Gravity: Can Film Ever Get the Science Right? 438
dryriver writes in with a story lamenting the lack of accurate science in movies. "The relationship between science and science fiction has always been tempestuous. Gravity focuses on two astronauts stranded in space after the destruction of their space shuttle. Since Gravity's US release (it comes to the UK in November) many critics have praised the film for its scientific accuracy. But noted astrophysicist Dr Neil deGrasse Tyson, director of the Hayden Planetarium at the American Museum of Natural History in New York, had several issues with the accuracy of Gravity's portrayal of space. Through a series of posts on Twitter, Tyson — who later emphasized that he 'enjoyed the film very much' — highlighted various errors. He noted the Hubble space telescope (orbiting at 350 miles above sea level), the International Space Station (at 250 miles), and a Chinese space station could never be in line of sight of one another. On top of that, most satellites orbit west to east, yet in the film the satellite debris was seen drifting east to west. Tyson also noted how Sandra Bullock's hair did not float freely as it would in zero-gravity. This is arguably not so much an error in physics, but a reflection of the limitations of cinematic technology to accurately portray actors in zero-gravity. That is, of course, without sending them into space for the duration of the film. The Michael Bay film Armageddon is known for its woeful number of inaccuracies, from the space shuttles separating their rocket boosters and fuel tanks in close proximity to each other (risking a collision) and to objects falling on to the asteroid under a gravitational pull seemingly as strong as the Earth's. More than one interested observer tried to work out how big the bomb would have to be to blow up an asteroid in the way demanded in the movie. Answer: Very big indeed. Nasa is reported to have even used Armageddon as part of a test within their training program, asking candidates to identify all the scientific impossibilities within the film."

It's not a problem of suspension of disbelief, it's a problem with lazy writing. As a writer, you may define your world however you want to, and I'll accept it, but you cannot violate your rules. You want to write about an alien who can fly when he's in a planet orbiting a yellow sun? If those are your rules, that's fine, I'll accept them. I know nothing about this alien species of yours other than what you've told me, I'm willing to accept their biological structure makes use of some physics that's unknown to us. However, when this alien saves a human who fell from the top of a skyscraper by catching them 2 meters off the ground, you didn't explain how that's any better than hitting ground. You want to write about humans who are trapped in a virtual world by sentient AIs and don't know it, and how liberated humans are able to enter this world and hack it just enough to perform feats which seem impossible? That's alright, that's your setting. However, when one of those humans starts performing those impossible feats in the real world, you failed to explain how that would work.
In a way, the more detached you are from reality, the more difficult it is to screw up. If you're writing about a world of hobbits, orcs, elves, dragons, and dwarves, there's very little you can possibly do that's going to make me question it. Everything you do in that setting I take as simply additional information that I didn't know about that world. The only way you can screw that up is by contradicting whatever you've established before. If you tell me all dwarves are all short, and then introduce a dwarf character that happens to be taller than an elf, you better have an explanation. In the very same way that you should have an explanation for why a woman floating in zero-g doesn't have free-floating hair.

