New observations of the cosmos show that the dark energy, a mysterious force that accelerates the expansion of the universe, is evolving.

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

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

Cosmologist Katie Mack breaks down what the latest findings about dark energy mean for our universe’s future. Either way, it won’t be happy.

When taken in isolation, the DESI findings don't actually challenge the picture of dark energy developed in the LCDM model. It is when the DESI data is compared with other measurements of the ...

The universe’s expansion is accelerating, not decelerating. Our understanding of how the universe works may need an update.

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 ...

Instead, it appears to be weakening at the moment, and in the past it seems to have existed in an extreme form known as “phantom” dark energy. The new findings have the potential to change everything ...

If anything, checking DESI findings with data from BOSS has left the team with a larger mystery on their hands. Whatever dark energy is, be it the cosmological constant or something else ...

A few days ago, a new press release announced groundbreaking findings from the Dark Energy Spectroscopy Instrument (DESI), which is installed on the Mayall Telescope in Arizona. This vast survey ...

“These new measurements offer the strongest evidence so far that dark energy evolves, which would be another mind-blowing change to our understanding of how the universe works.” The findings ...
