Supermassive stars with masses of ~55,000 M_Sun, however, have been found to explode and completely disrupt in a supernova (SN) with an energy of up to ~10^55 erg instead of collapsing to a BH. Such events, ~10,000 times more energetic than typical SNe today, would be among the biggest explosions in the history of the universe. Here we present a simulation of such a SN in two stag","authors_text":"Alex Heger (Monash), Chris L. Fryer (LANL), Daniel J. Whalen (LANL, Heidelberg ITA), Jarrett L.
