There is growing controversy over recent evidence suggesting that a mysterious force known as dark energy might be changing in a way that challenges our current understanding of time and space. An ...

Dark energy remains one of the most stubborn puzzles in modern science. Despite decades of observation and increasingly powerful telescopes, its true nature is still unknown. Now, scientists involved ...

The Dark Energy Survey collaboration is releasing results that, for the first time, combine all of the data from an intensive six-year mapping of galaxies in the universe. The new analysis, of ...

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

The accelerating expansion of the universe is usually explained by an invisible force known as dark energy. But a new study suggests this mysterious ingredient may not be necessary after all. Using an ...

After five years of mapping the sky in 3D — an area that stretches from Earth’s front porch to about 11 billion light-years away — researchers at the Dark Energy Spectroscopic Instrument (DESI) ...

Adam Riess takes us inside the discovery of dark energy. What does it feel like to make one of the biggest discoveries in physics? Adam Riess knows — because his work revealed that the universe isn’t ...
