Bianchi I Spacetimes in f(Q)‐Gravity

Fortschritte der Physik, Volume 74, Issue 8, August 2026.
ABSTRACT The Kasner spacetimes are exact solutions that are self‐similar and of significant interest because they can describe the dynamic evolution of kinematic variables near the singularity of the Mixmaster universe. The chaotic behavior of the Mixmaster universe is related to the Kasner relations.

The cosmological constant and cosmological change

Physics Today, 1977
Is the Universe of infinite extent, or is it a finite system? Will it expand forever, or will it reach some maximum size before turning and collapsing upon itself like an inverse Big Bang? Just a few years ago, models of the conventional Friedman types were showing consistent, albeit tentative, evidence for an open, ever-expanding Universe. Since then,
