Largest dark energy map could reveal the fate of the universe
A modified telescope in Arizona has produced an interim map, which is already the largest three-dimensional map of the universe ever — and the instrument is only about a tenth of the way through its five-year mission. The Dark Energy Spectroscopic Instrument (DESI), a collaboration between Lawrence Berkeley National Laboratory...
What Is dark energy?

What Is dark energy?
Dark energy is an enigmatic phenomenon that acts in opposition to gravity and is responsible for accelerating the expansion of the universe. Though dark energy constitutes up to three-fourths of the mass-energy of the cosmos, its underlying nature has eluded physicists for decades. Dark energy has no real connections to...

Dark energy could lead to a second (and third, and fourth) Big Bang, new research suggests
Will the universe end in a bang or a whimper? A pair of theoretical physicists have proposed a third path: perhaps the universe will never end. In a study that attempts to define the nature of dark energy — a mysterious phenomenon thought to be causing the universe to expand...

The expansion of the universe could be a mirage, new theoretical study suggests
The expansion of the universe could be a mirage, a potentially controversial new study suggests. This rethinking of the cosmos also suggests solutions for the puzzles of dark energy and dark matter, which scientists believe account for around 95% of the universe's total energy and matter but remain shrouded in...
