A quasar is an astronomical source of electromagnetic energy, including light, which shows a very high redshift.
The scientific consensus is that this high redshift is the result of Hubble's law. This implies that quasars are very distant.To be observable at that distance, the energy output of quasars must
dwarf that of almost every known astrophysical phenomenon with the
exception of comparatively short-lived supernovae and gamma-ray bursts. more...
