From May 17, 2023. In this episode, we discuss one mass extinction, three stories with volcanoes, star formation, galaxy dissolution, and space mission synchronized observing. We also take a closer look at dark energy and dark matter and how giant galaxies in the early universe seem to indicate we may know even less than we thought. And rockets. There are always more rockets thanks to SpaceX.
