Science fiction films, television, books and short stories have been popular for decades and have, since their onset, relied on science and technology for their core concepts. With rocketing to the stars, time travel, planet busting weapons and sentient robots, it’s no wonder that they especially have relied on topics from physics and astronomy, and often from the cutting edge of these fields. Many fans have shown an interest in which concepts are possible (such as interstellar travel, time travel, teleportation or androids). In addition some fans have shown an interest in the basics, such as the background physics behind how a rocket works or how a star creates energy.
