Wobbling jets created by collapsing star may be why gamma ray bursts blink

Watch the evolution of a jet formed by a collapsing star ("collapsar") in these simulations courtesy of Ore Gottlieb/Northwestern University. The wobble of the jets may be the source of mysterious blinking gamma ray bursts (GRBs). -- Gamma-ray bursts might be much rarer than we thought, study suggests: https://www.space.com/gamma-ray-bursts-may-be-rare-study
