| - Inertial Dampening (or "Damping", if you prefer your inertia dry) is a piece of Applied Phlebotinum, designed to allow humans to accelerate and decelerate at high rates without becoming humorously colored paste on the walls. Its intention is to "take away" inertial effects; i.e., when accelerating, you are not pressed back into your seat (or liquefied and wedged into your seat.) For the most part, it's an invisible seatbelt substitute for crew and cargo. Sometimes Inertial Dampening has a "lag", where a sharp turn or quick deceleration will momentarily cause a reaction (quick fall into the console or press back due to high accelerations). Inertial Dampening is generally not Tim Taylor Technology. An overloading IDF [Inertial Dampening Field] has the opposite effect of most Applied Phlebotinum, causing a greater inertial effect, usually culminating in a Star Trek Shake. Generally, however, the Star Trek Shake has no relation to the direction of inertia; i.e., the ship is traveling forward, but the crew feels a right-to-left effect. Though often left unmentioned, Inertial Dampening is a requisite side-technology to any spaceship that can turn or accelerate faster than an ocean liner. It's the reason why The Bridge has No Seat Belts. Note that the physical Hand Wave that accompanies many forms of Faster-Than-Light Travel dictate that the ship does not accelerate in the traditional Newtonian or, for that matter, Einsteinian fashion, and so the inertial dampener is mostly for maneuvering and orbit changes. In hard Sci Fi, especially written but occasionally not, a more realistic method is used to cushion acceleration shock. Immersion in a fluid equal in density to the body would theoretically cause buoyancy forces to act counter to any accelerations; this is sometimes coupled with cryonics. Some method to allow the subject to continue to breathe in the fluid would be required, be it oxygenated liquids or a circulatory gas-exchange system. Since people riding around in bathtubs are not interesting on-screen (except from a voyeur's point-of-view) this has only rarely trickled down to the big and small screens; the exploration ship in Event Horizon and presumably the cryonics pods in the Alien series are the exceptions. Another relatively hard way would be use of dynamical Artificial Gravity to compensate inertial forces. See also Artificial Gravity. Examples of Inertial Dampening include:
