Question

If gravitons exist, are they always detectible in any frame? I'm asking because if I'm in a freely falling frame in a uniform gravitational field, and I detect gravitons, I will no longer be able to say that my frame is equivalent to another inertial frame in which there are no gravitons. Is this line of reasoning accurate?

Answer 1

Gravitons are hypothetical particles that mediate the force of gravity, but have not been detected experimentally. The presence or detection of gravitons does not affect the equivalence of different reference frames.

Step-by-step explanation:

Gravitons are hypothetical particles that are believed to mediate the force of gravity in theories of quantum gravity. However, gravitons have not been detected experimentally yet, so their existence is still a subject of investigation in theoretical physics.

In terms of your line of reasoning, it is important to note that the presence or detection of gravitons does not necessarily affect the equivalence of different reference frames.

The principle of equivalence in general relativity states that an observer in a freely falling frame experiences the same physics as an observer in an inertial frame, regardless of the presence of gravitons.

In other words, the detection of gravitons in a freely falling frame would not invalidate the equivalence to an inertial frame without gravitons, as long as the frames are free from non-gravitational forces.
