Final answer:
The map of the CMB shows temperature variations which are the result of fluctuations in radiation from the Big Bang, and these variations represent the seeds of all future structures in the universe.
Step-by-step explanation:
The map of the Cosmic Microwave Background (CMB) shows fluctuations, or wrinkles, in the radiation from the Big Bang. These fluctuations are represented by variations in temperature across the map. Red areas indicate higher temperature and density, while blue areas indicate lower temperature and density. These temperature variations are thought to be the seeds of all future structures in the universe, such as stars, galaxies, and galaxy clusters.
