"There are more questions than answers at this point." Dark energy could have an accomplice that helps it slow the growth of large cosmic structures, such as vast superclusters made up of clusters ...

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.

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 ...

The universe has been expanding ever since the Big Bang almost 14 billion years ago, and astronomers believe a kind of invisible force called dark energy is making it accelerate faster. If the ...

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 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 ...

Recently, two major research groups—the Dark Energy Spectroscopic Instrument (DESI) and the Dark Energy Survey (DES)—have collected massive amounts of data by observing millions of galaxies.

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 ...

Scientists might have gotten dark energy totally wrong. According to a new analysis, dark energy might be changing in a way that challenges our understanding of the cosmos. Dark energy is the ...

If dark energy is in fact weakening, it would likely mean that science's understanding of how the universe works will need to be rewritten. The new findings come from the Dark Energy Spectroscopic ...
