Most graviton pressure comes from the anti symmetric Vacuum pressure,(3) therefor, it shows mainly infinite speed results. from the vacuum (see: Tom van Flandern) However,the LIGO merger gravity waves speeds tell that there is the speed of light.!!
THE ORIGIN of LIGO, should be that variations ( the waves of Plansk length variations) in the oscillating vacuum are just like gravitons relayed with the local speed of light in the Galaxy.. It seems local by the vacuum influence of the multiple large GABHs ( dual or triple Galaxy Anchor Black Holes) .
Conclusion Quantum Gravity is based on TWO quanta, the graviton and the oscillating Vaccuum (Axion-Higgs) quantum see: respectivily: ( 6 and 3)
Only a tiny part gravitons, in contrast all other photons seems responsible for the rest gravity, these photons leaving the earth, are created by the vacuum Axion transformation by collision with Fermions in the earth. (Q_FFF Theory).
Wikipedia says on gravitational merger waves:
"Gravitational waves are disturbances in the curvature of spacetime, generated by accelerated masses,
that propagate as waves outward from their source at the speed of light. "

Black Holes do not emit gravitons , consequently only the vacuum pressure of the dark energy /Axion-Higgs vacuum photons is involved.
