Scientists claim to find 'first observational evidence supporting string theory,' which could finally reveal the nature of dark energy

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 calculations suggest that, at the smallest scales, space-time behaves in a profoundly quantum way, differing drastically from the smooth, continuous structure we experience in everyday life. According to their findings, the coordinates of space-time do not "commute" — meaning the order in which they appear in equations affects the outcome. This is similar to how a particle's position and velocity behave in quantum mechanics.
