1: spooky at a long distance as universal principle.
Democratic Free Will in the Instant Entangled Multiverse.
2: Mass/Gravity related lightspeed "adaptation or extinction" reference frames.
Reconciliation of GR and QM by a New Gravity-Black Hole and Lightspeed Model Called Quantum- FFF Theory.
According to Quantum FF theory, the lightspeed is related to massive objects like planets moons etc.
Babcock and Bergman where not aware in 1964 of the origin of their anomalous experimental lightspeed results, Q-FFF model has the explanation.
Champ satellite anomalies (180 m) used to estimate the minor axis of the LASOF ellipsoid aound the Earth.
IMHO the spacetime acceleration deformation as depicted in the image above, could be more or less a sort of macroscopic Casimir cavity.
As a consequence, Gravitons could be ruled out, not able to leave the black holes.
