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 ...

“Sometimes when I don’t know what to do, when I’m stressed or confused, I just play [Dark Souls 2] and stay in Majula,” wrote one viewer of a 10-hour Majula loop video. “Just hearing the ...

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 ...

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.

Together, the data match dynamical dark energy better than the standard picture, by a statistical measure as large as 4.2 sigma, depending on which data are used, the researchers report in a paper ...

Dark energy is one of the most mysterious features ... The current analysis reaches at most 4.2 sigma, but team member Mustapha Ishak-Boushaki at the University of Texas at Dallas says the team ...

Last April a survey by the Dark Energy Spectroscopic Instrument (DESI) published hints that dark energy may not be as constant as they’d assumed, adding to a pile of concerns that are already ...

Using the Dark Energy Spectroscopic Instrument ... The discrepancy between data and theory is at most 4.2 sigma (in the units of uncertainty preferred by physicists), representing one in 50,000 ...

Fresh data have bolstered the discovery that dark energy, the mysterious force that makes galaxies accelerate away from each other, has weakened over the past 4.5 billion years. The effect was ...
