Cosmic background radiation

Cosmic Background Radiation (CMB) is the faint glow of microwave radiation evenly filling the universe, a remnant from the Big Bang that occurred about 13.8 billion years ago. As the universe expanded and cooled, this radiation was released and is now detected as a uniform background signal. CMB provides crucial evidence for the Big Bang theory, helping scientists understand the universe's early conditions and its ongoing expansion. By studying this radiation, researchers can learn about the formation of galaxies and the overall structure of the cosmos.

    Cosmic Background Radiation is the faint glow of radiation that fills the universe, a remnant from the Big Bang, which occurred about 13.8 billion years ago. It is essentially the afterglow of the hot, dense state of the early universe, now stretched and cooled as the universe expanded. Detected in every direction in space, this radiation provides vital evidence for the Big Bang theory and helps scientists understand the universe's origin, structure, and evolution. Its even distribution suggests a uniform early universe, making it a crucial element in the study of cosmology.
