Evidence suggests that we are suspended in a cosmic sea of dark matter, a mysterious substance that shapes galaxies and large structures in the universe but is transparent to photons, the carriers ...

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 ...

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 ...

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.

A new study using the Dark Energy Survey (DES) final datasets suggests potential inconsistencies in the standard cosmological model, known as ΛCDM. If confirmed, these findings could ...

Some scientists think so, but others have challenged the claim that so-called "dark oxygen" is being produced in the lightless abyss of the seabed. The discovery -- detailed last July in the ...

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 ...

But a separate recent result reinforces it. Using the Dark Energy Spectroscopic Instrument, or DESI, scientists have assembled the largest three-dimensional map of the universe to date.

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 ...

I’m overwriting. I’ve just reread Upton Sinclair’s “The Jungle,” and its prose, lurid and yet somehow plodding, has worked its way into my mind. But what an important novel it was ...

The number of migrants trying to reach the US by trekking through the jungle to Central America plunged 99% last month, potentially improving strained relations between Panama and US President ...
