Dark energy, the mysterious driver of the accelerated cosmic expansion, remains one of the foremost challenges in modern cosmology. Originally encapsulated by the cosmological constant (Λ), ...

Research led by the Tata Institute of Fundamental Research, Mumbai along with Professor Subir Sarkar from the University of Oxford questions the widely accepted argument that the expansion rate of the ...

The results add to evidence that dark energy, the unknown component believed to drive that expansion, may evolve rather than ...

Constraints on the present expansion rate of the universe have only improved with new methods and a better understanding of ...

For thousands of years, humanity viewed the skies as unchanging, except for a few "wandering stars" (that we now know are planets). As we improved our ability to perceive the cosmos with ...

Article SummaryA latest study reanalyzing data from over 1,700 Type Ia supernovae has cast doubt on the conventional theory regarding the accelerated expansion of the universe and the existence of ...

If we are located in a region with below-average density such as the green dot, then matter would flow away from us due to stronger gravity from the surrounding denser regions, as shown by the red ...

Recent discoveries in cosmology have left scientists scratching their heads, as they challenge our fundamental understanding of physics. The universe’s expansion rate, the balance between matter and ...

That the universe is expanding has been known for almost a hundred years now, but how fast? The exact rate of that expansion remains hotly debated, even challenging the standard model of cosmology. A ...

Dark matter is often portrayed as a cosmic loner, interacting with itself and the rest of the universe only through gravity. But what if dark matter particles also exert a hidden force on one another?
