Physicists have used Google's quantum computer to send a signal through a wormhole, a shortcut in space-time first theorized by Einstein and Rosen in 1935. The landmark experiment was published today in Nature. Lots to say about it. Here's my very deep dive: https://www.quantamagazine.org/physicists-create-a-wormhole-using-a-quantum-computer-20221130/

Love this phrase from the initial caption: "though it’s not clear in what sense the wormhole can be said to exist."
And this related one is a close runner up: "but how to conceptualize this kind of duality remains mysterious."
