Cosmologist Katie Mack breaks down what the latest findings about dark energy mean for our universe’s future. Either way, it ...

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

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

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

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

Physicist Richard Lieu first explored the idea that gravity could exist without mass—now he’s got a new cosmological model ...

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 ...

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

"The new model can account for both structure formation and stability, and the key observational properties of the expansion ...

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 ...

“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 ...
