Every age has characteristic inventions that change the world. In the
19th century it was the steam engine and the train. For the
20th, electric and gasoline power, aircraft, nuclear weapons,
even ventures into space. Today, the planet is awash with electronic
business, chatter and virtual-reality entertainment so brilliant that
the division between real and simulated is hard to discern. But one new
idea from the 19th century has failed, so far, to enter
reality--time travel, using machines to turn the time dimension into a
two-way highway. Will it come true, as foreseen in science fiction?
Might we expect visits to and from the future, sooner than from space?
That is the Time Machine Hypothesis, examined here by futurist Damien
Broderick, an award-winning writer and theorist of the genre of the
future. Broderick homes in on the topic through the lens of science as
well as fiction, exploring some fifty different time-travel scenarios
and conundrums found in the science fiction literature and film.
