373: Space Rocks, Star Stuff, and Tom Selleck's Mustache with Greg Brennecka
“So I guess the way I see it is that, no, life on Earth probably wouldn’t be possible without meteorites, and that’s largely because of the ingredients that they delivered. They probably delivered the entire amount of our biosphere, in organic material, early in Earth’s history.”
More than a hundred million people watched the Netflix movie Don’t Look Up, which focused on our fear that something could crash into our planet from space and destroy it. But what if things that come from space don’t just have the potential to destroy life but also to create it? That’s Greg Brennecka’s argument, and he joins Indre on today’s episode to talk all about it. Greg is a staff scientist and cosmochemist at Lawrence Livermore National Laboratory, whose research has appeared in Science, Nature, and The Proceedings of the National Academy of Science (PNAS). He won the prestigious Sofja Kovalevskaja fellowship from the Alexander von Humboldt Foundation to study the early solar system and is a leader in understanding how things from space affect us down here on Earth. His new book is Impact: How Rocks from Space Led to Life, Culture, and Donkey Kong, and he discusses it and so much more (including Tom Selleck and his famous mustache) with Indre here today.
