Universe chaotic from very beginning | Science Blog: "The present-day universe is expanding and does so in all directions, Motter explained, leading to red shift of distant light sources in all three dimensions — the optical analog of the low pitch in a moving siren. The early universe, on the other hand, expanded in only two dimensions and contracted in the third dimension.
This led to red shift in two directions and blue shift in one. The contracting direction, however, was not always the same in this system. Instead, it alternated erratically between x, y and z.
“According to the classical theory of general relativity, the early universe experienced infinitely many oscillations between contracting and expanding directions,” Motter said."
