In our latest Cosmic Queries episode, astrophysicist Neil deGrasse Tyson and comic co-host Leighann Lord answer your questions about exploration. From the depths of the ocean to the outer reaches of the galaxy and beyond, the two explore practical questions about the most efficient way for humans to get into space on a recurring basis (Space Elevator vs. chemical rocket), the likelihood of NASA using ion propulsion thrusters for travel within our solar system, and the feasibility of an interstellar probe to Alpha Centauri using existing technology. They also tackle theoretical questions, such as whether we’ll ever be capable of generating enough power to explore the higher dimensions, leading to a discussion of the book, Flatland.
