@informaq.bsky.socialNew framework reveals some proposed quantum gravity experiments can be explained by classical gravity acting on quantum particles, helping identify signatures that would truly prove gravity's quantum nature.
@informaq.bsky.socialObject-relative mode weighting in a causal resonator suppresses UV divergences in quantum gravity one-loop integrals without counterterms, while naturally predicting dark energy density within order unity of observations.
@informaq.bsky.socialQuantum massive scalar fields exhibit divergent behavior at black hole Cauchy horizons, unlike massless fields. This suggests quantum effects could strengthen interior singularities beyond their classical predictions.
@informaq.bsky.socialPhysicists used ultracold atoms in quantum superposition to directly measure gravity's effect on quantum systems, confirming Einstein's equivalence principle at quantum scales and advancing insights into quantum-gravity unification.
