The cosmic microwave background is the luminous echo of the primordial explosion, the Big Bang — literally the oldest light in the Universe. Exquisitely precise measurements of this light have allowed astronomers to achieve what might seem impossible: weighing the universe, and thereby establishing the geometry of space.
This lecture will explain the physics of the cosmic microwave background and the challenges in understanding where our universe came from.
