On the Emergence of Lorentz Invariance and Unitarity from the Scattering Facet of Cosmological Polytopes
Nima Arkani-Hamed, Paolo Benincasa
The concepts of Lorentz invariance of local (flat space) physics, and unitarity of time evolution and the S-matrix, are famously rigid and robust, admitting no obvious consistent t…
