It is possible to guess long. I remember, how studying on the Moscow State University specially studied all course of theories which on an output state the accelerated extension of the Universe, presence of dark energies and matters, a row of other things. As a result now I do not trust generally to the modern cosmology. It is a lot of assumptions at each stage, it is a lot of assumptions (Russell's teapot is entered at each opportunity), autumn a lot of courageous extrapolation of local theories on universal scale. Can ask any who seriously is engaged in cosmology "the modern representation is the fact, or all the same assumptions?" . And he answers that it "assumptions, but the best that now is". Also it is necessary not to forget that in cosmology now there are no typical scenarios of check of theories. The typical circuit is when the consequence is deduced from the theory, it is checked and proves to be true. Thus, for example, confirmed FROM in scales of star systems. And further already converges nothing. Therefore adjust the theory that it coincided with observations. Look more deeply/further - again do not coincide. It is necessary to adjust again the theory, to enter Russell's teapots that all converged. Usefulness of such theories - 0. They do not give the new information. The favor would be, if from the new theory there would be consequences which could be used. Alas - it is not present. It is all it doesn't matter. Now the cosmology goes by the way of information accumulation (experiments, their results). When the critical amount of crude results the new theory not containing teapots of Russell and giving answers to questions which we cannot watch yet will be possibly born collects.
