Neil deGrasse Tyson explains how plasma propulsion works, why long-distance space travel would involve accelerating halfway and decelerating the rest, and how Einstein’s equivalence principle links rockets and gravity. With examples from The Expanse and missteps in Ad Astra, he shows how physics reveals that acceleration itself can mimic gravity—letting astronauts live in “artificial gravity” without spinning ships.
