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 ...

Perlmutter, Riess, and Schmidt attributed this deviation to Einstein's cosmological constant, which is represented by the Greek letter Lambda, Λ, and is related to the deceleration parameter. Their ...

A bold new theory suggests the universe didn’t begin with a single Big Bang, but instead unfolds through a series of ultra-fast, invisible bursts called “temporal singularities.” These fleeting events ...

A new analysis of astronomical data suggests unknown physics is at work assisting dark energy in acting almost as "antigravity," undoing the work of gravity, which clumps together matter to build vast ...

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

(Courtesy: Marilyn Sargent/Berkeley Lab) The first results from the Dark Energy Spectroscopic Instrument (DESI) are a cosmological bombshell, suggesting that the strength of dark energy has not ...

While many conclusions were drawn from this data, one stood out—dark energy may not be a cosmological constant after all. In fact, its effects on the universe may be weakening over time.
