Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark discovery, potentially providing a significant clue to some of our most basic, big-picture scientific questions about the Universe. In this white paper, we survey the leading early-Universe mechanisms that may produce a detectable signal – including inflation, phase transitions, topological defects, as well as primordial black holes – and highlight the connections to fundamental physics. We review the…
