Not everything we knew about the universe is wrong. But not not everything. The Dark Energy Spectroscopic Instrument (DESI) collaboration just dropped their first official data release, covering the ...

Gravity pulls us to earth, a lesson you learn viscerally the first time you fall. Isaac Newton described gravity as a ...

Astronomers thought dark energy was a constant. But now, findings from the Dark Energy Spectroscopic Instrument provide even more evidence that it may be fluctuating ...

Physicists have proposed a new model of space-time that may provide the 'first observational evidence supporting string theory,' a new preprint suggests.

DESI's findings also bolster another big theory among some astronomers – that the universe is going to end with a "big crunch." While dark energy is weakening, according to Ishak, matter is not.

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 ...

The findings suggest that dark energy is dynamic and changes over time, and that it used to be stronger in the early stages of the universe but is weaker now. That’s particularly odd because ...

First discovered in the 1990s, dark energy has come to feel like a familiar face of the cosmos. Astronomers first imagined ...

so they call it dark energy. It is so vast it is thought to make up nearly 70% of the universe — while ordinary matter like all the stars and planets and people make up just 5%. But findings ...

The updated findings come from an international research ... Get the latest breaking news as it happens. Called the Dark Energy Spectroscopic Instrument, the collaboration released its first ...
