New measurements of a certain type of supernova seems to indicate that our expanding universe isn't accelerating at all, negating any need to invoke a mysterious 'dark energy' to explain supernovae ...

A new way to study 3D maps of galaxies in the cosmos without compressing the data is revealing new information about the dark universe.

Astronomers have discovered a cosmic superstructure so massive it reshapes our understanding of the universe's largest-scale ...

The Standard Model (SM), the main physics framework describing elementary particles and the forces driving them, outlines key ...

The Cosmological Principle is a fundamental hypothesis in cosmology. It postulates that the universe is homogeneous and isotropic on a large scale, meaning it looks the same in all directions and at ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead ...

With a length of 428 megaparsecs, or around 1.39 billion light-years, the superstructure is the biggest ever spotted.

A recent study published in The Astrophysical Journal has introduced a new theoretical model that explains astrophysical ...

For a long time, scientists have believed that the universe looks the same no matter where you are or which direction you ...

Lambda CDM is our standard model of Big Bang cosmology and accounts for much of what we see in the universe, like its large-scale structure. "We find superstructures with similar properties in ...

the model faces scrutiny. Critics argue that it lacks a definitive explanation for certain phenomena well-accounted for by inflation, such as the observed large-scale structure of the Universe.
