Phasers, transporters, warp drive, replicators! Star Trek has given us glimpses of many technologies that may be or are close to happening in the real world. But there is one Trek Tech that is common for most science fiction and indeed the very thing we need to figure to make long term spaceflight viable: artificial gravity.
Star Trek uses synthetic gravity generators and grav-plating to provide simulated planetary gravity. These utilize graviton stabilizers that modulate the level of gravity produced, allowing gravity to be altered at will. Other science fiction – and many real world – designs for creating gravity on a spaceship feature rotating hulls. That simulate gravity on their interior surface using centripetal force and has to contend with the Coriolis force and its effects. Yet another popular science fiction source of gravity generation is through engine thrust using linear acceleration, where the ship’s engines that create the downward pull and if they are off, so is the gravity.
This question comes from our “Trek Technology and Science” category, where we often ask questions that bridge science fiction of Star Trek and real world science.
