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 ...

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

The new findings come from the Dark Energy Spectroscopic Instrument (DESI), which sits on a telescope at the Kitt Peak National Observatory in Arizona.
