When a star wanders too close to a supermassive black hole and is torn apart, the universe does not simply swallow the evidence — it announces itself, sometimes twice. Researchers Adelle Goodwin and Andrew Mummery have identified two distinct windows in which black holes launch powerful jets after consuming stars, with the delayed second phase reliably triggered when feeding rates fall to two percent of the Eddington limit. What makes this discovery resonate beyond the immediate finding is its universality: the same threshold governs jet formation across black holes of vastly different sizes,
