The Way
The Way, a pipe-shaped universe 50 kilometers accross and of infinite length, the light provided by a linear flaw along its axis. Set in the walls of distorted space-time at intervals of a billion kilometers, gateways into other spaces.
The scientists and soldiers from Earth, stumbing into the Way, reconnoiter an inoperative gate
