Abstract
The Cosmic Defect (CD) theory describes the accelerated expansion of the universe in terms of a four‐dimensional defect in the texture of space‐time, similar to defects in crystals and material continua, and of its influence on the metric properties of the medium. What we, in our 3+1 view, interpret as a non‐uniform expansion rate, appears in this theory as a strained state of space‐time. Adding matter to the strained space‐time the theory accounts for an initial inflationary era, followed by a sequence of decelerated‐accelerated‐decelerated expansion; the expansion asymptotically ends at time infinity. The theoretical predictions of CD are contrasted with observational data from type Ia Supernovae, and compared with the predictions of the Λ‐cold‐dark‐matter theory (ΛCDM). The result is positive, showing a good correspondence with the data at a level comparable with the one for ΛCDM. Further implications and the correspondence with other pieces of evidence are discussed.
