Battle of the Big Bang: The New Tales of Our Cosmic Origins

Abstract

The story of the universe’s origins is one of the greatest mysteries in science. From the explosive birth of the cosmos to the enigmatic nature of time and space, we are continually challenged by paradoxes that defy current understanding. In this public talk, we shall explore the triumphs and debates that shape modern cosmology, and the novel quests to uncover our cosmic origins. I will also highlight the pioneering contributions of my friend and colleague, Lee Smolin. His groundbreaking ideas on quantum gravity, the nature of time, and cosmological evolution have sparked new directions in the search for a deeper theory of the universe. Together, we will journey through the frontiers of physics, exploring how new theories and astronomical observations might offer clues to the next great paradigm shift. Whether you’re a science enthusiast or just curious about the cosmos, join us for a conversation on the past, present, and future of our understanding of the universe.
