Primordial gravitational waves have crucial implications for the origin of the universe and fundamental physics. Using currently available cosmic microwave background data from Planck, ACT and SPT separately or their combinations with BK18 B-mode polarization and DESI observations, we give the strongest constraints on primordial gravitational waves so far.
