Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...

Last month, the Dark Energy Spectroscopic Instrument (DESI) collective reported that dark energy is evolving—specifically weakening—and it could help provide the first observational evidence of string ...
