Seven-Hour GRB Hints at a Wandering IMBH Feeding on a Star

GRB 250702B is the longest gamma-ray burst on record, lasting seven hours with three separate bursts in a day. Researchers propose it may have been produced when a Sun-like star was tidally disrupted by an intermediate-mass black hole, creating a relativistic jet; the star could have been shredded in multiple passes, and the event's location away from the galaxy's core supports the IMBH scenario, though competing models remain and evidence is contested.
