As if dark energy weren't already mysterious and baffling enough, new research suggests that this unknown force may not be ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By ...

A new study is implying that the universe may actually be slowing down and that the culmination of the decrease in dark ...

Cosmology is already a complicated field of study, so switching up the variables is extra rough.

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously ...

Dark energy and black holes are two of the most mysterious topics when it comes to space, but they might actually be linked. And causing the universe to expand.

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy Spectroscopic Instrument (DESI)—namely that the dark energy, rather than being ...

In 2024 a shockwave rippled through the astronomical world, shaking it to the core. The disturbance didn’t come from some astral disaster at the solar system’s doorstep, however. Rather it arrived via ...

The latest Dark Energy Spectroscopic Instrument results fall short of the discovery threshold but strengthen evidence for dynamical dark energy. Last year, we reported on an exciting hint of new ...

Last spring, a team of nearly 1,000 cosmologists announced that dark energy — the enigmatic agent propelling the universe to swell in size at an ever-increasing rate — might be slackening. The ...
