## Abstract

In this paper, we consider two almost opposite sectors of actual string configuration ansätze in AdS_{5}×S^{5}, which anyway have almost the same features: The two spin solution, which has constant angles in S^{5} and the two angular momenta solution, which has constant “angels” in AdS_{5}, however for the two angular momenta solution, we have to take the time coordinate from AdS_{5}, thus there is a little asymmetry between the two string configurations in AdS_{5}×S^{5}. Without being autistic, there is around 69 equations between the similar equations in the two sectors, compare equations (34) and (104) and also compare equations (64) and (134). Again, without being autistic, the text after the equations in the two sectors, is almost precisely the same. In our notation, the difference between the two sectors is as follows; ρ↔θ, ϕ↔ψ, sinhρ↔sinθ, y_{i}↔x_{i}, y↔x etc. The string configurations of this paper, are both solvable by the Neumann System. However, our setup in this paper is generally for the Neumann-Rosochatius System, which is also solvable, since we intend to generalize our results from the Neumann System to the Neumann-Rosochatius System and to several types of deformed Neumann-Rosochatius Systems. In the second part of this paper, which is independent of any string configurations in AdS_{5}×S^{5} and concerns String Cosmology in D=10 dimensions. I will seriously argue that there was no Big Bang; I truly believe that the Universe has been there forever, see True Conclusions, Section 10.^{2}
