String theory has long been touted as physicists' best candidate for describing the fundamental nature of the universe, with ...

The Rubin Observatory will reveal its first images on Monday. Space.com spoke to scientists who explained why this will be a ...

that the dark energy could be varying with cosmic time. That said, scientists are trained to be skeptical, and there are many ...

"A priori, I would not have expected the abundance of JWST's early bright galaxies to have anything to do with early dark energy, but their observation that EDE pushes cosmological parameters in a ...

Dark energy explains the observation that the universe’s expansion rate is accelerating. But its origins are unknown. It’s typically expected to have constant density across the billions of ye ...

Alas, anytime we try to come up with a modification to general relativity to wipe away dark energy, we end up violating some other observation. It doesn’t mean that a more complete understanding ...

This hunch would later be confirmed by the observation that our universe’s expansion is accelerating. Heritage Images/Hulton Archive/Getty Images What is dark energy made of? Because scientists ...

Dark energy isn’t just dark — it's nigh invisible. Hypothesized by physicists to drive the accelerating expansion of the universe, dark energy has never been directly observed or measured.

This observation was attributed to the mysterious quantity called dark energy. Einstein’s concept of the cosmological constant could actually explain dark energy if it had a positive value ...

“That is dark energy.” These Waves Could Reveal the ... and so on — the observation of gravitational waves reveals events and objects that occurred in the universe’s distant past.

This observation suggested that something other than the Big Bang was pushing the universe to grow. Something that they called “dark energy” must also play a cosmically vital role; while dark matter ...
