:The fundamental scientific issue is the lack of pressure in space. I actually doubt that the water would freeze, given the warmth it carries along with it. It will take some time to cool off, since the heat can only be lost through radiation. The pressure loss, however, is immediate, and much closer to absolute zero pressure than to absolute zero temperature. This means that rather than freeze, the water would vaporize -and even if it freezes, the crystals would either vaporize later, or would crystallize as microscopically tiny ice dust. It would be virtually impossible to capture this water with standard procedures, and what's worse, it would continue to expand during the time preparations are made. What you would essentially need is a bag of humongous proportions to capture all the water. Incidentally, it would maybe have been useful to store the water as some form of slush ice. This would make it practically impossible for someone to go a-swimming in the tanks and would make holes in the tanks less problematic. On the other hand, ice having a lower density than water, that would mean less actual water per tank volume. --[[User:OliverH.|OliverH.]] 08:27, 17 February 2006 (EST) | |||

The Lost Water
I realize from the blog entries that this episode was rather hacked up, but I was wondering; why is there never an attempt to recover the water Galactica blew overboard? The external shot of the tank rupturing beautifully shows the water blasting out of the tanking and freezing almost instantly as it hits the void, but there's never any discussion of going out there with a cargo net and recovering the ice, which certainly couldn't have made it very far in the timeframe the episode takes place in. Was there ever a stated reason this tactic wasn't employeed, or is there some fundamental scientific issue I'm not seeing with trying to recover the escaped water?
- The fundamental scientific issue is the lack of pressure in space. I actually doubt that the water would freeze, given the warmth it carries along with it. It will take some time to cool off, since the heat can only be lost through radiation. The pressure loss, however, is immediate, and much closer to absolute zero pressure than to absolute zero temperature. This means that rather than freeze, the water would vaporize -and even if it freezes, the crystals would either vaporize later, or would crystallize as microscopically tiny ice dust. It would be virtually impossible to capture this water with standard procedures, and what's worse, it would continue to expand during the time preparations are made. What you would essentially need is a bag of humongous proportions to capture all the water. Incidentally, it would maybe have been useful to store the water as some form of slush ice. This would make it practically impossible for someone to go a-swimming in the tanks and would make holes in the tanks less problematic. On the other hand, ice having a lower density than water, that would mean less actual water per tank volume. --OliverH. 08:27, 17 February 2006 (EST)
Different Screen Capture Needed?
The current pic is portrait, which stretches out the Episode Data template pretty far down (which is why the template suggests the use of landscape oriented shots). Does anybody have (or have the means to take) a good landscape oriented shot for this episode? --Steelviper 16:49, 9 January 2006 (EST)
- I agree. If anyone has a Season 1 DVD available, step up to the plate with a good 4:3 or 16:9 proportion screencap for this and any other S1 episode page with odd screen caps like the one that appears here. --Spencerian 16:52, 9 January 2006 (EST)
