Quizplus · Accepted Answer

The persistent noise detected by Penzias and Wilson at a wavelength of 1 mm came from all directions in the sky and was discovered to be photons left over from the Big Bang, known as the cosmic microwave background radiation. This discovery helped provide strong evidence for the Big Bang theory of the origin of the universe.
