Isso é The Space Eater de Dave Langford. O buraco de minhoca através do qual o herói é enviado tem cerca de dois centímetros de largura, então é uma sorte que eles tenham muito bons tanques de regeneração.
The Space Eater by David Langford was the author's first straight science fiction novel, making use of various alarming side effects of an imagined matter transmission technology, and featuring perhaps the most unpleasant means of interstellar travel in SF. There are also high-tech soldiers and a variety of boys' toys in the form of exotic weaponry, ranging from handguns to planet-wreckers.
