Query: Effect of gravitational field self-interaction on large structure
  formation   We check whether General Relativity's field self-interaction alleviates the
need for dark matter to explain the universe's large structure formation. We
found that self-interaction accelerates sufficiently the growth of structures
so that they can reach their presently observed density. No free parameters,
dark components or modifications of the known laws of nature were required.
This result adds to the other natural explanations provided by the same
approach to the, $inter~alia$, flat rotation curves of galaxies, supernovae
observations suggestive of dark energy, and dynamics of galaxy clusters,
thereby reinforcing its credibility as an alternative to the dark universe
model.
