Funnily enough a few days after I watched Gravity I was at Airbus chatting to some guys who get paid to worry about this sort of thing for a living, and they said more or less that (ignoring the geostationary stuff, just focus on the LEO stuff) a debris cascade as portrayed isn't beyond the realms of possibility.

Everything sent up to space has to be as light as possible, so it's only as strong as it absolutely has to be. You also forget the truly outrageous speeds up there, that makes the forces in the collisions terrifying. I think the debris flies a LOT faster than a bullet, and usually has much more mass on top of it.
As for why the guy keeps the dogs near the radio, he's an eskimo sitting outside in the snow.

):Yes yes, things move fast in orbit around the earth. However a small piece of debris slams into your space station at 40kph it's not going to tear the entire station to pieces, it'll make a small hole going in and a somewhat bigger hole coming out. If there's an atmosphere inside the shockwave will rupture the hull and make a bigger still hole, sure, but the entire thing isn't going to suddenly start spinning like a top and get ground up like you put the whole structure in a blender. Now, if the projectiles moved at relativistic speed, Interesting Things Would Happen, but that's not really the case here now is it?
Also, how does that debris stay in the same orbit for at least 3 laps when it moves way, way FASTER than the other stuff in the same orbit? It should reasonably race past ONCE at most if it has to pass by at all right at that particular spot (space is big so what's the probability of that happening even once) on its way upwards and then not come back again for months or possibly even years until their individual orbits decay.

Point is that stuff in LEO is moving at 7km/sec, not 40kph.
Each spacecraft has its own orbital plane, many are low inclination ~28deg some higher ~52deg, others are near polar. It depends on where they're launched from and what their purpose is. Earth observation platforms and spy sats tend to be in polar orbits because they can cover the whole planet as it rotates underneath them. Those that look outwards is less constrained (eg. HST) but might want to avoid the hostile environments such as the South Atlantic Anamoly.
If you frag a sat that's in a polar orbit it basically turns into a blender that'll frag anything an quasi-equatorial orbit at a similar altitude. Which in turn will turn into a debris cloud that'll frag the next thing in a polar orbit that happens to be in the wrong place at the wrong time. It doesn't take too many of these interactions to make LEO a seriously bad place to be.

You really, really need a shag. You'll feel so relaxed afterwards.
In the movie it could happen, and that is the premise for most movies. IMHO you can complain about anything just not that

Honestly, of all the sci-fi or sci-fact movies, Gravity certainly is not the one that springs to mind when thinking about offensively stupid films. Maybe it does take some liberties here and there, but for the average movie goer without a degree in astro physics, it's perfectly fine. Realistically you couldn't even lift your arms over your shoulders in a Nasa suit, and you certainly couldn't suit up in a matter of minutes all by yourself either. But hey, it's a movie. It dramatizes certain things. That's what films do. And what the hell's the issue with having a dude with a crying baby and a barking dog on the radio? That's not a particularly special scenario. Maybe it deserves criticism for - once again - hammering home the point that
. Logically I see nothing wrong with it, though. I thought it was a very bitter-sweet moment myself.
I fucking love that movie.

I fucking love that movie.
Caught American Hustle at a 2nd run $3 theater last weekend and loved it. I enjoy movies that do a really good job recreating a time period and Hustle brought the late 70s to life fairly well. Excellent performances from the entire cast, and Amy Adams eye-fucked me through the camera like the dirty vixen I know her to be.

.... it'll make a small hole going in and a somewhat bigger hole coming out.
It would vapourize on impact.
The entry hole might be small, but then you'd have a ball of expanding hot incandescent metal gas, with the kinetic energy equivalent of a VW beetle travelling at 80km/h, slamming into the other site of your satelite/space station causing the exit hole to be much worse than the entry hole, - then you have rapid depressurization ripping the exit hole bigger.
Cheers
If the impacting object is moving at something like 40000 km/h a ball of incandescent gas (plasma, whatever) would not have much time to expand before shooting out the other side of the space station. It'd pass straight through in like a microsecond or something like that (modules of the ISS are only a few meters wide.)
Anyone else watched Cap yet? Managed to sneak in a showing last night and have to say that I was more engaged and left thinking about it and what's to come moreso than either Iron Man 3 or Thor 2. Seems like it will go some what to explaining what's going on in Marvel's Agents of S.H.E.I.L.D. at the moment (and possibly why the show has suddenly sprouted "Uprising" in the end of the title).

I saw it yesterday and liked it. I haven't watched the Shield series at all though. I enjoyed Thor 2 very much, but Iron Man 3 was a let down. I have a little problem with these stand alone movies, it now feels really artificial that the other Avengers don't show up. I mean I would think that Ironman would have been interested in showing up here and Captain in Iron Man 3... It's no biggie really, but somewhat annoying. Will Hulk get a movie too?
The movie was good. But to be honest these stand alone movies all feel like a small introduction to the big deal - the avengers movie. The after-credits scene only confirms this.
Must say, Scarlett Johanson is just perfect I her role.

I think Thor 2 and Captain 2 were so big in scope and production values that they didn't seem introductory movies at least not nearly as much as the first of their movies. pretty solid stand alone stuff imo. I didn't see the post credits scene. I was in a hurry so had to leave the theater and I figured I'm just going to watch it from the youtube, but so far I haven't been able to find that clip anywhere... I read about it, but if someone knows where to watch the post credit scene, give a link!
Well it basically just introduces two (super cool) characters that have already been advertised to appear in the next Avengers. Very briefly. Oh and something else I won't mention. Everything has already been mentioned on the web in some shape or form.
I always think the same thing. The entire universe was about to go boom in Thor 2... what were Tony and company doing?
i have seen the raid 1 and the raid 2.
it was AWESOME
the action scene is dialed to 11 in The Raid 2. Its action looks believable, not too much camera cut.
i just don't feel comfortable with the inconsistent blood/gore.
btw the story depicted in The Raid 1 and 2 is not too far disconnected from the reality in Indonesia. The corruptor does have high rank/power/control. The cops does corrupt.

in here, we do not "respect" the cop. We "fear" them and making joke of them after bribe them cheaply and scold our friends if bribe too much and praise our friends if can get out without bribery but tell them its a waste of time (because you need to go to the law office the next few weeks, must pay, cant dispute at all to the judge). Fortunately its getting better since this last 5 years
