摘要：The term “accelerating expansion” is contradicted to follow observation facts: Accelerating expansion means repulsive force account for 70% and the universal space will be open. However, the observation facts indicate that the cosmetic space is flat and cosmos microwave background radiation is blackbody radiation. That is to say, it is equilibrium radiation. The cosmos is a gravitationally bound system. Obviously, open space cannot form bound system. A lot of observation facts and the Hubble relation support that the cosmos is always in reduction expansion. The term is also contradicted to the warped and closed space demanded by cosmetic principle.
