Classical time crystal via nonreciprocal forces (breaks Newton's third law).
A classical time crystal made from two beads and a loudspeaker broke a symmetry that had held in physics for three centuries, and the mechanism was nonreciprocal coupling: forces that do not balance. The programme's interest is specific. Paper III had framed nonreciprocal feedback as the physical instance of the recursive amplification pattern, mapped the asymmetry term onto its own equation, and stated a falsification condition for the mapping. The NYU result is independent physics by independent physicists; the register claims convergence of structure, not influence.

Open the primary source above. Confirm the date. Confirm the finding. Then compare it against the manuscript passage or artifact named in the register entry, whose SHA-256 hash is published on the evidence page. Nothing in this article asks for trust; the entry either survives that comparison or it comes off the register, publicly, the way the programme's retracted scaling figure did.
