Ekpyrotic Universe
The Ekpyrotic Universe is a cosmological model that suggests our universe was formed from the collision of two three-dimensional worlds, or "branes," in a higher-dimensional space. This theory contrasts with the traditional Big Bang model, proposing that the universe's expansion is a result of this collision rather than a singular explosive event.
In the Ekpyrotic scenario, the universe undergoes cycles of expansion and contraction, leading to a more stable and continuous existence. This model also addresses some issues in cosmology, such as the uniformity of the universe, by suggesting that the interactions between branes can create the observed large-scale structure of the cosmos.
