I read about the concept of the above, but is their any proof that a) they exist and/or b)they are the cause of gravity?
Gravitons are hypothetical particles that are thought to be responsible for mediating the force of gravity between objects in the universe. They are predicted by certain theories, such as string theory, but have not yet been directly observed.
The existence of gravitons is still a topic of debate among scientists. While some theories, such as string theory, predict their existence, there is currently no direct evidence to support this. Some scientists believe that a better understanding of quantum gravity may one day confirm the existence of gravitons.
Gravitons are believed to be responsible for the force of gravity between objects. According to the theory of general relativity, gravity is the result of the curvature of spacetime caused by the presence of mass and energy. Gravitons are thought to transmit this force between objects by interacting with their mass and energy.
As of now, there is no way to directly detect gravitons. This is because they are predicted to have very low energy and interact extremely weakly with matter. Scientists are currently working on developing new technologies and experiments that may one day be able to detect them indirectly.
If gravitons were to be discovered and their existence confirmed, it would have significant implications for our understanding of the universe. It would provide evidence for the unification of quantum mechanics and general relativity, which has been a major goal in physics for decades. It could also help scientists better understand the fundamental forces of nature and the structure of the universe at a microscopic level.
