Математически показано, что однородность Вселенной может быть объяснена гравитационными волнами на начальной стадии расширения, и теория инфляции, противоречащая теории относительности,  не нужна. Таким образом, общая теория относительности Эйнштейна восторжествовала в эволюции Вселенной.

[QUOTE]Such analyses are based on modern mathematical methods in the field of geometric analysis. Until now, these methods could only achieve such results for small deviations from the homogeneous space-time geometry. David Fajman from the University of Vienna has now succeeded for the first time to transfer these methods to the case of arbitrarily large deviations.

The results published in the renowned journal PRL show that homogenization in the investigated class of models is already completely explained by Einstein's theory and does not require any additional modifications. If this finding can be transferred to more general models, it means that it does not necessarily need a mechanism like inflation to explain the state of our present universe, but that Einstein's theory could finally triumph once again.[/QUOTE]
