According to Hawking [1] it is posited that light photons at the event horizon of a black hole must cease to move, and remain motionless for the entire lifetime of the black hole.
It is also observed [http://dls.physics.ucdavis.edu/~scranton/LensedCMB/a2218.gif] (and calculated) that the path of light will be bent by a sufficiently massive object, due to the curvature of spacetime around that object.
Now, since gravity is a long-range force, I was wondering if it is possible for conditions to exists under which a photon could orbit an object due their gravitational attraction? If so: what would these conditions be; how can we observe it; and what implications, if any, does this have?
