Nonrelativistic spacetimes with cosmological constant
Abstract
Recent data on supernovae favour high values of the cosmological constant. Spacetimes with a cosmological constant have nonrelativistic kinematics quite different from Galilean kinematics. de Sitter spacetimes, vacuum solutions of Einstein's equations with a cosmological constant, reduce in the nonrelativistic limit to NewtonHooke spacetimes, which are nonmetric homogeneous spacetimes with nonvanishing curvature. The whole nonrelativistic kinematics would then be modified, with possible consequences to cosmology, and in particular to the missingmass problem.
