The universe is expanding at an accelerated rate and our current best theories to explain this is a mysterious form of energy called "dark energy" that by its very existence is pushing the universe to ...

In isolation, DESI’s 15 million galaxies could match either an evolving dark energy model or the standard theory of cosmology, known as the Lambda-CDM model, which assumes a cosmological constant.

Dr. Richard Lieu, a physics professor at The University of Alabama in Huntsville (UAH), a part of The University of Alabama ...

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.

The universe’s expansion is accelerating, not decelerating. Our understanding of how the universe works may need an update.

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 ...

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 ...

Physicists have proposed a new model of space-time based on string theory to explain dark energy. Their hypothesis suggests ...

DESI maps distant objects to study dark energy. The instrument is installed on the Nicholas U. Mayall 4-meter Telescope, shown here beneath star trails. (Credit: KPNO ...

The rest is made up of 25% dark matter and 70% dark energy. Dark matter is already a mysterious phenomenon, being made of presumably particles that don’t interact with light, but dark energy is ...

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 ...
