Dark matter and dark energy may have driven inflation, the exponential expansion of the Universe moments after the Big Bang. A new cosmological model proposed by physicists at the University of Warsaw, which takes dark inflation into account, is the first to outline a precise chronology of the main events during the early history of our Universe. The model makes a spectacular prediction: that it should be possible to detect gravitational waves that were formed just fractions of a second after the creation of spacetime.
What do we know about the evolution of Universe immediately after the Big Bang? In spite of extensive research carried out over decades, current cosmological models still do not outline a precise chronology of events. Researchers at the Faculty of Physics at the University of Warsaw (UW Physics) have developed a new model in which the exponential expansion of dark matter and dark energy plays a key role. The dark inflation model organises the thermal history of the Universe in chronological order and predicts that we should soon be able to detect primordial gravitational waves formed immediately after the Big Bang.
