The equivalence principle in GR states inertial mass and gravity are equivalent, what about massless particles?
Is there inertial mass-gravity equivalece principle with photons?

SUMMARY
The discussion centers on the equivalence principle in General Relativity (GR), which asserts that inertial mass and gravitational mass are equivalent. It raises the question of how this principle applies to massless particles, such as photons. The reference to the paper available at arXiv (http://arxiv.org/abs/gr-qc/9909014) indicates ongoing research into the implications of this principle for massless entities. The conclusion drawn is that while the equivalence principle holds for massive particles, its application to massless particles requires further exploration.
PREREQUISITES- Understanding of General Relativity (GR)
- Familiarity with the concept of mass and inertia
- Knowledge of photon behavior in physics
- Basic grasp of theoretical physics research methodologies
- Read the paper "On the Equivalence Principle and Massless Particles" on arXiv
- Explore the implications of the equivalence principle in GR for massless particles
- Investigate the role of photons in gravitational fields
- Study the differences between inertial mass and gravitational mass in detail
This discussion is beneficial for theoretical physicists, researchers in gravitational physics, and students studying General Relativity who seek to understand the nuances of mass and gravity in relation to massless particles.
