For instance a hot brick has a little more gravitational pull than a cold brick since its total mass + energy has increased from when it was cold.
Does a moving body have more gravity than a body at rest? My logic is that its kinetic energy would increase, and hence its mass. If so, wouldn't this imply that a photon has mass?
Also, pertaining to Rrhains original question, what happens to the gravity when mass is converted to energy? Does the space-time distortion just get dissipated since the mass/energy is less concentrated?
