It's a Vibe Baryon acoustic oscillations — fluctuations in the density of matter in the universe — started out tiny. Then, when the universe expanded, they grew to create the large-scale structure of the universe. For BBC, Patchen Barss explains what the fluctuations can tell us about inflation and dark energy.
