Support the show with a tax-deductible donation of any amount so we can continue exploring the world's biggest questions without the need for paywalls.   When the long-awaited day dawns and the aliens finally arrive on Earth, they might eat us and destroy the planet―or, just maybe, they might share the secrets of the Universe with us. When that time comes, will we be able to cross the communication barrier to beg for our lives? If the aliens do hold out those precious jewels of knowledge, will we even be able to grasp them? Professor Daniel Whiteson and Warner explode what we thought we knew about talking to our cosmic neighbors―and even science itself―by asking and answering questions both lighthearted and profound.   Whiteson's book, Do Aliens Speak Physics?: And Other Questions about Science and the Nature of Reality, is available for purchase now.
