Why graviton particle theory concept is not accepted?

In summary, the existence of gravitons, particles that carry the force of gravity, is still uncertain and not supported by experimental evidence. While some hope that Quantum Field Theories can also explain gravity and thus the existence of gravitons, there are challenges in incorporating them into the Standard Model of particle physics. This remains an important area of study in theoretical physics.

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...
 

1. Why is graviton particle theory not widely accepted by scientists?

The main reason why graviton particle theory is not widely accepted by scientists is because it is still a theoretical concept and has not been proven through experimentation or observation. While the theory is mathematically sound, there is currently no experimental evidence to support its existence. Additionally, the concept of a graviton particle conflicts with other well-established theories, such as general relativity.

2. What are some challenges with the graviton particle theory?

One of the main challenges with the graviton particle theory is that it is difficult to reconcile with quantum mechanics. The theory suggests that gravity is transmitted through a particle, but this conflicts with the principles of quantum mechanics which state that particles cannot have both a definite position and momentum at the same time. Additionally, there is currently no way to detect or measure gravitons, making it difficult to test the theory.

3. Are there any alternative theories to the graviton particle theory?

Yes, there are several alternative theories to the graviton particle theory that attempt to explain the force of gravity. One example is loop quantum gravity, which proposes that gravity is a result of interactions between space-time itself. Other theories, such as string theory, also attempt to incorporate gravity into a larger framework of fundamental forces.

4. What is the current status of research on graviton particles?

The research on graviton particles is ongoing and is a subject of interest for many scientists. While there is currently no experimental evidence for their existence, researchers are working on ways to detect and measure gravitons. Additionally, advancements in technology and new theories may shed more light on the concept in the future.

5. Could the graviton particle theory ever be proven or accepted in the future?

It is possible that the graviton particle theory could be proven or accepted in the future. As technology and scientific understanding continue to advance, there may be new ways to test and support the theory. However, until there is concrete evidence, it is unlikely that graviton particles will be widely accepted by the scientific community.
