Explain the three-dimensionality of the Universe

British, American, German, and Portuguese physicists have proposed a plausible explanation of the observed three-dimensional space (excluding time coordinate). A study accepted for publication in European Physical Journal C, available on the website arXiv.org briefly about it, reports Phys.org.

The hypothesis of scientists suggests that in the early stages of development of the Universe, about 13.8 billion years ago, a large part of the matter of the world was in a state of quark-gluon plasma. In the process of phase transition the quark-gluon plasma in the plasma there were protons and neutrons, forming nuclei of chemical elements.

The three-dimensionality of the Universe, the specialists explained that the nodes of the power tubes that bound the quarks and antiquark, sustainable only in three-dimensional space. A system of tubes that pervades the world with a higher number of spatial dimensions, could not exist for a long time.

In the standard models of particle physics and cosmology it is believed that in the early stages of development of the Universe there was a single strong and electroweak interaction, which at the inflation stage (period of exponential expansion), there was a selection of the strong interaction.

This process (baryogenesis) was accompanied by a unification of quarks and gluons into hadrons, as well as the likely emergence of cosmological topological defects (in particular, cosmological strings, walls and monopoles).
