Galactica 2.2

Sci-Fi just announced Battlestar Galactica has been picked up for a second season. In spite of some glaring plot holes (water blowing out into space means it's lost forever, sealing a hole in the hull of a fighter with a flight jacket, etc.) I still think it's probably the best new SF show on TV right now. I like it about as much as I liked Farscape (which is to say, a lot), but for different reasons. So if you haven't seen it yet, give it a shot!

Update: Ron Moore's "Blog" provides more insight into the series and where it's going after the renewal announcement.

How are either of those plot holes? Yes, if water explodes out into space, it's gone forever. How are you supposed to get it back? It's gonna spread out in basically all directions at many feet per second.

And what you call a flight jacket was actually Starbuck's pressure suit. Which is, you know, designed to be airtight and stuff.

* The water didn't actually spill and disappear, it just ejected and flash-froze. While I understand a "search for water" episode was much more dramatic than a "how do we shovel the snow back in" one (which is why I still enjoyed the episode), it would've been nice to have a few throwaway lines explaining "why we can't going back out and get it".

* Patching a hole in a deck is one thing... you just have to make sure nothing falls through. Patching a hole in a pressurized system, especially one with the differentials involved in manned space travel, is completely different and much more difficult. Yes, the suit was airtight, but from what I saw it was not secured in any way, which should have meant it oozing out the hole at about 25,000 feet ASL. Again, it would've been nice to have just a few muttered lines of dialog and one three second cut scene detailing how she secured the thing to make me happy, but I dealt with it and still enjoyed the show.

Which I guess is why I loved Farscape so much. They always dealt with the details, usually in a humorous way that advanced the plot, and they never backed down from the inconvenient complications that such details might cause.

Again, I like the show, I actually like it quite a lot. I think the characters are very interesting, the art and camera direction original, and the stories surprising and unpredictable. This is what makes Galactica a "very good" show IMO.

It's just, again IMO, if they dealt with the details better it would be a great show.

Um. Water in a vacuum doesn't freeze. It boils. It expands explosively as oxygen and other gases that are dissolved in it are released. It wouldn't have been snow as much as a very, very thin mist. And within an hour, it would have been spread out over a volume of Earth's moon.

And the pressure differentials involved in space travel are only three or four pounds per square inch, all outward. Meaning the pressure suit would have been pressed more tightly against the puncture in space than it was on the surface, and it was wedged in there just fine on the surface. Remember, leaks are fine as long as you maintain positive pressure on the inside.

At zero pressure it boils, yes, but at zero pressure and ~ -270C? Actually, it turns into an interesting physics puzzle... just what would happen to millions of gallons of liquid water suddenly introduced to an interstellar environment? I can't find anything on the internet to tell me.

The pressure difference at 15,000 feet versus vacuum is actually seven PSI, which (assuming that hole was 8" across) would amount to about three hundred fifty pounds of pressure trying to squirt that flight suit through that hole. I think something held in with simple friction would depart with a "bang" at high altitude, let alone hard vacuum. You can, do, disagree. That's the glory of SF! :)

These were the problems I spotted, and I'm just a dumb redneck from Arkansas. They didn't break my suspension of disbelief, but they rattled it pretty hard. I was disappointed because it seems to me so easy to address... a line of dialog about aerosol here, a single shot of that raider trying to "heal" over the hole there, and I'm happy.

To me, one of the best parts of sci-fi is its attention to such detail. I learn about real things and have fun predicting fictional ones when I read SF because they have the time and space to deal with all these little details. Sometimes it's real physics (millions of gallons of water vs. hyper freezing temps & zero pressure = ?), sometimes it's fiction from whole cloth (how does a semi-organic spacecraft fix itself?) but it's always given at least a little bit of print.

I think Galactica would be so much better if they spent just a little time doing the same thing.

Since my cell phone is limiting me to under 200 characters, let me point out that water is naturally solid at zero pressure and 3 degrees Kelvin, otherwise comets wouldn't exist.
