Discussion Overview

The discussion centers on whether the electromagnetic, strong, and weak forces can be expressed in geometric terms, similar to gravity. Participants explore various theories and historical attempts to unify these forces geometrically.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • Some participants note that gravity is expressed geometrically and question if this is unique to gravity or if other forces can also be expressed in a similar manner.
  • One participant mentions Heim Theory as a potential framework for geometric expression of forces.
  • Another participant references historical efforts, including Einstein's hope to explain all forces geometrically, and discusses the shift towards quantum explanations for gravity, particularly through String Theory and the search for gravitons.
  • A participant introduces Geometrodynamics, developed by John Wheeler, which was an attempt to express gravity geometrically but was abandoned due to its limitations.
  • Gauge theories are mentioned as a geometric approach, suggesting that some frameworks may already incorporate geometric principles for forces.

Areas of Agreement / Disagreement

Participants express a range of views on the possibility of geometrically expressing forces other than gravity, with some proposing specific theories while others reference historical attempts that have not succeeded. The discussion remains unresolved regarding the feasibility of such geometric formulations for all forces.

Contextual Notes

Participants reference various theories and historical approaches without reaching a consensus on their effectiveness or applicability to the forces in question. The discussion highlights the complexity and ongoing exploration in the field.

gravity is expressed geometrically. is this expression unique to gravity or are there formallism that allow charge/EM, color/strong force, and weak force to also be expressed geometrically?

Heim Theory.
 
That's actually what physicists used to look for. It was the hope of Einstein to explain all the forces in geometrical terms. But since they have had more luck combining the other three forces, physicists are trying to express gravity in quantum terms. And it was done with String Theory. The theory actually requires the existence of a particle called a graviton. One goal of modern physics is to locate these gravitons and find out where they come from.

You might want to take a look at (my) posts #6 and #8 in https://www.physicsforums.com/showthread.php?p=684671".
