-We say that the value of omega (exact) should be of 1,023 +- 0,02, which suggests that space with 3 dimensions is closed?
-the metric fluctuates in the infinitely small, then why its principal characteristic,its signature, should remain fixed?
-Is the mode ultracour of quantum gravity intrinssically topological so that the continius degrees of freedom desappear?
-Today, the speed of expansion of the universe rises with 72 km/s, and the value of the density of the universe is lower than the value of critical density. If the value of the universe exceeds the critical value, the expansion of the universe will be reversed completely and thus ended up this finding with the length of Planck? (big crunch)
