Question:
If gravitons can be described as both wave and particle by wave-particle duality, then can "gravitons" be described as quantum-wave functions? Not ripples in space-time curvature that travel at speed "c", but wave functions that have an associated non-locality aspect?

Replies:
While outside of my sphere of expertise, my readings on the subject of gravity suggests to me that the answer is: No one knows, because there is no quantum theory of gravity. That nothing can travel faster than "c" -- there seems to be broad agreement on that -- the details of what the wave function of a gravitational field might look like is much less clear. Wish I could be more help.
