Predicting the conditions of the early universe is straightforward as long as we know how matter and energy behave under such extreme conditions. Although it may sound strange to talk about the universe during its first fraction of a second our ideas about the. The early universe was filled with radiation and elementary particles, it was so hot and dense that the energy of radiation could turn particles of matter and antimatter which then collided and turned back into radiation. History of the universe according to the big bang theory: Observing radiation left over from the big bang: Abundances of elements supporting the big bang theory: Models of inflation make specific predictions about the temperature patterns we should observe in the cosmic microwave background, the observed patterns seen in recent observations by microwave telescopes match those predicted by inflation. Darkness of the night sky as evidence for the big bang:
