How Fast Is Light in BEC?

17.0 m/s
61.2 km/h · 38.0 mph

In 1999, physicists slowed light to just 17 m/s through an ultracold Bose-Einstein condensate — walking pace, no faster than a flamingo flying. Lene Hau's experiment won her a Nobel Prize and opened up new ways to store and manipulate information using photons.
