We study a nonlocally modified gravity model proposed by Deser and Woodard which gives an explanation for current cosmic acceleration. By deriving and solving the equations governing the evolution of the structure in the Universe, we show that this model predicts a pattern of growth that differs from standard general relativity (+dark energy) at the 10-30% level. These differences will be easily probed by the next generation of galaxy surveys, so the model should be tested shortly.

  1. Nonlocal gravity in a proper tetrad frame: traversable wormholes

    gr-qc 2025-01 conditional novelty 6.0 of 10

    Static, spherically symmetric traversable wormholes are built in revised Deser-Woodard nonlocal gravity by reconstructing the theory's distortion function from chosen wormhole metrics.
