The podcast episodes provided cover various aspects of the Big Bang theory and the early universe, including the matter-antimatter asymmetry, cosmic inflation, the cosmic microwave background, the formation of the first stars and galaxies, and recent observations that challenge our current cosmological models.

For example, episode 3 mysteries of the universe - and a new force that might explain them | Alex Keshavarzi discusses how the Muon g-2 experiment at Fermilab could provide evidence of new particles or forces beyond the Standard Model, which could help explain mysteries like dark energy, dark matter, and the matter-antimatter asymmetry in the universe.

Episode Ep. 3: The Dark Ages of the Cosmos and Ep. 1: The First Fraction of a Second from the Crash Course Pods: The Universe podcast delve deeply into the early history of the universe, covering topics like cosmic inflation, the cosmic microwave background, and the formation of the first stars and galaxies.

The podcast episodes also touch on more recent observations, such as those from the James Webb Space Telescope, which have revealed unexpectedly large and mature galaxies in the early universe, challenging our current cosmological models, as discussed in the What the Hell Is at the Edge of Space? episode of Science Vs.
