In summary, the conversation discusses the concept of spin state in particles and the role of measurement in determining it. The question of whether the gravitational field can act as an "observer" in quantum mechanics is also raised. The conversation also mentions John Bell's experiments, which were not actually performed by Bell himself.

As John Bell showed us a particle is not in a spin state until we measure it. So would a Graviton always be in a definite spin state because it would always be interacting with the gravitational field.

Your just pointing to the usual problem of measurement of QM, is the gravitational field an "observer" in the sense of the Copenhagen interpretation of QM?

Baloney. Since your premise is nonsense, there is no need to go further.

If there's something you don't understand, it's better to ask than to state something wrong.

ok then what is the purpose of Bell's experiments.

1. Bell didn't perform any experiments.
2. You're hijacking your own thread.
 

1. What are gravitons?

Gravitons are theoretical particles that are thought to be responsible for mediating the force of gravity in the universe. They are predicted by the theory of quantum mechanics and are believed to be the carriers of gravitational energy.

2. How do gravitons work?

Gravitons are believed to work by interacting with other particles, such as protons and neutrons, to transmit the force of gravity between them. It is theorized that gravitons are constantly being exchanged between all particles with mass, creating the gravitational pull we experience.

3. Are gravitons proven to exist?

As of now, gravitons have not been directly observed or proven to exist. However, scientists continue to search for evidence of these particles through experiments and observations in order to further understand the nature of gravity and the universe.

4. Can gravitons be detected?

Currently, there is no technology available to directly detect gravitons. This is because they are incredibly small and have extremely low energy levels, making them difficult to observe. Scientists are working on developing new technologies and experiments to potentially detect gravitons in the future.

5. What is the significance of gravitons?

Gravitons are important in understanding the fundamental forces of the universe and the nature of gravity. If they are proven to exist, it would provide evidence for the theory of quantum gravity and could potentially lead to a unified theory that explains all the forces of nature. Additionally, the discovery of gravitons could have practical applications in fields such as space travel and communication.
