Gravity causes homogeneity of the universe

'During its expansion, the universe evolved towards its present state, which is homogeneous and isotropic on large scales. This is inferred, among other things, from the measurement of the so-called background radiation as nicely seen in the full sky image of the WMAP data. New results published in the renowned journal PRL show that homogenization in the investigated class of cosmological models is already completely explained by Einstein's theory of gravity and does not require any additional modifications.'

(© NASA / WMAP Science Team) Gravity can accelerate the homogenization of space-time as the universe evolves. This insight is based on theoretical studies of the physicist David Fajman of the University of Vienna. The mathematical methods developed within the research project allow to investigate fundamental open questions of cosmology such as why the universe today appears so homogeneous.
