Can Interstellar Travel Be Possible?
Summary
This episode explores whether the Fermi Paradox is explained by the sheer difficulty of interstellar travel. The host analyzes the challenges of reaching relativistic speeds and surviving the interstellar medium, noting that while micrometeoroids and radiation pose significant threats, they are not insurmountable. By designing a plausible mission to Proxima Centauri, the show concludes that interstellar travel is difficult but not impossible, suggesting the universe is not hostile enough to prevent expansion. The segment also briefly addresses listener questions on quantum mechanics and bla…
