Some light rays emitted from the Big Bang (BB) in Lemaitre - Tolman (L-T) and Szekeres (Sz) models reach all observers with an infinite blueshift. This happens when at the emission point the BB function t_B(r) has nonzero derivative and the ray propagates radially (in L-T) or along one of two preferred directions (in Sz). Consequently, some rays emitted during the last scattering period should...
