No air, No gravity

I noticed that some movie makers are confusing microgravity with vacuum. I have a scene in mind, where someone floats into an airlock from outer space, closes the door behind him and the air begins to hiss into the little room. Then somehow the gravity kicks in and the floating person falls immedieately to the hard ground. Last time I’ve seen this was yesterday in the movie “Sunshine”. Or perhaps they had some technology to turn gravity on and off?

I haven’t seen the movie yet (it’s not due out in North America until the end of the year, last I heard), but it would be interesting to see if that was deliberate or not.  Let’s give the movie-makers the benefit of the doubt and that the air lock can turn off its artificial gravity in the airlocks for EVAs. 🙂



  1. If I’m not mistaken Outland made this same mistake. While inside the mining complex, everyone seems to be in normal gravity, but when Sean Connery puts on a suit and goes outside, the gravity is suddenly lower. I could be mistaken since it’s been several years since I last saw this film, but I seem to recall him jumping off one of the structures and slowly falling down the side.

  2. The gravity generators run on air.:-p

  3. Hi,

    I don’t know if you’ve come across this reading but if you’re really interested in where our planet is on “Taming Gravity” you might want to read this Popular Mechanics Oct 1999 issue on Dr. Ning Li and her “A/C Gravity”.

    The article is titled “Taming Gravity” appropriately.

    The article does a very good job of explaining Dr. Ning Li’s A/C Gravity. It is a must read for anyone interested in where our planet is on the subject of “Taming Gravity”!

    If it’s real science then we have a break through. It’s certainly inspiring sense it’s by a main stream physicist.
