Cosmic Microwave Backgrround (CMB) experiments have contributed powerful constraints on the fundamental physics of the Universe.  Upcoming CMB experiments such as the Simons Observatory and CMB-S4 are poised to extend this progress even further.  However, CMB experiments still have a wealth of information to offer beyond near-term facilities regarding the properties of dark matter, inflation, and light relic particles.  In particular, a much lower-noise and higher-resolution wide-area CMB survey can cross a number of critical fundamental physics thresholds and open a relatively untapped window of small-scale, late-time CMB anisotropies.  Here I will discuss CMB-HD, a next-generation CMB facility with three times lower noise and six times higher resolution than the CMB-S4 wide-area survey, as well as the discoveries it can enable.
