   In physical cosmology and astronomy, dark energy is an unknown form of energy that affects the universe on the largest scales. Its primary effect is to drive the accelerating expansion of the universe. Assuming that the lambda-CDM model of cosmology is correct, [1] dark energy is the dominant component of the universe, contributing 68% of the ...

   Does dark energy exist?

   • Astrophysicist Ethan Siegel states that, while such alternatives gain mainstream press coverage, almost all professional astrophysicists are confident that dark energy exists and that none of the competing theories successfully explain observations to the same level of precision as standard dark energy.

   What is the density of dark energy?

   • Dark energy's density is very low: 7 × 10−30 g/cm3 ( 6 × 10−10 J/m3 in mass-energy ), much less than the density of ordinary matter or dark matter within galaxies. However, it dominates the universe's mass–energy content because it is uniform across space.

    May 3, 2024 · DESI, a new observational project, has produced some of the biggest maps ever made of the Universe, spanning 11 billion years of cosmic history. The results suggest that dark energy, the repulsive force that drives cosmic acceleration, could be varying over time, challenging the standard ΛCDM model.
