In this episode, we trace humanity's dream of mastering time — not through natural forces or cosmic tunnels, but through invention. Beginning with H.G. Wells's groundbreaking 1895 novel The Time Machine, the episode explores how fiction transformed time from an abstract concept into something mechanical and navigable. It then journeys through real-world theories, from Einstein's relativity to Gödel's time loops, Tipler's rotating cylinders, and Kip Thorne's wormhole models, all searching for the mechanism that might make time travel possible.

Yet the episode reveals that each attempt to engineer such a device leads to paradoxes and impossibilities. Physicists struggle with infinite energy demands, while storytellers use time machines to explore th ...
