Scientists are homing in on the nature of a mysterious force called dark energy, and nothing short of the fate of the universe hangs in the balance. The force is enormous — it makes up nearly 70 ...

Now, recent findings released March 19 from two of the largest cosmological surveys to date - the Dark Energy Spectroscopic Instrument (DESI) survey and the Dark Energy Survey (DES) - challenge ...

In the world of next-generation energy, researchers are taking a leap beyond chemistry into the strange rules of quantum ...

Brown dwarfs are too small to sustain the nuclear fusion that powers most stars, so they cool and fade over time. But if they ...

Dark energy, a mysterious force that scientists believe is behind the accelerated expansion of the universe, is weakening — which could result in the universe over the course of billions of ...

New evidence suggests the universe might not behave as expected, raising questions about the costs of being wrong.

Cosmologist Katie Mack breaks down what the latest findings about dark energy mean for our universe’s future. Either way, it won’t be happy. Dark Energy Spectroscopic Instrument (DESI ...

The Dark Energy Spectroscopic Instrument at Kitt Peak National Observatory in Arizona is operated imaging the night sky in 2022, in Kitt Peak, Arizona, U.S. Kitt Peak National Observatory/NOIRLab ...

Columnist and Physics How dark energy findings may inspire a new generation of physics nerds. The discovery of the cosmic acceleration problem truly inspired me as a teenage physics nerd.

In the wake of bombshell findings that suggest dark energy might be weakening as the universe expands, physicists are considering replacing the standard cosmological model of the universe with ...

Recent findings from the DESI and DES cosmological surveys challenge the long-held assumption of a constant dark energy density, suggesting instead that it may vary over cosmic time.
