Wormholes, Exotic Matter, and the Intersection of Physics and Fiction

To the point

One cautious Caltech physicist grows curious about faster‑than‑light travel by examining wormholes, hypothetical tunnels in spacetime that could shortcut vast distances, while noting that enlarging and keeping them open would require exotic matter and is beyond today’s tech, and that such a path could lead to instant arrival or even time travel, a clear blend of hard physics and imaginative fiction that invites readers to see how science and story illuminate each other.
