Cosmic voids may seem like the emptiest places in the universe, stripped of matter, radiation, and even dark matter. But they’re far from nothing. Even in these vast empty regions, the fundamental quantum fields that fill all of space remain, carrying a small but real amount of energy known as vacuum energy, or dark energy. While this energy is overwhelmed by matter in galaxies and clusters, in the deep emptiness of cosmic voids it becomes domin…

Astronomers Say the “Empty” Voids of Space May Be Full of Hidden Energy

Astronomers Say the “Empty” Voids of Space May Be Full of Hidden EnergyCosmic voids are the largest structures in the universe — enormous regions between galaxies that appear almost completely empty. But modern physics shows that even these vast spaces are not truly empty.
