Evidence (3.4σ) from @atlasexperiment.bsky.social that Higgs bosons decay into muon pairs, as predicted by the Standard Model mass mechanism for leptons as laid out in Steven Weinberg's 1967 model of leptons. Glibly, Weinberg was right.

Realization of the Einstein-Bohr Gedankenexperiment using a single atom as tunable recoiling "slit" 🧪⚛️ #IYQ2025
PRL: go.aps.org/44C02Fn
PhysMag: go.aps.org/4pf6bQl
Fig. 1: The concept of the Einstein-Bohr Gedankenexperiment and its realization. (a) Schematic of single-photon interference with a movable slit. A photon scatters off the slit, entangling its path with the slit’s momentum. (b) Our experimental realization using a single atom trapped in an optical tweezer and prepared in quantum ground state, which serves as the movable quantum slit.

** STEPHEN HAWKING WAS RIGHT **

Using a very strong black-hole merger signal, the @LIGO-@ego_virgo-@KAGRA_PR Collaboration has shown the 2nd law of black hole mechanics, Hawking's area law (A_final > A_initial), to hold with high credibility.
