Dark energy is one of the most mysterious features of our universe – we don’t know what it is, but it controls how the universe is expanding, as well as its ultimate fate. Now, a study of ...

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 ...

Dark energy makes up roughly 70% of the universe, yet we know nothing about it. Around 25% of the universe is the equally mysterious dark matter, leaving just 5% for everything that we can see and ...

The Dark Energy Spectroscopic Instrument (DESI) collaboration just dropped their first official data release, covering the first 13 months of the instrument’s operation. While many conclusions ...

Dark energy, the mysterious force thought to be driving the ever-faster expansion of the universe, appears to be changing over time, according to new observations released Wednesday. If dark ...

New hints from one of the most extensive surveys of the cosmos to date suggest that mysterious dark energy may be evolving in ways that could shift how astronomers understand the universe.

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 ...

Here’s how it works. New results from the Dark Energy Spectroscopic Instrument (DESI) suggest that the unknown force accelerating the expansion of the universe isn't what we believed it to be.

ANAHEIM, Calif. — Change is in the air. New data strengthen a hint that dark energy, long thought to be constant force in the universe, might change over time. Dark energy explains the observati ...

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 ...
