Across the observable universe, certain stars have been caught in a slow gravitational waltz with supermassive black holes — returning again and again, each time a little dimmer than before. For years, this fading defied explanation, as existing models predicted the brightness should hold steady. Now, a team from Syracuse University has traced the mystery to something as intimate as a star's own spin, revealing how the deep past of a stellar pair can quietly shape the light we see millions of years later.
