A Quantum Diaries Survivor has a guest post offering up a theoretical justification for a Higgs boson mass exactly equal to one half of the sum of the masses of the three weak force bosons.
Proponent Ashay Dharwadker argues that he and a colleague have developed a true Grand Unified Theory, maybe even a Theory of Everything, that approximates the Standard Model and general relativity with almost no beyond the Standard Model physics. It isn't the first time I've seen the proposal discussed, although arguably it is the most respectable. This should be incredibly exciting and even transformative, and the fact that it doesn't seem to be suggests room for some healthy skepticism. But, it is worth a look one of these days.
