topological defect

(defect in space that could arise in the early universe)

In cosmology, a topological defect is a discontinuity in space. Some theories expect the formation of such defects during the early universe's symmetry breaking that divided earlier, more general forces into the currently known specific forces of nature: gravity, electromagnetism, the strong force and the weak force. Such defects are classified as follows:

When the cosmic microwave background cold spot was identified, one theory was that it was a sign of a texture.
