Breakthrough cosmic findings may challenge a century-old universe theory

A New Perspective on the Universe’s Structure A new set of cosmological studies is challenging one of the most fundamental assumptions in modern physics: that the universe behaves uniformly on the largest scales. Researchers have found tentative signs that the geometry of the cosmos may deviate from the long-standing framework that has guided cosmology for nearly a century. These findings, detailed in papers available on the preprint server arXiv, could point toward previously unknown physical effects shaping the evolution of the universe.

The Foundational Model of the Universe Faces New Questions Modern cosmology is built on the Friedmann-Lemaître-Robertson-Walker (FLRW) model, which assumes that, when viewed at sufficiently large scales, the universe is both homog...
