Hello, We know that light get bent near stars (because of its gravitational force), and in fact it cannot escape the gravitational forces of black holes. We also know from Newton's laws of gravity that the gravitational attraction between any two objects is ZERO if any mass is ZERO. We also know that photons (light) have ZERO mass. So, if light has no mass, then why is it affected by any gravitational force ????? Am I missing something ? Thanks.
