Listen to a Podcast About Cosmology

Explore the origin, evolution, and ultimate fate of the universe. From the Big Bang and cosmic inflation to dark energy, multiverse theories, and the arrow of time.

The Big Bang occurred approximately 13.8 billion years ago, a figure determined with remarkable precision by combining data from the cosmic microwave background radiation (CMBR), the distribution of galaxies, and the expansion rate of the universe. The CMBR itself was accidentally discovered in 1964 by Arno Penzias and Robert Wilson at Bell Labs, who initially mistook the persistent microwave noise in their antenna for pigeon droppings before realizing they had detected the thermal afterglow of the Big Bang — a discovery that earned them the 1978 Nobel Prize. One of cosmology's most active debates concerns the Hubble constant (the rate of cosmic expansion), with measurements from the early universe via the CMBR giving a value of about 67.4 km/s/Mpc while nearby supernova measurements yield roughly 73 km/s/Mpc — a discrepancy known as the "Hubble tension" that may point to entirely new physics beyond the standard cosmological model.
