What makes you different from a rock? It feels like an easy, almost silly question. But scientists and philosophers still struggle to define where life truly begins and ends. And that leads to a deeper mystery: what is life, really? DNA is often called the code of life. But what does that really mean? Who, or what, is reading this code and why does life need a code in the first place?This video explores one of the deepest mysteries in science and philosophy: how molecules become messages. From the genetic code inside your cells to the scent of pine needles in the forest, life is filled with signs and symbols that carry meaning. Some scientists argue that DNA is just chemistry. Others suggest it’s something more radical, a system of interpretation, where meaning itself may have come before matter.In this episode we'll discuss:
At the heart of it lies a profound question: is life made of molecules, or of meaning? And if meaning is the foundation of life, how should we think about the future of evolution, technology, and our search for life beyond Earth?
