Research from an international team of scientists led by the University of Leicester has discovered for the first time that one of the most powerful events in our Universe, Gamma-Ray Bursts (GRB), behave differently than previously thought. The study, published in the prestigious scientific journal Nature, uses evidence from observation of a GRB to rule out most of the existing theoretical predictions concerning the afterglow of the explosions.
