- How about the Hawking effect, whereby gravitons could tunnel past
- the black hole's event horizon? (Although I'm sure the graviton
- "flux" due to this effect would not lead to a correct statement as
- to the mass of the object...)
-
- In any event, a prime assertion of General Relativity is that gravity
- is *not a force*, but a characteristic of the geometry of spacetime;
- it seems, then, that the notion of a force propagator (the graviton)
- moving about in spacetime is not consistent with this assertion. And
- as there are no direct experimental data regarding the behavior of
- gravity at the quantum level, can the existence of a neutral, massless,
- spin-2 graviton be justified on symmetry grounds alone?
-
- Any thoughts?
