Photons and gravitational field

Click For Summary
SUMMARY

The discussion confirms that the B field of a photon can be influenced by the gravitational field of another photon, although the effect is negligible and far below measurable limits. Additionally, it highlights that photons can interact through photon-photon scattering via electron and positron pairs, which presents a significantly stronger interaction. This interaction is crucial for understanding quantum electrodynamics and the behavior of light in gravitational fields.

Can the B field of a photon be affected by the gravitational field of another photon?
 
Science news on Phys.org
Yes, everything is affected by gravity. Allthough in this case, the effect would be exceedingly small, of course. Many orders of magnitude smaller than what is experimentally measurable.

Two photons can also interact via the electron & positron in so-called photon-photon scattering. This would be a much stronger effect.
