Hidden Zeros of the Cosmological Wavefunction

Motivated by the recent discovery of hidden zeros in particle and string amplitudes, we characterize zeros of individual graphs contributing to the cosmological wavefunction. We construct polytopal realizations of the relevant graph associahedra and show that the cosmological zeros have natural geometric and physical interpretations as well as demonstrate that the wavefunction splits near these zeros. We also establish an equivalence between a family of flat-space wavefunction coefficients and $Tr[{\varphi }^3]$ amplitudes, consequently rediscovering their hidden zeros.
