Welcome back to Cosmos in a Pod! I’m your host, Amitesh, and today we’re tackling one of the most fundamental questions in cosmology: how do we know the universe is 13.8 billion years old? Let’s explore the tools and techniques astronomers use to measure the age of everything we see.

Episode Highlights:

The Cosmic Microwave Background (CMB)

  • The faint afterglow of the Big Bang, first detected in 1965, provides a snapshot of the universe 380,000 years after its birth.
  • Missions like Planck analyze temperature fluctuations in the CMB to calculate the universe’s age and expansion history.

The Hubble Constant

  • Describes the rate of the universe’s expansion, discovered by Edwin Hubble in 1929.
  • Redshift measurements and distances to galaxies, observed  ...
