I can't figure out why it should. Here's what I'm thinking:
- Light is affected by the gravity, and gravity is the interaction between masses, so surely light must have mass in some form.
- Light has no mass, but has energy depending on the frequency of the photon. By E = mc^2, photons with higher frequency should have more mass, and therefore should surely move slower. I have heard of observations though from far out in space (can't remember any specifics, sorry) where two photons from the same event but of different frequencies will be detected at the same time, surely indicating that the energy of the photons does not affect the velocity.
- If light has mass, then surely it cannot travel at the true speed of light.
Can someone explain please?
Thank you
