A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

A 2,000-page monograph series proposes a new conceptual framework connecting quantum physics, gravitation and cosmological evolution.

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 ...

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

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

A new study has estimated the universe’s possible age by using precise data on stars.

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.

The scientific study of cosmology, the field that focuses on the origins and evolution of the universe, is barely a century old. It has already been transformed more than once by new ideas, new ...

About 13.8 billion years ago, the origin of the universe began with the Big Bang. Scientists say all space, time, matter, and ...

Astronomers studying the Milky Way's oldest stars have estimated that the Universe is about 13.6 billion years old.

Researchers from the University of Bologna and the Leibniz Institute for Astrophysics Potsdam (AIP) along with other institutes have proposed a new way to address the Hubble tension by comparing ...
