with next-generation observatories like the Black Hole Explorer, aiming to probe subtle features such as photon rings.
