Description
In arXiv:2207.05765 we collated an emerging science case challenging the second most fundamental cosmological assumption that there is a global Friedmann-Lemaitre-Robertson-Walker (FLRW) spacetime describing the Universe. FLRW is not a fundamental symmetry of Nature, but rather a working approximation for a physical system, so nothing prevents it from breaking down at any given precision. I will argue that this breakdown may be happening today.
