Gravity

[-HP-]

Fuck it, just saw Gravity in 3d and this movie is MUST SEE in 3d. Great pictures, great tension, great soundtrack (if you can call it that way) anyway, great audio. I felt like i was up there in space for 90 min, great expirience !

When Rayan meet Mat in the chinese space station, he enters and she is literally in space for some time, i know it was just her dream, but is it posible to be in vacium without breathing and still be ok ?

 

 

Here's a link to your question, I was also very interested. I was questioning myself, what the feeling would be like.

Basically you would die from asphyxiation if you were there for too long. However, you can survive in space for a short period of time with very little effects. (30 seconds to 2 minutes if you can hold your breath for that long)

This is assuming you would go through slow depressurization methods like a pressure chamber, if not, I would assume sudden depressurization would severely harm your body, since space is a vacuum therefor there's no pressure?

I remember reading once about a deep sea scuba diver that ascended hundreds of meters in a couple mere seconds due to an accident with his O2 can, he went into a coma and his body needed years to recover, although I don't think he ever recovered in full, I wish I had the link to that article. Anyway, same principles apply, pressure/depressurize is very important, because space is a vacuum.

 

Apparently a space suit started leaking a few years ago ... before the guy lost consciousness he remembers the saliva in his mouth started to boil. That confirms what the article says about your body fluids starting to boil after a while.

My father is very passionate about everything related to space, NASA, mars missions etc. I think the last time he went to the movie theater was back in 1996 for Titanic haha. Last week, he asked me what the hell 3D movies meant.

After reading all your positive feedback from Gravity, I'm gonna surprise him and go watch Gravity in IMAX 3D with him

DO IT! And please, let us know the outcome!

good job.

Certainly you'd suffocate. Many humans have survived high vacuums. Your fluids would boil eventually, but likely after you're dead. Your heart and muscles would keep the fluids inside your body from boiling, as they'd keep the pressure up.. but fluids exposed to the vacuum would immediately boil (saliva, fluids in your lungs, etc), but while it'd be a strange sensation, it wouldn't hurt you.

If you were returned to atmosphere before you suffocated, decompression sickness would be the biggest concern.

I have a vacuum chamber at work, and I occasionally put a dish of water in there just to watch it boil. It's rather basic physics but it's so opposite of intuition that it still makes me grin stupidly.

On second thought, your fluids would probably only briefly boil after you died, since your body would rapidly cool.. some would likely boil, but for the most part remain trapped long enough to freeze.

this is some scary shit you guys

Just saw it, it was awesome! VERY impressed with the CG, it's one of the rare few times where everything felt really believable.

Didn't like George Clooney's preformance though, it was basically indistinguishable from Buzz Lightyear.

Also like all the little metaphors of birth, evolution etc =).

The pressure differences in space aren't as big as what scuba divers experience, so it wouldn't really cause that kind of decompression sickness. I think space suits even operate at only a third of athmospheric pressure . Also, you only get decompression sickness after prolonged exposure to a different pressure gradient, so if you recompress shortly after decompression you should be fine.

But yeah, you can survive in a vaccuum for up to two minutes I think, but you can only hold consciousness as long as oxygen is supplied to the brain, which is only something like 16 seconds.

There's a similar airlock scene in 2001 a space odyssey, which is supposed to be possible IRL:

What happens in the case of divers not respecting the proper decompression levels is the air in your lungs expands in your lungs faster than the lungs themselves expand to their normal ATA (atmosphere pressure in open air at sea level). So in severe cases, you literally blow your lungs up (and you know, the veins and every other organ that contains fluids that also get compressed by water pressure.

 

That's why you're always supposed to let air out of your nose or mouth as you get back to the surface, even when scuba diving. 1 ATA = roughly 15 psi (air has weight, therefore applies pressure, of about 15 pounds per square inch (psi) at sea level, and every 33 feet (11 meters) of salt water adds 1 ATA to the amount of pressure a diver feels.

 

Anyway, went to see Gravity tonight in IMAX 3D and two thoughts immediately came to mind:

 

 - No one should ever attempt to make a survival movie again, as Gravity just mastered every single aspect of it.

 - For the very first time ever, I felt that 3D made the movie better as opposed to being just a gimmick in all other movies. And that's a huge accomplishment

yup the 3D thing literally comes from the fact you have a perfect foreground, mid and background framed due to the extreme distances involved, perfect for the tech. last movie that gave me any good impression of 3D was Avatar, although not on the same scale as Gravity, they did similar things.

Finally got to see it, absolutely incredible~~and I actually really liked the 3D. Fucking intense shit, left me breathless for many long segments of the movie, almost felt like you were there

 

It totally lost me for just a few seconds when Kowalski got into the capsule, and then just a moment before the camera panned back then it hit me that obviously she was hallucinating because she was running out of oxygen.

 

So good, gotta watch it again soon!~

[2d-chris]

yeah right, he's the most humble dude ever, still a funny article though

A super-invasive ad that was playing a video IN THE BACKGROUND graphics of a website (IGN I think) reminded me a few days ago the movie was coming out thursday in UK.

I'm trying to organize to go and see it in an IMAX theatre. My in-law seems to be willing to back me up, thanks to the hype this movie has: "If you want to see the best movie Hollywood put out, you really want to see it on the biggest screen in Britain" (trying to convince my sister to go to Waterloo's IMAX).

[PogoP]

Yep this is out in the UK now. Gonna go see it this afternoon!

[PogoP]

Fuck that was amazing.

[Taylor Swift]

i need to see this in 3d
