11 astounding sci-fi predictions that came true

Many literary forecasts of our technological future have already come to pass: the atomic bomb, the submarine, and even the iPad. Discovering passages of science fiction that turned out to be eerily accurate predictions is certainly quite entertaining.

It's also a point of controversy among science-fiction enthusiasts. Eric Rabkin, a professor at the University of Michigan and the 2010 winner of the Science Fiction Research Association's Pilgrim Award for lifetime achievement in science fiction scholarship, explains why.

"First, there's the infinite monkeys problem. If you have an infinite number of monkeys randomly pounding on typewriters for an infinite length of time, the odds are 100% that at least one of them will ... write Hamlet," explains Rabkin. "In other words, with thousands of [science fiction] writers turning out tens of thousands of visions of the future, in what sense is any coincidence between a future element and what comes to pass a prediction?"

Consider this a full disclosure: the following list is not exactly academic or even scientific. But the members of The Science Fiction Research Association who helped us compile this list agreed that these 11 science fiction prediction passages were entertaining enough to share.
