A recent study by one scientist from the California Institute of Technology could change everything, however. Dr. Ranga-Ram Chary believes he may have found evidence that parallel universes have been bumping up against ours, like bubbles floating in a foam, and that these bumps have caused "bruises" that can be observed, reports New Scientist.
Chary looked for signs of these cosmic bumps in the Planck map of the cosmic microwave background (CMB), a map of the radiation leftover from the first few moments of our forming universe. It's a map that would look the same no matter where you're viewing it from in the universe; a blueprint, if you will, of the structure of the cosmos.
