Event description

Modern physics is split in two. To explain the large-scale Universe, we talk of the curved and expanding spacetime of Einstein’s General Theory of Relativity. For the small-scale, we talk about probabilities and uncertainties and the language of quantum mechanics. Whilst these two pillars of physics are both supremely accurate and immensely powerful theories, they are, at heart, incompatible. But to understand the past, present and future history of the universe, we must get these two theories to play nicely together.

In this talk, Geraint Lewis will take you on a journey over eternity, exploring where and how the quantum and the cosmos have worked to shape the universe around us. He will also confront what we are yet to learn, from cosmic dawn to the ultimate twilight, in our quest to understand the Universe.
