How will it all end? Predicting the far future of our Universe depends on understanding its present. This lecture starts with what seems to be a paradox in modern cosmology: that we have a model that does a fantastic job of explaining what we see, but which says 95% of the Universe is in forms (dark matter and dark energy) that we don’t understand. From there, we get a quick tour of the next 100 billion years – and speculate how the Universe’s end may hold the secrets of its beginnings. Featuring musician Steve Pretty.
