You've, technically, eaten food that was at zero gravity once for a short period of time.

- loceng 3y agoHehe. Thanks for that perspective.
- ceejayoz 3y agoFree-fall isn't zero-gravity, and anyone who observes the five-second rule has had a similar experience.

- colordrops 3y agoYes it is, didn't Einstein say that gravity and acceleration are indistinguishable
- someguyihope 3y ago"Zero-g" is different to "zero gravity". https://en.m.wikipedia.org/wiki/Weightlessness https://en.m.wikipedia.org/wiki/Weightlessness
- colordrops 3y agoThe whole microgravity thing is pedantic, yes tidal forces exist, but at human scales they are not detectable.
- ceejayoz 3y agoIn free-fall, the object is primarily being accelerated by gravity.
- colordrops 3y agoYes but this is indistinguishable from the perspective of the falling object.
- loceng 3y agoIf you're wanting to be so perfectionistic, five-second rule experiences is an apples to oranges comparison.
- mschuster91 3y agoRelatively to the aircraft, the food was zero gravity though?

- leoedin 3y agoBut by that argument neither is floating around in the ISS - you're still being accelerated by gravity, you're just in the fortunate position that you have enough velocity not to hit the earth. If the colloquial term "zero gravity" applies to someone in the ISS, then it also applies to someone in a suddenly dropping aircraft.
