A simple quibble differentiates a black hole from AGN.And now you're having to resort to quibbling.
Do you think that any light in the photon sphere would be less coherent or diffused?
To any useful degree?
More coherent seeing as the most rapidly developing stars form from cluster galaxies surrounding AGN. You see the vortex created by quasars from the photosphere is probably the most orderly mechanism unknown.
Build a really big funnel that studies bosons. Invert the LHC and use it as a telescope.If it's been "collecting light" since sometime AFTER (a point you persist in ignoring) the BB how would you distinguish and separate the information (if it truly is available) that you actually want?
