SUMMARY

The discussion centers on the relationship between acceleration and light emission by charged particles, specifically electrons, in different gravitational contexts. It establishes that while an electron on Earth experiences acceleration due to gravity, it does not emit light, contrasting General Relativity (GR) and Newtonian Mechanics (NM). The key conclusion is that in GR, an object in free fall is not considered to be accelerating, which explains the lack of radiation from stationary charges on Earth. The inquiry highlights the complexities of energy sources for light emission in these frameworks.

PREREQUISITES
  • Understanding of General Relativity (GR) principles
  • Familiarity with Newtonian Mechanics (NM)
  • Knowledge of electromagnetic radiation and charge behavior
  • Basic concepts of acceleration and reference frames
NEXT STEPS
  • Research the implications of General Relativity on electromagnetic radiation
  • Explore the differences between GR and NM regarding acceleration
  • Study the conditions under which charged particles emit radiation
  • Examine the concept of free fall in various gravitational fields
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the interplay between gravity, acceleration, and electromagnetic radiation.

If standing on Earth and being accelerated by a rocket out in space at g are the same thing, Or at least have the same effects. And if accelerating charges emit light then would an electron sitting on Earth emit light? But I don't see how this is possible because where would the energy come from.

There has been another thread on this recently. This is not an easy question to answer. In General Relativity an object in free fall is not accelerating but in Newtonian mechanics it is. Conversely an object sitting on the surface of the Earth is accelerating in GR but not in NM. The charge sitting on the Earth is not seen to radiate, why?
