Gamma-ray bursts (GRBs) are among the most powerful events in the universe, believed to stem from massive star collapses or neutron star mergers. Detected first as intense flashes of gamma rays, these bursts can release more energy in a few seconds than our Sun will emit in its entire lifetime. The mystery lies in understanding the exact processes driving these eruptions, which are still subjects of extensive research.
FAQs & Answers
