@tarpeyd12 A massless particle has, by definition, no mass, or if you prefer a mass = 0. According to the 2nd law of Newton, F = m . a. Since F is the gravity force we're interested in, F = G . m1 . m2 / d² = m1 . a. So, a = G.m2 / d². This means that acceleration a particle is subject to, is not dependent on this particle's mass. Si this means that a massless particle does not modify the gravity field, it does not change acceleration on any other particle.

@tarpeyd12 Massless particles get accelerations only from massfull particles. And massfull particles get accelerations only from massfull particles.
