SUMMARY
The cosmic microwave background (CMB) is a remnant radiation from the Big Bang, detected as noise by Arno Penzias and Robert Wilson in the 1960s. This noise arises from microwave photons, similar to how AM/FM radios pick up radio spectrum photons. The CMB represents a significant aspect of cosmology, providing insights into the early universe and its evolution. Understanding the nature of this noise is crucial for grasping the fundamental principles of cosmic radiation.
