Power is energy per unit of time." For example, horse power is force (energy) x distance, then divide by unit time. More ENERGY is released than POWER when SBH merge. Most of that energy is released in gravitational waves. Through the release of neutrinos? Most energy of a supernova is released in neutrinos. "In 1966, Colgate and White calculated that neutrinos carry away most of the gravitational energy released by the collapse of massive stars...." https://en.wikipedia.org/wiki/Neutrino#Supernovae Does this also happen with the merger of SBHs?

No, because in the case of a black hole merger there is no matter (*) to produce neutrinos (which are produced by the fusion reactions in a collapsing star) or any other radiation. (*) Unless the black holes have significant accretion disks. I'm not sure what happens in that situation. I'm guessing the answer is: "it's complicated" Edited April 25, 2020 by Strange spelling 1 Link to comment Share on other sites More sharing options...
