Science Fiction

Science fiction movies often encourage audiences to dream up technologies beyond their wildest dreams, making them seem realistic enough to be plausible, only to be bitterly disappointed by the limitations of real-world science. The most ambitious science fiction movies have presented a wide variety of settings, from the spacefaring fantasy worlds of Star Wars to the grounded realism of films like Arrival. As a result, the cutting-edge inventions presented by these films run the gamut of plausibility, with many being closer to magic than science.

The laws of physics are a definitive roadblock in the path of developing many of the most famous science fiction devices in the real world. Try though they might to explain away reality-defying objects with undiscovered materials, rare elements, or fictional applications of real-world physics, some of the most exciting ideas from the genre are doomed to never make it past the ideation stage, operating on assumptions about the natural world that simply can't be replicated in reality. No matter the technology level humans are able to one day achieve, some sci-fi gadgets will sadly manifest in the real world.
