Three forces, one model: The Standard Model explained - Interesting Engineering

A Physicist’s blog on Instagram: "The link between quantum vacuum fluctuations and the CMB is that tiny quantum fluctuations in the inflaton field during inflation were rapidly stretched to cosmological sizes, turning microscopic quantum noise into macroscopic density variations. When inflation ended, these variations became small over- and under-densities in the early universe’s plasma. As photons decoupled at recombination, these density variations were imprinted as the temperature anisotropie
