Science takes centre stage at HowTheLightGetsIn, the world’s largest philosophy and music festival, this May. Bringing together world-leading scientists, artists, philosophers and politicians including Roger Penrose, Laura Mersini-Houghton, Lawrence Krauss, John Ellis, Paul Krugman, Simon Baron-Cohen, George Ellis, John Searle, Tariq Ali and Lianne La Havas, for debates, talks and wild parties, this year’s programme examines the elements of reality that might soon turn out to be illusions.
