Question

Quizplus · Accepted Answer

The discovery of cosmic microwave background radiation provided strong observational evidence in support of the Big Bang theory. The theory predicted the existence of the cosmic microwave background radiation, which is a remnant of the hot, dense state of the early universe. Its discovery in 1964 by Penzias and Wilson confirmed the theory's prediction and bolstered its status as the most widely accepted model for the origin and evolution of the universe.
