My mind was totally blown when I listened to @Radiolab’s “Speed” episode yesterday, in particular when they discussed Lene Vestergaard Hau’s experiment — over a decade ago! — where she slowed down & ultimately stopped a light pulse.On twitter.com

Not only did she & her team stop it, they made a “matter copy” (imprinting the light on atoms), which they moved to a new location and then turned back into light. 🤯Permalink On twitter.com

She discussed the possibility of putting light on a shelf, which is just bananas. She even discussed being able to take it with you, perhaps on a flight from one location to another.Permalink On twitter.com

On the podcast they joked about going through TSA with light in a bottle, but my immediate thought was WTF would happen when they hit the bottle of frozen light with an x-ray?Permalink On twitter.com

I am both fascinated and a little terrified to be honest. Anyway, if you want to listen to that part of the episode: wnycstudios.org/podcasts/radiolab/segments/267126-master-universe See also: youtube.com/watch?v=-8Nj2uTZc10Permalink On twitter.com
