Completeness from Gravitational Scattering
Francesco Calisto, Clifford Cheung, Grant N. Remmen +2
We prove that symmetry in the presence of gravity implies a version of the completeness hypothesis. For a broad class of theories, we demonstrate that the existence of finitely man…
Strings from Almost Nothing
Clifford Cheung, Grant N. Remmen, Francesco Sciotti +1
We argue that string theory emerges inevitably from a few simple assumptions about physical scattering. Consistency alone requires that all tree-level four-point scattering amplitu…
Multipositivity Bounds for Scattering Amplitudes
Clifford Cheung, Grant N. Remmen
Lorentz invariance, unitarity, and causality enforce powerful constraints on the theory space of physical scattering amplitudes. However, virtually all efforts in this direction ha…
Black Hole Complementarity and ER/EPR
Ning Bao, Grant N. Remmen
We demonstrate that wormholes must be entangled regardless of asymptotic boundary conditions. Assuming black hole complementarity, we argue that traversable wormholes instantiate e…
