    It sounds like you're asking if light would orbit something with a lot of mass and gravity. Yes, Light can under the right conditions such as a black hole is perfect but this can only work depending on distance and angle you shine you light, Neil deGrasse Tyson explains this in one of the episodes of Nova Science Now and I cant find the episode so if anyone finds it could you please send me the link.

    But in a nutshell, orbital velocity decreases as you move away from a central mass. It's not going to *increase* up to the speed of light.

    What I thought is that at some point, in empty space, the gravitational field of earth be it so slight would slightly curve light very slightly, but some, if it was curved it would eventually orbit. I think I see where I made my logical error though.
