Dark matter, dark energy, and a possible modelling error.
This page gives a short English orientation to a German-language public-facing volume. The book translates the dark-sector argument of Two Symptoms, One Failure into a broader cosmology narrative.
The book does not deny the observations behind dark matter and dark energy. It asks whether the standard interpretation of those observations is fully licensed in the relevant regimes, and whether Backreaction and model assumptions should be made more explicit in cosmological reasoning.
