Researchers create black hole analog using vibrating light mirrors
Scientists at the University of California, Santa Barbara confirmed a theory about light pulses in optical cavities on November 6, 2026.
New experiment confirms old theory
David Weld and his team swapped the usual roles of light and matter to test a specific prediction. They observed that waves inside an optical cavity bunched together into short, intense pulses when mirrors moved rapidly. This behavior matches mathematical models describing light near a black hole event horizon.
Cavity mimics curved spacetime
The optical cavity behaves in ways that replicate the strange physics found in curved spacetime. Researchers published these findings in Physical Review Letters after successfully testing the hypothesis for the first time. The setup uses pairs of light-trapping mirrors to confine waves and create stable frequencies.
Mirrors drain energy one way
Vibrating one mirror at a rate matching the light round trip causes energy to flow steadily in a single direction. This one-way flow resembles conditions near a black hole or its hypothetical counterpart known as a white hole. The results validate theories that had never been directly tested before this study.
