Can trees talk to each other? Can science help you commit the perfect murder? What might aliens look like and the burning question of our time, are strawberries alive or dead? Join them as each episode they put a different scientific topic under the microscope, from aliens, black holes and hedgehogs, to bacteria, poison and the Big Bang. With past guests including actors Dame Judi Dench and Sir Patrick Stewart, comedians Steve Martin and Conan O’Brien, astronaut Tim Peake, primatologist Jane Goodall and mathematician Hannah Fry, The Infinite Monkey Cage promises to make you laugh, enrich your knowledge and leave you with a deeper appreciation for the universe that we call home. Whether you’re a seasoned scientist or someone who nodded off in physics class, listen in to learn all about funny, fascinating and sometimes ridiculous topics – with the occasional monkey business.
