I have read this question:
I have read this on wikipedia:
However, if gravitons are the quanta of gravitational waves, then the relation between wavelength and corresponding particle energy is fundamentally different for gravitons than for photons, since the Compton wavelength of the graviton is not equal to the gravitational-wave wavelength. Instead, the lower-bound graviton Compton wavelength is about 9×109 times greater than the gravitational wavelength for the GW170104 event, which was ~ 1,700 km. The report did not elaborate on the source of this ratio. It is possible that gravitons are not the quanta of gravitational waves, or that the two phenomena are related in a different way.
So are gravitational waves made up of gravitons or are they just waves in the fabric of spacetime?
It is a contradiction, because spacetime itself should not be made of anything that we know as of today, we do not know what spacetime is made of, we do not even know if there is a fabric of spacetime or what it is.
Gravitational waves are disturbances in the curvature (fabric) of spacetime
So GWs are disturbances in the fabric of spacetime, and gravitons are the quanta of GWs. This would mean that spacetime is made of gravitons, which has to be a contradiction.
are GWs made up of gravitons, or not?
are gravitons the quanta of GWs or not?
