The nature of dark energy is more hypothetical than that of dark matter, and many things about it remain in the realm of speculation. Dark energy is thought to be very homogeneous and not dense, and is not known to interact through any of the fundamental forces other than gravity.
Feb 5, 2024 · Learn how dark energy was discovered, what it is, and how it affects the cosmic expansion. Explore the history of the universe from the big bang to the present day, and the evidence for dark energy from supernovae, redshift, and more.
Nov 24, 2022 · The dominating form of energy in the cosmos dark energy is driving the accelerating expansion of the universe, but its nature remains a mystery.
Matter is defined as any substance that has mass and occupies space. But there’s more to the universe than the matter we can see. Dark matter and dark energy are mysterious substances that affect and shape the cosmos, and scientists are still trying to figure them out. Learn more.
May 25, 2024 · Dark energy is a repulsive force that dominates the universe and accelerates its expansion. Learn how it was discovered, how it affects the formation of galaxies and clusters, and what are its possible explanations.

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.
Mar 3, 2020 · Learn how dark matter and dark energy are different forms of invisible matter and energy that dominate the universe. Find out how they affect the cosmic expansion, galaxy clusters, and supernovas.
