What Sits at the Exact Center of the Universe?

What sits at the exact center of the universe? This video traces how our idea of the cosmic center changed—from Aristotle’s Earth-centered universe and Copernicus moving the focus to the Sun, to Hubble’s expanding universe and the discovery of the cosmic microwave background. We explore why the Big Bang wasn’t an explosion from one location, how space itself expands, and what observations from WMAP and Planck tell us about the universe’s geometry. We also look at inflation, the CMB Cold Spot, cosmic topology, and the mysteries that could still change our understanding of the universe.
