If photons have no mass, why are they affected by gravity? (Strange Universe series)
Photons behave partially like particles and partially like waves, but unlike things we think of as particles, photons have no mass. Most of us are familiar now with the lensing effect of large gravity fields. How does the gravity well of a very large mass affect a photon if the photon has no mass?
