Conference : Is it possible to determine the age of time?
23 novembre 2019 17:30 - Amphi Gaston Berger

In most ancient traditions, there is an idea that the universe has not always existed. For them, there was a moment of creation which initiated the history of the world. For instance, in Genesis, God created the heavens and Earth, while in native cultures in Western Canada, the mythical crow takes on the role of the creator. Time becomes an interesting subject of inquiry if we combine this worldview with modern science. Our first question is the following: Is there evidence of a period when the universe did not exist and for which the act of creation represented its end? In other words: Has time always existed? Or rather: For how long has time existed?
