If the cosmos is lopsided, the foundation of modern cosmology starts to look a little shaky.

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make up nearly 70% of the cosmos, has been the leading explanation. But a new ...

A recent paper claimed that dark energy might not exist. But new research suggests this conclusion was premature.

WASHINGTON, June 16 (Reuters) - Taking a fresh look at data involving a specific type of stellar explosion, a team of researchers says it has confirmed the long-accepted notion that the universe is ...

Two of the biggest physics breakthroughs during the last decade are the discovery that wispy subatomic particles called neutrinos actually have a small amount of mass and the detection that the ...

In 1998, scientists discovered that our universe expands with acceleration, and in order to explain this effect, the concept of dark matter was introduced. This is a special type of energy that fills ...

Certain types of supernovae, or exploding stars, are more diverse than previously thought, a University of Arizona-led team of astronomers has discovered The results, reported in two papers published ...

Studying Type Ia supernovae – violent, luminous white dwarf star explosions – led to the Nobel Prize-winning discovery that the universe’s expansion is accelerating. This image combines data from four ...

Cosmologists have long assumed that our expanding universe is isotropic, meaning it looks the same when viewed from any angle. Researchers found that there were errors in some of these previous ...

The accelerating universe as a research area investigates the observed late-time acceleration of cosmic expansion and its implications for fundamental physics and cosmology. It encompasses precise ...
