The electric and magnetic fields of electromagnetic radiation remain perpendicular even in the presence of an intense gravity field, as confirmed by local observers measuring these fields. In curved spacetime, the local behavior of light mirrors that of flat spacetime, maintaining the speed of light at ##c##. However, significant spacetime curvature at a quantum mechanical scale necessitates modeling light as a quantum field phenomenon rather than as classical electromagnetic waves.
PREREQUISITESPhysicists, astrophysicists, and students of theoretical physics interested in the interaction between electromagnetic radiation and gravitational fields.
The local behaviour of light in curved spacetime is the same as in flat spacetime (no gravity). A local observer measuring the local EM fields would get the same results as expected classically.tmhen said:Summary:: Electric and magnetic fields of electromagnetic radiation in intense gravity.
Does the electric and magnetic fields of electromagnetic radiation remain perpendicular in the presence of an intense gravity field? If not, what is the physical ramifications of this?
