  1. The state of apparent weightlessness which occurs when in free fall.
  2. A state/shuttle/simulator which produces weightlessness.

I'm not sure exactly what sense 2 means, but is it not just listing examples of sense 1? Michael Z. 2011-12-14 00:12 z

1 is a state (situation); 2 is a machine.​—msh210 (talk) 00:32, 14 December 2011 (UTC)
Not getting it. Does shuttle mean “space shuttle?” I can't imagine how or when such a device is called “zero gravity.” Other dictionaries aren't helping me. Citation? Michael Z. 2011-12-14 03:54 z
You are getting it, then. (Well, if I am, then you are.) 2 is, yes, a space shuttle. Like you, I've never heard of this meaning of zero gravity; perhaps {{rfquote-sense}} or {{rfv-sense}}?​—msh210 (talk) 05:28, 14 December 2011 (UTC)
I'm quite certain that a space shuttle doesn't produce weightlessness. Having stared at this for a day, I believe it is nonsense. A bit of rewriting and rfv-sense, I think. Michael Z. 2011-12-14 15:10 z

It definitely produces weightlessness. Anyway, the sense 2 seems to be a nonsense. — TAKASUGI Shinji (talk) 18:00, 14 December 2011 (UTC)
Being in free fall, including being in orbit, leads to weightlessness, enshuttled or otherwise. A shuttle can be used to put you there, but to say that the machine “produces” the state implies some mechanism that doesn't exist. Michael Z. 2011-12-15 01:11 z
More precisely, being within any free-falling object produces a state equivalent to that of "weightlessness". However, "weightlessness" is a misnomer as the object does not actually lose all weight during its fall; objects simply are not resting against a static surface. "Weightlessness" can occur in a falling elevator, at the crest of a roller coaster, or inside a plane specially designed to free-fall with astronaut trainees inside. So, the second "definition" results from attributive use of the noun's primary definition and is not distinct. --EncycloPetey 03:28, 15 December 2011 (UTC)
