The CMB: the most important discovery in cosmic historyThe cosmic microwave background (CMB) is a crucial discovery that shaped our understanding of the early Universe and validated the Big Bang theory.
What the "background noise of the universe" tells us about spacetime's originsThe Big Bang is not a specific moment but a period of time, as explained by scientists discussing the cosmic microwave background.
Ask Ethan: Does the CMB really "prove" the Big Bang?The CMB is considered strong evidence for the Big Bang theory, despite contrarian views that challenge its cosmological origin.
Arno Penzias obituaryArno Penzias discovered cosmic microwave background, revolutionizing cosmology and challenging prevailing theories.

Latest James Webb data hints at new physics in Universe's expansionThe latest JWST data suggests discrepancies in the Hubble Constant are likely due to new physics rather than measurement errors.
Ask Ethan: How does the Universe's temperature change over time?The Universe has evolved from a hot, uniform state to a cooler, structured one over billions of years.
