We investigate the flat space time Friedmann Lemaitre Robertson Walker model of cosmology in the light of two metric signatures:(-,+,+,+) and (+,-,-,-). We arrive at the interesting fact that with the (+,-,-,-)signature both the Ricci scalar and the energy component of the stress energy tensor are negative for all points of cosmological time. With this component we do have a positive pressure favoring the expansion of the universe.
