In this episode of The Interplanetary Podcast, I'm joined by ay new co-host, singer-songwriter Leddra Chapman, as we tackle one of the most mind-bending ideas in all of science: special relativity. From the speed of light and the nature of causality to time dilation, the ether, and Einstein's revolutionary insight into space and time, we follow the story that changed our understanding of reality. And, as always, I can't resist ending with a slightly outrageous thought experiment of my own.
Former NASA food scientist Ryan Dowdy PhD joins Matt to explore how Artemis program is reshaping the future of human nutrition, from feeding astronauts on the ISS to the Moon and beyond to powering first responders here on Earth.
