Researchers at Durham and collaborators in the Dark Energy Spectroscopic Instrument (DESI) mission have proposed a bold new ...

A new interpretation of dark energy data suggests that the mysterious force, which accelerated the early universe's expansion ...

Dark energy, the mysterious force driving the accelerated expansion of the universe, has puzzled scientists since its ...

Cosmic maps appear consistent with the proposal that black holes could cause the Universe's accelerating expansion.

The universe is expanding, and that expansion is thought to be driven by unseen dark energy, but new measurements indicate ...

A collaboration involving a Rutgers University-New Brunswick cosmologist, along with hundreds of other researchers and dozens ...

A new study may have found a link between dark energy and the Second Law of Thermodynamics—suggesting that the very expansion of the universe may impart a direction to time.

Dark energy’s long history Scientists determine dark energy has been present in the universe for some 9 billion years, most of the cosmos' lifetime. Provided by STScI, Baltimore, Maryland ...

Well before we conceived of dark energy, all the way back in the 1920s and 1930s, scientists derived how the entire Universe could have evolved within General Relativity.

They concluded that a source of energy, dubbed "dark energy" because it remains unseen, is responsible for the push. The elusive energy makes up about 68 percent of the total energy of the universe.

Locked in a cosmic tug of war, dark energy (purple) pushes the universe apart, while gravity (green) pulls it together. At the moment, dark energy is winning. Image credit: NASA/JPL-Caltech. This is ...

For dark energy, the pressure is actually equal to the negative of the energy density, so that the second derivative of the scale factor (which determines acceleration vs. deceleration) flips in ...
