A new theory published late last year is offering an explanation as to why our universe is expanding at an accelerating rate.

Astronomers have been confounded by recent evidence that the universe expanded at different rates throughout its life. New findings risk turning the tension into a crisis, scientists say.

A unique dataset of Type Ia supernovae being released today could change how cosmologists measure the expansion history of ...

If scientists confirm an anisotropic expansion, it would challenge the assumption that the universe has no preferred directions.

A new study published in the Journal of Cosmology and Astroparticle Physics (JCAP) presents a methodology to test the ...

The Vera C. Rubin Observatory is set to revolutionize our understanding of the cosmos by detecting millions of exploding ...

The Universe is expanding faster than predicted by theoretical models, and faster than can be explained by our current understanding of physics. This discrepancy between model and data became ...

The model described by the researchers is set in the backdrop of an expanding universe that is accelerating in its expansion, just like the modern-day universe is. In that expanding universe ...

The universe started expanding from a hot dense state known as the Big Bang ... but we still do not fully understand its interplay with the Standard Model of Particle Theory that Weinberg did so much ...

The model isn't perfect. It still assumes something about the early universe — namely, that the cosmological constant is strong enough to lead to a rapidly expanding cosmos. And it doesn't ...

A unique dataset of Type Ia Supernovae being released today could change how cosmologists measure the expansion history of the Universe.
