NASA’s Nancy Grace Roman Space Telescope, now scheduled for a September 2026 launch, is designed to attack the dark-energy ...

New DESI-inspired research suggests dark energy may evolve over time and cross the mysterious "phantom divide," potentially ...

A new theory suggests the universe is constantly recording its own history in the fabric of spacetime. If correct, this ...

The Dark Energy Survey Collaboration collected information on hundreds of millions of galaxies across the universe using the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the U.S ...

All the atoms and radiation in the universe make up less than 5 percent of its contents. The rest is composed of two invisible, enigmatic entities: dark matter and dark energy. Together they govern ...

Rolf Landauer showed that "information is physical" with every bit equivalent to a small amount of energy proportional to temperature. The Landauer equivalent energy of information carried, or ...

Our universe has been expanding ever since it was born in the Big Bang. For decades, most cosmologists believed the universe’s expansion was slowing. Gravity, pulling on all matter, would eventually ...

The great Russian physicist and Nobel laureate Lev Landau once remarked that “cosmologists are often in error, but never in doubt”. In studying the history of the universe itself, there is always a ...

One of the greatest mysteries in cosmology is the nature of what we refer to as dark energy. This mysterious force drives the expansion of the universe to accelerate. Dark energy is an unknown ...

Some 13.8 billion years ago, the universe began with a rapid expansion we call the Big Bang. After this initial expansion, which lasted a fraction of a second, gravity started to slow the universe ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

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 ...
