This thread is focused on how artificial gravity works in the STAR TREK Universe, most generally on Federation starships, but also on all other spacecraft including orbital and deep space stations, etc. I am specifically concerned about how it works in TOS, but we can talk about all of the TV series as well. One constant notable feature in STAR TREK, right from TOS forward, is that manned spacecraft invariably employ artificial gravitation technology of some sort for the benefit of the crew. This seems to allow the astronauts (of all species) to live in an environment that simulates/emulates natural life on a planet. (1: All Federation starships and shuttlecraft shown in TOS seem to employ artificial gravity to simulate something that must be Earth-normal 1g, at least by appearances. (2: Even damaged or otherwise disabled spacecraft seem to ultilize 1g-like gravitation of some sort, as even the adrift Botany Bay and Constellation, as well as the lifeless Exeter and Defiant, still seem to have working gravity. (3: Passage from one human-habitable space vessel to another doesn't seem to be a big deal for astronauts, so we can assume that even when Kirk caused the Astral Queen to dump the theater acting company and let the Enterprise take them aboard, the Players simply expected not to have to contend with any nasty environmental surprises. Ergo: the environmental conditions (gravity included) must be standardized. My question is this: If space-suited astronauts on the outer hull of a space vessel require "gravity boots" in order to walk about and not drift off into space, and yet non-suited personnel inside that hull generally take their pressurized, 1g internal environment almost for granted, how is this gravity produced with such reliability and fidelity? It wasn't until ENT's "In a Mirror, Darkly" that we see someone doing something unusual (not 1g) with the ship's environment. So, in-Universe, how is this supposedly done with no visible signs outside the ship? (Enterprise sat at the Romulan Neutral Zone in "Balance of Terror" with her power down, and yet her crew enjoyed seemingly Earth-normal conditions, only dimmed lights and non-functioning peripherals, and the only thing to alert the intruder-vessel was Spock's accidental signal.) So how is it (supposedly) done? I do not understand.
