Is The Universe Finite?
Summary
PBS Space Time explores a new study claiming Planck satellite data reveals our universe is finite and positively curved, challenging the standard model of a flat, infinite cosmos. The episode details how gravitational lensing effects in the cosmic microwave background suggest higher energy density than previously thought, potentially resolving the Hubble tension. Hosts discuss the statistical confidence of these findings, possible systematic errors in data calibration, and the implications for dark energy. The segment concludes with listener questions on the anthropic principle and the doom…
