WebbDark energy is a concept in modern cosmology that is best defined as the intrinsic energy in empty space, or “vacuum energy.” This energy contributes to an outward pressure that causes space to expand. In turn, the expansion creates more space, which then creates more dark energy, and thus expands space further and faster. Webb18 dec. 2024 · Dark energy and dark matter constitute 95% of the observable Universe. Yet the physical nature of these two phenomena remains a mystery. Einstein suggested a long-forgotten solution: gravitationally repulsive negative masses, which drive cosmic expansion and cannot coalesce into light-emitting structures.

Webb28 sep. 2024 · One theory suggests the existence of a “Hidden Valley”, a parallel world made of dark matter having very little in common with matter we know. If one of these theories proved to be true, it could help scientists gain a better understanding of the composition of our universe and, in particular, how galaxies hold together.
