Mathematicians are challenging the idea that dark energy is responsible for the accelerating expansion of the universe. In a ...

Dark energy has been a mysterious element of cosmological equation since it was proposed three decades ago, but new research ...

Is dark energy getting weaker explained and what that could mean for the expansion of the universe #space #science #cosmology ...

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 ...

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 ...

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 ...

Anyone who has been paying attention to cosmology over the past few years is aware of problems with our best attempts to ...

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 universe may not only be geometry and energy—but also memory. And in that memory, every moment of cosmic history may still be written. For more than a century, physics has been built on two great ...

Ask most astronomers, and they’ll tell you that dark matter and dark energy make up more than 95 percent of the universe and that they are the explanations for many of the large-scale phenomena we ...
