🧵 Gravitational Prism

Does gravity bend photons of different energies differently? Most sources suggest that the curvature of a massless particle's path is independent of its energy. However, I came across an answer on Physics stackexchange that mentions a non zero scattering angle when considering the gravitational field of the photon itself.

E=MC^2
basically mass and energy are the same and the increase in energy of a particle is an increase in mass, which is that gravitational field you’re talking about. obviously photons have no mass but their momentum is mass like. that said, if the photon has a higher frequency then it has more energy and thus the gravitational field it produces is stronger. obviously to such a minuscule degree

Classically wave fronts of light waves follow null geodesics and this has nothing to do with frequency. I would be surprised if this changes semiclassically (i.e. a quantum EM field but classical curved spacetime), but post the answer on stack exchange.

What is your proof for spacetime curvature.

But it's a kilogram.
