WebbIf fluctuations in the distribution of matter in the primordial Universe have equal power on all spatial scales, cosmologists say that their power spectrum is 'scale-invariant'. This is characterised with a parameter known as the spectral index, n_s. For a perfectly scale-invariant spectrum, n_s = 1. If n_s is smaller than 1, it means that ... 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.
