Dark energy has been a mysterious element of cosmological equation since it was proposed three decades ago, but new research ...

Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a ...

The universe may not be perfectly uniform after all, a new series of papers hints. If confirmed, this could upend a nearly 100-year-old model of cosmology.

Our best model of the cosmos has a glaring mathematical problem, but we may have found an answer.

The James Webb Space Telescope (JWST) was designed to look back in time and study galaxies that existed shortly after the Big Bang. In so doing, scientists hoped to gain a better understanding of how ...

Kanazawa, Japan - The expansion of the Universe has occupied the minds of astronomers and astrophysicists for decades. Among the cosmological models that have been suggested over the years, Lambda ...

It's hard to get a sense of the scale of the universe from our little corner of it, but scientists realized decades back that the universe is expanding. This naturally led to questions about the ...

Emergent cosmological models propose a universe without an initial singularity, in which the cosmos originates from a past-eternal static or quasi-static state that subsequently evolves into standard ...

Conventional cosmology rests on the assumption of large-scale homogeneity and isotropy as enshrined in the Friedmann–Lemaître–Robertson–Walker framework. Inhomogeneous cosmological models relax this ...

Our ideas about the Universe are based on a century-old simplification known as the cosmological principle. It suggests that when averaged on large scales, the Cosmos is homogeneous and matter is ...

The James Webb Space Telescope (JWST) was designed to look back in time and study galaxies that existed shortly after the Big Bang. In so doing, scientists hoped to gain a better understanding of how ...

A holographic cosmological model with a power-law term has been proposed by a researcher to study thermodynamic properties on the horizon of the Universe. This model was found to satisfy the second ...
