What are they?Edit
What are antigravs? In the episode from Star Trek the Original Series entitled "The Changeling", Kirk finally says, "Scotty, some antigravs and meet me in engineering". Kirk heads to engineering to encounter Nomad, he reminds the probe that it is programmed to sterilize imperfections, and then points out its own imperfections. "Everything that is imperfect must be sterilized". Nomad becomes confused. Kirk cries out, "Now get those antigravs on him...while he is trying to think". They transport him out into space where he blows up.
- I found it difficult to understand why they would need such a device on something that was light enough to self-levitate. Nomad must have been quite massive and produced an "antigravitational field" in order to levitate, which was shut down as the unit was disabled. Mal7798 08:14, 10 January 2008 (UTC)
Yes--Spock indicates at the beginning of the episode that "the object" firing at the Enterprise has a mass of 500 kilograms (1100 pounds). That would make a real dent in the floor (and would be hard to drag down the corridor to the transporter room) if Nomad's anti-gravity field/beam thing were to shut down while it was "trying to think."--GSchnitzer 01:53, July 8, 2010 (UTC)
In "Obsession", a closeup of one of the units is shown where the name Anti-Grav is shown in what appears to be a trademark logo. I think this is evidence enough to canonically declare the term to be a trade name, and likely a genericized one, as Band-Aid and Jell-O have become. Mal7798 08:14, 10 January 2008 (UTC)
