In the S-matrix program of quantum field theory, a cosmohedron or cosmological polytope is a polytope used to computes the Wheeler-wavefunction of the universe in the theory. In this manner, cosmohedra are similar to the amplituhedra and associahedra, which are polytopes used to compute scattering amplitudes.
