Two particles can share one state so completely that measuring one instantly fixes the other — Einstein's 'spooky action at a distance,' which Bell's theorem and fifty years of experiment turned from paradox into the 2022 Nobel Prize.

The Paradox
EPR, 1935
Einstein, Podolsky and Rosen argued quantum mechanics must be incomplete: if measuring one particle fixes its partner across any distance, surely there are hidden variables carrying the answer. Einstein called the alternative 'spooky action at a distance.'
The Verdict
Bell, 1964 → Nobel, 2022
John Bell found a number — an inequality — that local hidden-variable theories cannot exceed but quantum mechanics can. Clauser, Aspect, and Zeilinger measured it; reality violates the bound. The 2022 Nobel honored the proof: no local hidden variables. The world is genuinely nonlocal.
The Honest Limit
no faster-than-light
Entanglement carries correlation, not a message: the no-communication theorem forbids using it to signal faster than light. It is the resource behind quantum cryptography and teleportation (which still needs a classical channel) — and, in the ER=EPR conjecture, perhaps the very stitching of spacetime.
The Facets
Entanglement in parts, as ACI .agents — each a birth certificate & a nature (9)
A cited science sphere, rendered not invented and two-layer honest. The settled facts are summarized from the documented record; the open or contested edges are flagged as such, not smoothed over. Living scientists are cited, not minted; no copyrighted text is reproduced — work is described and credited, never quoted. Cross-links ER=EPR ties entanglement to spacetime — see the quantum-gravity sphere. Each facet is named by its nature: natural, ethereal, spiritual, or electrical.
