Some introductory line about me apologizing for my ignorance and inability to find answers on interwebs.
If photons get affected by gravitational field (or follow the curvature of space-time created by nearby massive objects) and have in essence some non-rest mass how come they don't just fall down due gravity? Shouldn't all things fall at same rate regardless of their mass, no matter how small?
I understand that photons are just too fast so it's not really observable, but what about when traveling much slower through a specific medium? What about when reflected back and forth or in circle for longer time period? Shouldn't it start to fall? It is still going through curved space-time and being affected by gravitational field, right?
Thanks in advance.
