Dark energy makes up roughly 70% of the universe, yet we know nothing about it. Around 25% of the universe is the equally mysterious dark matter, leaving just 5% for everything that we can see and ...

Dark energy has long been considered the main explanation for the accelerated expansion of the universe. However, a new international study based on the largest and most homogeneous catalog of Type Ia ...

Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe’s greatest mysteries. The most widely accepted theory currently suggests ...

Our current cosmological model—known as lambda cold dark matter, or ΛCDM—relies on hypothesized dark energy to explain the accelerating expansion of the universe. However, one competing theory known ...

Astronomers have combined nearly 2,900 exploding stars into the largest standardized supernova dataset yet assembled, and the result deepens a problem for the model that has anchored cosmology for a ...

Physicists propose that a mysterious force known as early dark energy could solve two of the biggest puzzles in cosmology and fill in some major gaps in our understanding of how the early universe ...