I'm pretty OK with Gravity though. The movie came out well after the last space shuttle mission, so everyone should know that bird is not still flying. Gravity is therefore set in some alternate universe where more shuttles were built and the program is still ongoing, and also so the Hubble and ISS may have been placed in more similar orbits, the manned maneuvering packs designed differently and retained longer, the Chinese decided to locate their station close to the ISS, etc.
It's like an early Tom Clancy novel. The Japanese never really built a covert nuclear weapons program, but flying an apache 12 feet above a railroad track and having AWACs style radar think it's a bullet train until it pops straight up at them might actually work all the same. Clancy may have been utterly fictitious in attributing the sorts of motives he did to the Japanese, but he made damned sure to check the top speed and operational ceiling of his helecopters, whether they could actually be deployed by sub, and many other things about them.
In Gravity, we had:
1. the death of the mission specialist by having his head punched out, with a pretty realistic injury appearance.
2. The rest of the shuttle crew's deaths by decompression, also realisticly portrayed and with the fact that they would normally not be suited up just because the bay doors were open included. Note that in that scene, most or all of the bridge instrumentation and lighting is down - which may explain one of the supposed inaccuracies - why automatic stabilizing jets didn't fire when the shuttle was first hit, as it looks like the same impact seems to have killed both the bridge crew and the electronics.
3. The use of a fire extinguisher as an improvised propulsion unit, and our heroine's having the sense to grab one rather than push it away. If it's not technically accurate as to how much thrust it would supply, at least it had a real science feel as good as a Clarke or Heinlein story.
4. A realistic fire in space, with a lengthy smouldering period as 0-G kept the smoke from leaving the vicinity of the flame, and eventual flashover as it found sufficient oxidizables to outrace the smothering effect.
5. Realistic air pressure aboard the first Soyuz design capsule (what, you thought spacecraft are pressurized to a full 15 PSI?). Hypoxia in a young healthy adult and its different symptoms from such conditions as Emphasemic Hypoxia with accompanying Peripheral or Organismic Cyanosis treated with medical accuracy. (Periods of recovering from brief unconsiousness to full mental awareness are documented in highly athletic people suffering from suddon onset Hypoxia and not normally in cases where the cause is age or illness, but that's an unusual situation with the ambiguous "religious vision" as part of it, so whether the film got that intentionally right or just hit it by accident is up to the viewer).
6. A Soyuz style capsule stabilizing heat shield down from a tumble in the same manner as a boat tail bullet as it hits denser air, (Something the original Russian designers have long bragged about it being designed to do better than the Apollo, which was in turn supposedly better than the Gemini series).
7. Debris begins to glow with heat at altitudes where the air is still to thin to conduct much sound. Realistic hypersonic decelleration booms, increasing in volume as the air begins to bite,and unshielded debris shredding and vaporizing follow, and it all happens in very accurate realtime with the visuals confirming what the craft's altitude should be as it begins grabbing real air, begins to slow and the last bits pass it by. Time for the shot is textbook standard reentry time if the guidence systems actually get everything right.
8. Just getting the fact right that the Soyuz design is meant to land on solid ground is worth a few brownie points.

Apollo 13 had a huge advantage these other stories don't: it wasn't fiction nearly as much as it was a recreation. They didn't have to write the drama into the script, they didn't have to invent science, they didn't have to invent an oxygen tank stirrer that might explode (which sounds like a plot device from ST:TOS). They even had first-hand reports from the scientists involved. They didn't have to fake anything.
If you're filming a space drama from scratch, there are a lot of gaps you have to fill in. In a science fiction movie, technology is always just beneath the veneer of the characters, embedded in the very set. Their lives are intertwined with the tech, dependent upon it for everything, so it's always visible on screen, and in the back of the audiences' minds - will the tank run out of air? Will a micrometeor strike rupture the hull? But if that mission has never taken place, the tech is imaginary. We think a manned mission to Mars would require X and Y and Z, but we've not done it yet. That leaves some tech up to the imagination of the production designer.
2001 did a phenomenal job incorporating imaginary tech into the sets. The rotating set shots were indeed brilliant. Even so, how many astronauts would you need to enter an actual 2001-era CPU cabinet to shut down a rogue AI program? While he nailed the vision of centripetal gravity, he completely missed on some of the most important technical advances. In 300 years would Lt. Ripley really need a separate room to access MOTHER? Would MOTHER really still be displaying on a green screen CRT?
These days it only takes a few such mistakes to break the tech-savvy audience out of their willing suspension of disbelief.
You can say "we have a great story, let's have these great actors and actresses carry it. Behind them, we'll place some blinking lights and switches that look all spacey, paint them white, and we'll get ILM to add smoke and rocket exhaust, but for the most part we're not going to worry about it." Or you can say "let's take the design for an actual rocket that might be used for this mission, and build the set to resemble it. For the plot devices, we need a panel to access the cryo stirring control valve, and a different hatch to access the electrical bus, and each should contain all the appropriate parts, lines, hoses, and wires in our imaginary spacecraft. The astronauts are expected to live 40 years, so we'll need 372 cubic meters of storage representing food and water, 69 working CO2 scrubbers, the tanks will need to hold 4.3 million liters of fuel, etc. We'll film all the scenes on the Vomit Comet so that we don't make any mistakes regarding zero-G." They end up spending 30% of the budget on scientists and engineers and sets, and 60% on a zero-G film crew, and they haven't even told you the story yet.
I hope you like Polly Walker and Eric Stoltz, because they're the only actors they can afford on what's left of the budget.

