Smallest matter in the universe
Webb24 jan. 2014 · Most cosmologists believe that the galaxies that we observe today grew from the gravitational pull of small fluctuations in the nearly-uniform density of the early universe. These fluctuations leave an imprint in the cosmic microwave background radiation in the form of temperature fluctuations from point to point across the sky.

Webb8 jan. 2024 · However, dark matter might be some sort of unknown subatomic particle that interacts weakly with normal matter. A popular theory holds that dark matter particles don't move very fast, which makes it easier for them to clump together. According to this idea, the universe contains a broad range of dark matter concentrations, from small to large. Webb19 aug. 2024 · The universe is estimated to be made up of 4.9% ordinary (baryonic) matter, 26.8% dark matter, and 68.3% dark energy.
