17:4717:47, 19 November 2024 diff hist +8 m Quasar more precise language Tag: Reverted
17:4317:43, 19 November 2024 diff hist +31 Quasar i hope this new rewording is satisfactory, but an object may have a much larger LUMINOSITY than a galaxy (visible output) and yet emit less ENERGY than a galaxy (general output). Tag: Reverted
17:4117:41, 19 November 2024 diff hist 0 Quasar the emissions are not powered by the black hole, because the black hole doesn't lose a single bit of energy Tag: Reverted

18:3818:38, 18 November 2024 diff hist −15 Quasar Undid revision 1258202710 by Parejkoj (talk) no it isn't. there is a difference between luminocity and emitted energy. i can give you an object that has zero luminocity but emits lots of energy (namely in the INVISIBLE part of the spectrum, to which the human eye is not sensitive) Tags: Undo Reverted

21:3621:36, 17 November 2024 diff hist −15 Quasar 1) the black hole itself doesn't lose energy in the emission process 2) luminocity does not measure energy Tag: Reverted
