Scientific paper

Fluctuations on de Sitter metric solution of Einstein-Cartan field equations are obtained in terms of the matter and spin-torsion density fluctuations. A proof for the gravitational instability of the de Sitter metric in spaces with torsion from COBE data is obtained. In fact Einstein-de Sitter solution is shown to be unstable even in the absence of torsion.
