    The Rocket Engines That Don't Burn Fuel | Dr. Naia Butler-Craig

    In this episode of Curiosity Theory, hosts Dr. Dakotah Tyler and Justin Shaifer sit down with Dr. Naia Butler-Craig, a newly minted aerospace engineer and NASA electric propulsion researcher, for a conversation about rocket science, how we actually move through space, and where humans are headed next. The discussion moves from her path through grad school and into NASA to how electric propulsion works and why it beats chemical rockets on efficiency, what it would really take to get people to the Moon and Mars, and what living and working at the agency is like from the inside. Along the way, she breaks down what is happening inside a Krypton Hall effect thruster and why plasma, not combustion, is the future of deep space travel. The conversation also dives into why astrology is not astronomy, how to think about trust and misinformation in science, the engineering and people behind the missions we take for granted, and the surprising ways space tech is advancing medicine on Earth through Avatar tissue chips. It closes on the sci-fi and the curious childhood that set her on this path in the first place.

    What Dark Matter Actually Is | KeShawn Ivory (dark.mattering)

    In this episode of Curiosity Theory, hosts Dr. Dakotah Tyler and Justin Shaifer sit down with KeShawn Ivory, a soon-to-be PhD astrophysicist who studies the large-scale structure of the universe, for a deep conversation about dark matter, cosmology, and the invisible stuff that holds the universe together. The discussion moves from what dark matter actually is to how the universe became clumpy and lumpy instead of smooth, why the first atoms appeared minutes after the Big Bang, and how primordial black holes (a mountain's worth of mass packed into the size of a proton) became one of the more compelling candidates for what dark matter might be. Along the way, they get into how scientists detect something they can't see, what counts as evidence, and how scientific consensus actually moves. The conversation also dives into the hunt for dark matter through detection experiments, the role of skepticism in good science, what it means to know something, and KeShawn's favorite idea of all: that dark matter works as a framework for any force that is deeply impactful but hard to see, from race and systemic disparities in sociology to genomic dark matter in biology and trauma in art.
