By Matt Visser

From H.G. Wells to megastar Trek, audiences were captivated via the notions of time go back and forth, time warps, area warps, and wornholes. yet technological know-how fiction isn't the simply realm the place those ideas thrive. An lively team of common relativists and quantum box theorists has produced a substantial physique of significant (thought admittedly speculative) mathematical and actual analyses of the wormhole procedure. Now, with this attention-grabbing publication, readers can discover intensive the technology in the back of the technology fiction. Drawing on pivotal paintings via Einstein, Wheeler, Morris, Thorne, Hawking, and others, Matt Visser charts the improvement and present nation of Lorentzian wormhole physics. Dr. Visser indicates that through pushing tested actual theories to their limits, it really is attainable to infer the actual homes of such exotica as wormholes and time go back and forth. The actual framework he makes use of is derived from one of many significant learn frontiers of recent theoretical physics: quantum gravity-the intersection of classical Einstein gravity and quantum box conception. Physicists, scholars of basic relativity, cosmology, quantum physics, or any reader with a heritage in physics wil locate this a provocative advent to a thrilling and energetic subject of ongoing study.
