Not Black Holes: Astronomers May Need To Rethink How Gamma … – SciTechDaily

According to recent research from the University of Bath in the UK, newborn supramassive stars, rather than black holes, may be the cause of gamma-ray bursts.
Satellites orbiting Earth have detected Gamma-ray bursts (GRBs) as luminous flashes of extremely energetic gamma-ray radiation that last from milliseconds to hundreds of seconds. These catastrophic blasts occur in distant galaxies billions of light-years away from Earth.
A type of GRB called a short-duration GRB is produced when two neutron stars collide. These ultra-dense stars, which have the mass of our Sun compressed into a size smaller than a city, generate ripples in space-time called gravitational waves
