© 2020 American Physical Society. We measure inelastic collisions between ultracold CaF molecules by combining two optical tweezers, each containing a single molecule. We observe collisions between, and in excited hyperfine and rotational states. In the absolute ground state, we find a two-body loss rate of, which is below, but close to, the predicted universal loss rate
