# The Quantum Origin of the Universe

In this new talk from SETI, Prof James Hartle from the University of California, Santa Barbara, will talk about his work on the marriage of quantum physics and gravity. If the universe can be described by a wave function, that is if it obeys the laws of quantum mechanics, this function can specify how the universe started at the big bang. If such a wave function does exist, it has very interesting properties — it provides quantum probabilities for all events and is an essential part in the “theory of everything”. Prof Hartle will discuss his work and the frontiers in the theoretical physics of quantum gravity. As always, for more videos check out the links below.
