Physicists are scrambling to understand why dark energy is weakening. In a surprising twist, we must now reconsider the ...

Ripples in the fabric of space-time called gravitational waves may be the key to solving the Hubble tension — one of the biggest nagging problems in physics.

A closer look at the Lambda Cold Dark Matter model, its core components, supporting evidence, and why new observations are ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

An extraordinarily rare, gravitationally lensed supernova may offer a powerful new way to measure the universe’s expansion rate.

New Analysis of Gravitational-Wave "Dark Sirens" Reveals Tension with General RelativityHONOLULU, Feb. 13, 2026 / PRZen ...

What if the Universe were not symmetrical? This idea, which goes against what scientists have long believed, emerges from new studies on large cosmic structures. Instead of being uniform in ...

There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on ...
