Point at infinity complex field, the set of points at infinity is a manifold. In artistic drawing and technical perspective, the projection on the picture plane of the point at infinity of a class of parallel lines is called their vanishing point. In hyperbolic geometry, points at infinity are typically named ideal points. Unlike Euclidean and elliptic geometries, each line has two points at infinity: given a line "l" and a point "P" not on "l", the right- and left-limiting parallels converge asymptotically to different points at infinity. All points at infinity together form the Cayley absolute or boundary of a hyperbolic plane.
The Parallel was sent out in. Gaines is summoned to examine the capsule, but when he approaches it he is gradually returned to the point at which he left his own universe. He lands his craft safely and reports what happened to his superiors. They are prepared to write it off as a nightmare, but controllers on the ground subsequently receive another transmission—from "Colonel" Robert Gaines. The transmission cuts out a few seconds later, and the Colonel disappears from radar. The Major returns home and happily confirms that his daughter now recognizes him and the white picket fence is absent. The Parallel
