NASA: the universe is finite and small

The data obtained by NASA spacecraft have baffled astronomers with a new urgency and raised the question of the possible limitations of the universe. There is evidence that it is also surprisingly low (in astronomical, of course, scale), and only because of the kind of "optical illusion of view," it seems to us that it is no end in sight.
Confusion in the scientific community have caused data from the U.S. probe WMAP (Wilkinson Microwave Anisotropy Probe), operating since 2001. His instrument measured the temperature fluctuations of the microwave radiation. Astronomers, in particular, interested in the distribution of values ("size") fluctuations, as it can shed light on the processes taking place in the universe at the initial stages of its development. So, if the universe were infinite, the range of these fluctuations would be unlimited. The analysis of the WMAP data on small-scale fluctuations in the CMB support the hypothesis of an infinite universe. However, it turned out that the large-scale fluctuations in virtually disappear.
Computer simulation confirmed that the distribution of such fluctuations arises only in the case if small size of the universe, and they can not simply be extended over the field fluctuations. According to scientists, these results show not only the unexpectedly small size of the universe, but also the fact that the space in it "closed in on itself." Despite its limitations, such as the edge of the universe does not have — a beam of light propagating through space, has a certain (large) amount of time to return to the starting point. Because of this effect, for example, the Earth, astronomers can observe the same galaxy in different parts of the sky (and even from different angles). We can say that the universe — is mirrored room in which every object is inside, gives a lot of their mirror images.
According to the simulation, the results of WMAP observations suggest that the universe is a set of infinitely repeating dodecahedron — regular polyhedra, the surface of which is formed by 12 regular pentagons. It is this shape is familiar to all footballs. At the same time, according to astronomers, the similarities between "dodekaedrovoy" model of the universe and the WMAP data simply "awesome" and they "fit together much better than one could imagine."
If the results are confirmed, our view of the universe will need a serious correction. First, it would be relatively small — about 70 billion light-years across. Secondly, it becomes possible to observe the universe whole and make sure that there are always the same physical laws.
