Newton thought gravity was a force, but relativity says otherwise. What we call "gravity" is, in fact, a "downward" (note that there's no "up" or "down" in space; this is just to make the explanation easier to understand) distortion of spacetime by particles with mass. In other words, particles (regardless of mass) are simply following the curvature of spacetime created by particles with mass. Even light must follow that curvature, since all things exist within spacetime and can only go where there is spacetime (the Universe).

If you'd like to discuss this further, leave me a message when you can chat.