Listen, I'll be the first to point out or notice glaringly dumb science inaccuracies in films, but going after Gravity on this count is pretty ridiculous given that the filmmakers knew *exactly* what they were fudging into order to, you know, giving us two hours of decent thrills instead of 2 minutes of, OK they're all dead now, or 2 hours of them drifting in space dying of asphyxiation. It's fine to point out the inaccuracies in order to inform people about the actual facts, but implying they somehow should have gotten it absolutely right is dumb, and really, the hair not floating? Come one, suspension of disbelief anyone? Besides, who's to say in the universe of the film that all 3 stations weren't in the same orbit very close to each other from some inexplicably crazy reason. :) That's really the only way they would have had a chance of survival, or at least tell a compelling story in that circumstance. And either space shuttle was still in service in that universe or it took place in the years it was in service (gasp movies can show things that aren't happening right now?). To me the silliest things were the Chinese station somehow being knocked into such a lower orbit that it was starting to immediately deorbit, but I see where they wanted to introduce yet another against the clock obstacle, and Clooney have to let go to save Bullock.

It's pretty much impossible to do a space disaster film with anything close to modern technology. It basically boils down to "Everything works exactly as planned or you die." Yes, we have Apollo 13 but most disaster scenarios are going to be more like Challenger and Columbia.
Westerns do it (Score:3)
Most of the westerns I have seen have no trouble getting the science right. Nor, for that matter, do romantic comedies or crime dramas.
The difference, of course, is that everyone is fairly familiar with the physics of bullets and the fluid dynamics of smoke in the wind. Once space travel reaches that level of penetration, the movies will have no trouble getting it right too.

No, they don't.
How many westerns or crime dramas have you seen where somebody manages to outrun an explosion? Or where an explosion involving high explosives and no barrels of flammable liquid manages to end up with a giant fireball? Or where a bullet impact knocks the recipient flying backwards? Or where something as flimsy as a car door protects against a rifle bullet? Or drywall against a pistol bullet? Or the hero takes a 20-foot fall and gets up with nothing broken or sprained? Or somebody div

This is why nobody ever invites Neil deGrasse Tyson to the movies. It was a great movie. If your biggest quibble is that they made navigation line of sight to avoid tedious scenes full of calculating orbital mechanics, you're a killjoy.
Artist Rendition (Score:2)
I don't so much mind a work of fiction bending science to align the story. That's what fiction does.
I'm much more bothered by science adding fiction to their work by providing an 'Artist Rendition" of a planet that might be like Earth. NASA sees a reddish speck near a star and suddenly the article has a picture of terrain, instead of a picture of a speck. That is a crime.
These science in fiction dicks need to stop picking on the wrong people.
Thank you for listening.

Bowman's head not exploding when he has to blast himself into Discovery's airlock?
The fact Discovery has an area that rotates fast enough to simulate 1G for the sleeping crew as well as Bowman and Poole to keep from losing bone mass?

Haven't seen the movie (yet) so I can't comment on the exact scenario, but, wouldn't debris be moving "east to west" if you were moving west to east faster* than it was?
Of course, if you are at the space station when it is destroyed.... given that each orbit is uniquely defined as a function of velocity and radial distance (before anyone forgets: velocity is a vector quantity, so

"Damn, that *space realism movie* had some minor/moderate inaccuracies... I was really disappointed [that they didn't spend 500 million on production cost to really film he whole movie in microgravity]."
For space sake... there seems to be no way to please certain people.
If you are a NASA, space-science, space-exploration supporter: There is a time to be scientifically brutal and honest, and a time to sell cars (to borrow the phrase from Steven Spielberg, among others). When something like Gravity gets made, spend 95+% of time lauding the good aspects of the film... less time preening your own scientific ego about how much you know about space.

Science Fiction is a sub-genre of Speculative Fiction. The idea is to twist a few things from reality and then make a story about it. With SciFi, those twists are usually related to technology or science (speculating on what might happen in the future at technology develops, for example). Fantasy is another sub-genre, where the twists are more supernatural. Of course, I'm making broad generalizations here, but the concept should be about right. All fiction is speculative to some extent, of course, but
