General Relativity vs Geometrodynamics

Click For Summary
SUMMARY

Einstein's General Relativity and Wheeler's Geometrodynamics are fundamentally interconnected, with Geometrodynamics serving as an extension of General Relativity. Geometrodynamics emphasizes the dynamic nature of space-time geometry, aiming to geometrize all classical fields and potentially quantum phenomena. This approach seeks to provide a geometrical description of physical quantities, encapsulated in the concept of "charge without charge." The discussion highlights the philosophical and theoretical implications of these frameworks in understanding the universe.

PREREQUISITES
  • Understanding of Einstein's General Relativity

NEXT STEPS
  • Research the mathematical foundations of General Relativity
  • Explore the implications of Geometrodynamics on classical fields
  • Investigate the concept of "charge without charge" in theoretical physics
  • Study the potential unification of classical and quantum theories through geometry
USEFUL FOR

Theoretical physicists, cosmologists, and students of advanced physics interested in the relationship between General Relativity and Geometrodynamics.

What are the difference between Einstein's General Relativity and Wheeler's Geometrodynamics,or they are the same thing?
 
Physics news on Phys.org
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.
