Changing, not constant The idea that dark energy might be changing over time is more than a provocative twist; it addresses one of the deepest puzzles in modern physics.

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.

New research suggests sub-stellar objects called dark dwarfs could glow forever on dark matter energy. Could they reveal secrets about the universe’s hidden mass?

New observations of the cosmos show that the dark energy, a mysterious force that accelerates the expansion of the universe, is evolving.

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 may not be constant—this discovery could undermine our entire model of cosmological history by Bernard J.T. Jones, Licia Verde, Vicent J. Martínez and Virginia L Trimble, The ...

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 ...

Einstein called it his “biggest blunder.” Now a Berkeley Lab breakthrough is shedding light on the mysteries of dark energy and cosmic expansion Berkeley Laboratory released new findings that ...

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string theory,' a new preprint suggests.

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. This ...
