The Big Bang has long been accepted as the ultimate origin of our universe – but what if it’s just the beginning of the story?
In this talk, astrophysicist Niayesh Afshordi will explore the fierce scientific debates over cosmic origins, revealing how modern cosmologists are rethinking the Big Bang itself. He will discuss the latest theories, including his own leading-edge research, that challenge the traditional narrative: was the Universe born from a black hole? Does time extend before the Big Bang? Could our cosmos be part of a vast multiverse or an eternal cycle of rebirth?
Science is not just about equations – it’s about people, rivalries, and radical ideas. Join Niayesh and colleague Phil Halper for a journey through the evolving frontiers of cosmology and the search for the true origins of our universe.
