Greene argues that space and time are not a stage set, but an elastic fabric whose weave changes with matter, motion, and information.

He journeys through paradoxes and head-scratchers that change the way we think about the natural universe - such as that clocks tick at different rates and “now” depends on how you move. He walks you into quantum strangeness where particles separated by galaxies can share a single fate. He shows how entropy gives time its arrow, links cosmic expansion to the Big Bang’s initial conditions, and asks whether the universe is a hologram with depth encoded on a distant boundary. And as a possible unifier, he tours string theory’s tiny vibrating filaments and their hidden dimensions, while admitting what we don’t yet know.

The payoff is practical curiosity: you come away seeing GPS, black holes, and even memory through new eyes—and sensing why cracking this fabric could change our story of reality.
