Star Trek: The Motion Picture (1979)
A mysterious cloud as big as a moon begins destroying ships and planets across the galaxy. When the newly refitted U.S.S. Enterprise heads out to investigate, it finds that the cloud contains an entire machine-based civilization. At its center is Voyager 6, an ancient American probe that had vanished into a black hole. The probe had exited another black hole, where it was found by the machines. They patched it up and allowed it to lead them to Earth.
Ain't happenin'. Nothing that enters a black hole comes back out again.
Many science fiction writers have used a theoretical construct called a wormhole as a shortcut between two widely separated locations in space. A wormhole would consist of two singularities, like the gravitational point at the center of a black hole. The theory says that if you step through one, you step out through the other, even though it might be many light-years away. The problem with using wormholes as a transport mechanism is that as soon as you (or any form of matter or energy) enters the wormhole, it collapses. So even if you could go in, you couldn't come back out.
