Abstract
Departures of the energy spectrum of the cosmic microwave background (CMB) from a perfect blackbody probe a fundamental property of the universe — its thermal history. We outline a program to improve current limits to spectral distortions by 3 orders of magnitude, testing the standard model and opening a vast discovery space for new physics.
