Johnny may have got the Mercury transit & light bending tests mixed up: The light bending was the 'great exciting newspaper front page' (Testing Einstein's Universe, Stanford University)Can't find support for Johnny's 'light travels on a crisp' theory, but here's some smart people debating 'What stops photons from traveling faster than the speed of light' (Quora)Cheeky review? (If we may be so bold)
