WebbLarge clusters of stars soon became the first galaxies. The Hubble Space Telescope and powerful ground-based telescopes are now beginning to find galaxies that were created about one billion years after the Big Bang. These small galaxies were much closer together than galaxies are today. Collisions were common. Webb30 maj 2024 · Computer simulations helped develop that theory. In the 1980s they showed that to form clumps large enough to bind the observed clusters of galaxies, dark matter particles had to be slow moving and cold. The basic theory, which assumes a cosmological constant, became known as Λ cold dark matter (ΛCDM).
