Hi. You seem to understand cosmology.
Here's a childish question...
at what angle should one look at the BH to see the light of our sun? well, this is provided that the light can actually bend in the vicinity of the BH and change its trajectory.
then the light from our sun should really be visible through a telescope.
Maybe that would reveal something new... and if not, that's fine
just there the distance is only 51 600 light years) and maybe our earth will be visible) sounds pretty damn fantastic but at the same time ingenious logically))))
