Episode Notes:

Welcome back to Cosmos in a Pod! I’m your host, Amitesh, and today we’re exploring one of the most profound discoveries in cosmology: the Cosmic Microwave Background (CMB). Often called the “afterglow of the Big Bang,” this faint radiation offers a glimpse into the universe’s infancy and holds the key to understanding its origins and evolution.

Episode Highlights:

  • A relic of the Big Bang, the CMB is a faint glow of radiation that fills the universe.
  • Originated about 380,000 years after the Big Bang when the universe cooled enough for neutral atoms to form, allowing light to travel freely.
  • Today, the CMB is observed in the microwave spectrum at just 2.7 Kelvin.
