    BICEP2 all over again. 2014: primordial gravitational waves, Nobel whispers, then dust. Microwaved dust. Years of headlines for a footnote. Now one star’s orbit supposedly hands us the spin of Sagittarius A*. Same breathless maybe, shinier telescope, and the same odds of a retraction six months later. Wake me when it isn’t dust.
