Not sure why the headline makes it sound goofy (Halloween on their mind?) and the press release isn't very helpful.

But this is apparently a publishable result for realizing entanglement in an atomic physics experiment.

It has nothing to do with Halloween. It's referring to "spooky action at a distance" which is what Einstein called entanglement when it was discovered. He didn't understand it so he called it "spooky" because one particle could mysteriously control another particle far away.

I get the Einstein reference, but it still seems heavy-handed in the headline.

listen there's only a few physics jokes that are accessible to everyone to begin with lmao

Yes it’s spooky action theory

This is spooky as fuck.
