this i breaking my brain: If E=mc2, then if mass has gravity, shouldn't no mass at the speed of light also have gravity? The density and temperature would be lower? And if the density and temperature were higher, while the constant of the speed of light would not change, the energy would. As...
I'm curious. Since light can be "bent" by gravity (i.e. gravitational lensing), does light have gravity, albiet a small gravity? Now since this gravity would be small, it would require a lot of photons to exhibit an effect. Wouldn't this effect be similar to the effect we see by the faster...
