Does time-like curvature of spacetime cause light to bend, for example, around the sun? Or is the gravitational bending of light only due to the space-like curvature? So far, I understand the concepts as: Time-like curvature is caused by the mc^2 part of E, while space-like curvature is caused by the pc part of E. So the sun should have a huge curvature time-wise, but very little space-wise (perhaps only due to its rotation?). Since photons have zero rest mass, they only have the space-like component of their energy (just the pc part), and so should only be bent by space-like curvature. So a perfectly still mass should not bend light? I think I'm wrong here somewhere. Do photons still have a time-like component to their energy despite having zero rest mass? Need some help here...confused...
