In this “This is World” episode, Professor Brian Cox guides viewers through today’s most pressing questions in physics and cosmology. He discusses the upcoming Mars Sample Return and Europa/Enceladus missions that could reveal microbial life within our own Solar System, then unpacks the black-hole information paradox—explaining how Hawking radiation may ultimately preserve everything that falls past the event horizon. Cox shows how scientists calculate the Universe’s 13.8-billion-year age, probes the true nature of time, and argues why intelligent civilizations might be exceptionally rare. Finally, he explores how quantum computers are already testing ideas at the frontier of gravity and spacetime theory, linking laboratory breakthroughs to the deepest mysteries of the cosmos.
