As promised... No, classical spacetime can’t produce entanglement. I can create entanglement by turning a knob on a laser, but the knob isn't mediating entanglement. Is the knob "producing" the entanglement? This week's Nature paper is causing confusion! superposer.substack.com/p/no-classic... 🧪⚛️
No they do not. I'll try to write something up in the next few days....

If you're an academic talking to non-academics---or hell, even academics outside your field---you have a responsibility to distinguish between "this is the scholarly consensus" and "this is an active debate which I'm on one side of."

Thanks to Karmela Padavic-Callaghan with @newscientist.com for reporting on my upcoming work with Jonah Kudler-Flam and Gautam Satishchandran (paper to appear soon)!
An eavesdropper hiding inside of a black hole could still obtain information about quantum objects on its outside, a finding that reveals how effectively black holes destroy the quantum states near their event horizons.
Quantum eavesdropping could work even from inside a black hole

If neutrinos are Majorana particles—that is, if they are their own antiparticles—a process called neutrinoless double-beta decay should occur. A new and sensitive search has not found it.
Search Continues for Neutrinoless Decay
Observations of molybdenum nuclei have revealed no signs of a speculative nuclear decay called neutrinoless double-beta decay, setting a strong constraint on this process.

How to Minimize the Decoherence Caused by Black Holes
