  In the SU(2)_L x U(1)_Y standard electroweak theory coupled with the Einstein
gravity, new topological configurations naturally emerge, if the spatial
section of the universe is globally a three-sphere (S^3) with a small radius.
The SU(2)_L gauge fields wrap the space nontrivially, producing homogeneous but
anisotropic space. As the universe expands, large electric and magnetic fields
are produced. The electromagnetic field configuration is characterized by the
Hopf map.
