General Relativity vs Geometrodynamics

Click For Summary

Discussion Overview

The discussion centers on the differences and similarities between Einstein's General Relativity and Wheeler's Geometrodynamics, exploring whether they represent the same theoretical framework or distinct concepts. The scope includes theoretical implications and interpretations of these frameworks.

Discussion Character

  • Debate/contested

Main Points Raised

  • Some participants propose that General Relativity and Geometrodynamics are essentially the same, with Geometrodynamics being a term coined by Wheeler to highlight the dynamic nature of space-time geometry.
  • Others argue that Geometrodynamics is not merely a renaming of General Relativity, suggesting it aims to extend the geometrical approach to encompass all classical fields and potentially quantum fields, as well as to provide a geometrical description of physical quantities like charge.

Areas of Agreement / Disagreement

Participants express differing views on whether General Relativity and Geometrodynamics are the same or distinct concepts, indicating that the discussion remains unresolved.

What are the difference between Einstein's General Relativity and Wheeler's Geometrodynamics,or they are the same thing?

They are the same thing, IMHO. I think Wheeler just coined the term Geometrodynamics to emphasize that in General Relativity the geometry of space-time is a dynamic entity.
 
Thanks.
 
I might be wrong, but I think geometrodynamics is not just a different name for general relativity. It was supposed to push the idea to the limit and geometrize all classical fields, may be even quantum, and give geometrical description of physical quantities such as charge. Hence the "charge without charge" and so on motto.
