"The ekpyrotic (\u0115k\u2032p\u012B-r\u014Ft\u2032\u012Dk) universe, or ekpyrotic scenario, is a cosmological model of the early universe that explains the origin of the large-scale structure of the cosmos. The model has also been incorporated in the cyclic universe theory (or ekpyrotic cyclic universe theory), which proposes a complete cosmological history, both the past and future. The original ekpyrotic model was introduced by Justin Khoury, Burt Ovrut, Paul Steinhardt and Neil Turok in 2001."@en .
