Why graviton particle theory concept is not accepted?

Click For Summary

Discussion Overview

The discussion revolves around the concept of the graviton particle theory and its acceptance within the scientific community. Participants explore the existence of gravitons, the lack of experimental evidence, and the theoretical implications of incorporating gravitons into existing frameworks such as Quantum Field Theories and the Standard Model of particle physics.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory

Main Points Raised

  • Some participants question the existence of gravitons, noting that there is currently no experimental support for them.
  • Others argue that General Relativity, which does not include gravitons, remains a successful theory in explaining gravitational phenomena.
  • A participant suggests that the lack of direct evidence for gravitational waves raises further questions about the acceptance of graviton theory.
  • It is proposed that Quantum Field Theories have been effective in describing the other three fundamental interactions, leading to hopes that a similar approach could be applied to gravitation, thus supporting the idea of gravitons.
  • Concerns are raised about the challenges of integrating gravitons into the Standard Model of particle physics, indicating ongoing theoretical and mathematical difficulties.

Areas of Agreement / Disagreement

Participants express differing views on the existence and acceptance of graviton theory, with no consensus reached on the matter.

Contextual Notes

The discussion highlights limitations in current experimental evidence and the complexities involved in reconciling graviton theory with established physics frameworks.

Not currently known, there is no experimental support for the graviton at this time. On the other hand, General Relativity (which does not postulate gravitons) is a successful theory.
 
A better question would be why would a graviton particle theory be accepted. There is no direct evidence for gravitational waves, much less gravitons, so why would their existence be accepted?
 
Well, since Quantum Field Theories were really effiecient in describing the other 3 interactions, people hope it can be used for gravitation as well, that's why graviton is hoped to exist.

Postulating the existence of such a particle will also give Newton's 1/r law in the classical limit(just like GR), which is a good thing, but... There are problems with incorporating gravitons to the Standard Model of praticle physics, so this is kind of one frontier of theoretical(and mathematical) physics...
