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 their formation during 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.
