In one minute
Philbin, Leonhardt and colleagues build on the fact that an event horizon behaves like waves in a moving medium: a horizon forms wherever the medium moves faster than the waves. Their picture is a river flowing towards a waterfall, where beyond some point waves can no longer travel upstream. Using ultrashort pulses in microstructured optical fibres, they demonstrate an artificial event horizon made of light. They observe a classical optical effect, light blue-shifting at a white-hole horizon. Theoretical calculations show the same system can probe the quantum effects of horizons, in particular Hawking radiation.
