AB - New fundamental particles at the mass scale of a few TeVc<sup>-2</sup> could account for observed phenomena that cannot be explained by the standard model (SM) of particle physics, including the microscopic origin of dark matter and the macroscopic imbalance of matter over antimatter in the Universe. However, no beyond-the-SM (BSM) particles at the TeV scale have yet been detected at the Large Hadron Collider (LHC). With recent innovations, searches for time-reversal symmetry (T) violation through low-energy precision measurements of electric dipole moments (EDMs) of atoms and molecules have attained the sensitivity to detect indirect signatures of certain particles with masses of more than  10 TeVc<sup>-2</sup>. In this Perspective, we discuss recent developments in the measurement and interpretation of EDMs, and assess proposed techniques for future experiments that could push experimental limits on T-violating BSM physics to the PeV scale
