RE: Fire in microgravity.
Obnoxious delivery style, but the basic facts are there and a few good visuals: https://www.youtube.com/watch?v=9zdD7lfB0Fs Or for a much more in-depth look at fire safety in space than you ever thought you could find on Youtube: https://www.youtube.com/watch?v=wSMdW4z1P78 (Martin Shipp talks of BRE (FRS) work to study fires in microgravity and the review of the fire safety strategy for the Columbus Module of the International Space Station. 48 minutes long) |

Too bad the writers didn't try harder on the worst episode of the original Battlestar Galactica "Fire in Space".

I used my vacuum cleaner today. It caused all the air in my living room to blow dirt from my carpet neatly into the vacuum cleaner's nozzle.

When you drink lemonade, you say that you sucked it through straw instead of "the atmospheric pressure pressing on the surface of the cup squirted the lemonade to your mouth". While drinking, an overhead ventilator might be blowing air on you. How is this blowing related to the people being blown out of the aircraft? By the way, watch mythbusters as they tried to pressurize an aircraft and shoot through the window to have stuff / people blown / sucked out of the aircraft ;-) *Much* less spectacular result than movies might led you to believe.

Exactly. It takes a BIG hole to cause a blowout. A small hole, like a nail in a tyre,, causes a slow flat. Arthur C Clarke knew this back in 1953, when he wrote The Sands of Mars. The ship is hit by a micrometeorite; the result is a slow pressure drop, not a blowout.
Mind you, if the shot went through a plastic aircraft window which cracked wide open, yes, a catastrophic blowout could occur. But not necessarily. I recall Oddjob being shot out of a window like a champagne cork in Goldfinger (the book as well as the film) and I thing Fleming said "sucked" in the book... Why do I remember these things? It's a worry. |

I saw that Mythbusters episode when it was first on. I knew before seeing it that the scene in "US Marshals" was complete bolshoi. Holes in the windows or skin are at worst an inconvenience which requires a quick descent and abort to the nearest airport. Blowing out a whole window literally requires a decent sized explosive and small to medium sized people could get blown out - but only if they're close as the pressure drops very fast.
That's another problem with so many books and shows, the decompression is drawn out far too long. A decent size hole will equalize pressure in a large plane in a short time. On space ships or stations, unless it's a really large space like a hangar or construction room, same thing as doors would be closed to limit air loss. |

I guess that for me, I can be pretty much fooled by a good writer. My science isn't strong, so convincing settings and events will usually keep me involved. For some reason I find this less so in movies - I can accept any sort of premise to a point - but it often amuses me when I get to the 'that would never happen' moment when all the acceptances I've already made become unstitched.

This conversation reminds me of Alien Resurrection, which I recall had a newborn alien sucked/blown out of a bullet hole in the side of a spaceship. Of course, the science was the least of that movies problems.

But in BSG, they had artificial gravity on the ships so fire would behave the same as it does on Earth - it wasn't in a microgravity environment at least wherever the magic ship's gravity was present.

There's an awful lot of books and movies (most?) that called "science fiction" that aren't - they're fantasy with technical looking gizmos. Sometimes they might tip their hat gently is the direction of realism, but it isn't a priority. As a fantasy fan, I'm okay with that.
If you want science then get it from somewhere reliable - somewhere that isn't just trying to find what looks most impressive on the screen or sounds most exciting on the page. But if you want entertainment, then boost your credulity for a while and have fun. |

Ah, Mythbusters. The show that wants you to believe that if two mid-budget special effects guys can't do it in the time it takes to make a cable TV episode, then NO ONE CAN!!! Bwahaha! Quote:
Internal continuity comes next, else you get taken out of the story and can't suspend disbelief. Actual factual technical accuracy needs to come below those things in terms of priority, but as a science and SF buff, I do enjoy it, and I'd seek out writers who manage it. As for the OP, I agree with most of the respondents: Suck is just as correct as blow depending on your point of view. I found it unworthy of Commander Data to correct Riker on the same matter on that one episode of ST:TNG, as well: But, what can we do. After all, most writers are writers, not scientists, or space cowboys. ApK Last edited by ApK; 08-11-2014 at 11:40 AM. |
