The Unteleported Manby Philip K. Dick
Nobody would want to spend 18 years on a spaceship when you can make the journey via teleportation in an instant. In seconds, the Telpor effect could teleport you from an overcrowded Earth. 40 million emigrants had found it a solution to Earth's problems of pollution and overcrowding. But Rachmael ben Applebaum wasn't sure. Because there was a problem with the gateway to paradise. No one had ever returned.

Philip Kindred Dick (1928–1982) was an American novelist and short story writer whose published work during his lifetime was almost entirely in the science fiction genre. Dick explored sociological, political and metaphysical themes in novels dominated by monopolistic corporations, authoritarian governments, and altered states. In his later works, Dick's thematic focus strongly reflected his personal interest in metaphysics and theology. He often drew upon his own life experiences and addressed the nature of drug use, paranoia and schizophrenia, and transcendental experiences in novels such as A Scanner Darkly.
