Science writer and journalist Marcus Chown returns for a shorter, more philosophical chat. When Einstein first proposed gravitational waves, atoms hadn't even been discovered, so who knows what the next century holds? We dig into the strange idea of the universe's "mathematical twin," and discuss the Standard Model of physics - a brilliant framework, but riddled with holes. www.marcuschown.com
