For decades, scientists have believed that the Universe is expanding at an ever-accelerating pace due to a mysterious force ...

Korean scientists studying Type Ia supernovae have found strong evidence that the universe's expansion is not accelerating, ...

A remarkable new study challenges the findings of Nobel Prize-winning research into how our universe has changed over time.

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

Cosmology is already a complicated field of study, so switching up the variables is extra rough.

The Big Bang theory has dominated our understanding of the universe’s origin for almost 100 years. It describes a moment when ...

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...

The clearest pictures yet of the newborn cosmos strengthen the prevailing model of the universe but deepen a mystery about its expansion rate. Measurements of this rate, known as the Hubble constant, ...

DESI's 3D map of our universe. The Earth is at the central vertex, and every dot is a galaxy. DESI collaboration and KPNO/NOIRLab/NSF/AURA/R. Proctor Share The great ...

Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...
