Discussion Overview

The discussion revolves around the interaction of gravity with various wave forms, including electromagnetic waves such as gamma, x-ray, and radio waves. Participants explore the nature of gravity, questioning whether it can be classified as a wave and how it influences other wave forms, particularly in the context of General Relativity.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • Pat Hagar questions how gravity affects different wave forms and whether gravity itself can be considered a wave.
  • Some participants assert that gravity does affect electromagnetic waves, while others argue that gravity is not a wave.
  • There is mention of the recent confirmation of gravitational waves, but participants clarify that this does not imply gravity itself is a wave.
  • One participant references the historical context of General Relativity and its prediction of light bending due to gravity, emphasizing the impact of mass on the curvature of space and time.

Areas of Agreement / Disagreement

Participants express differing views on whether gravity can be classified as a wave, with some agreeing that gravity affects electromagnetic waves while others contest the notion of gravity being a wave itself. The discussion remains unresolved regarding the classification of gravity.

Contextual Notes

Participants have not fully explored the implications of their definitions of waves or the nuances of gravitational interactions with different wave forms. There are also unresolved aspects regarding the relationship between gravitational waves and the nature of gravity itself.

Does gravity affect waves such as gamma, xray, radio etc. and how does it interact with other wave forms considering gravity is a wave itself.

Yes, gravity affects EM waves.

No, gravity is not a wave.

I have read in the last few months that gravitational waves have finally been proven to exist.

Yes, this does not mean that gravity is a wave. Just as EM waves do not mean an electric field is a wave or waves on the surface of a pond mean that the surface is a wave.
 
Thank you for the response. That sounds reasonable.

Not only "yes", but very famously "yes". With General Relativity Einstein predicted twice as much light bending as Newtonian gravity. The race was on to try and measure the bending precisely by observing stars near the edge of the solar disk during a solar eclipse. When Einstein's value was confirmed in 1919 it made headline news around the world and made Einstein world famous. I saw a really good documentary about the race and frustrations of trying to make the solar eclipse measurement.

Anyhow, I will add that the idea of General Relativity is that mass bends space and time. Everything must be affected when space itself is bent!
 
Thank you for the in depth explanation. This makes things much clearer.

Respectfully,
Pat Hagar
