Film review: “Interstellar”

November 19, 2014

“Any sufficiently advanced technology is indistinguishable from magic.” – Arthur C. Clarke

This quote applies, of course, to any number of science fiction films over the last fifty years. But I’ve seen so many reactions on the interweebs to this movie that seemed to be so wrong headed that I wonder if maybe there are several different versions of the movie out there, and I happened to see the one that actually used an extrapolation of science.

Physicist Kip Thorne and producer Lynda Obst started out, much like Kubrick and Clarke, to make a real science fiction movie that was based on fact, or at least logical extrapolations of what we know right now. After a bit, they attracted Steve Spielberg, who in turn suggested Jonathan Nolan to work with them on a screenplay. Ultimately Spielberg had to leave the project, and eventually Nolan got the script to his director brother Christopher Nolan. After some legal wrangling between Paramount and Warner Brothers, the film finally got started. Thorne had many discussions with the Nolans, the effects team, and cast members as the film progressed. For many members of the audience, it probably would not have been necessary to go this far – audiences today will suspend their disbelief for a lot of nonsensical pseudo-science. But the fact they did makes it that much richer for me, and hopefully for a lot of other folks as well. Thorne even wrote a book elaborating on the process, called The Science of Interstellar. I recommend it; not only does it give a good overview of the science used as a basis for the movie, but it also demonstrates how much hard work goes on behind the scenes in a film, sometimes for decades before the film comes out.

Let me say at the outset that I enjoyed the film a great deal. It’s long, at over 2 hours and 45 minutes, and early on it seems a little slow. However, I think that’s just the way I perceive it after all the cgi-laden action/adventure films that have come out over the past decade. This movie doesn’t start with a bang and then just keeps running along. It takes the time to build the relationships in Coop’s (Matthew McConaughey) family for us. However, it seems to take a much shorter time for Coop to be sold on the idea of what probably will be a one-way trip through the wormhole. But then, Michael Caine can be very persuasive, of course!

If you want a recap of the plot, you can always go here. Rather than that, I’d like to reflect on the main theme of the movie, which is, to me, “we can save ourselves with a little bit of time travel, just not the time travel you think.”

Nobody physically goes back in time. (In fact, Thorne is one of scientists best known for explaining why we won’t be able to do that.) However, that doesn’t mean that information can’t be sent back, in one way or another. All you need is a civilization sufficiently advanced to give a father a way to send some information to his daughter – if the father is in the right place, and if the daughter is the right daughter.

WARNING: SPOILERS AHEAD! I’ve read that some folks who have seen the movie took the bit of speculation about the nature of love as being a tangible, physical force that transcends time and space – presented by Anne Hathaway’s character – and ran with it. Sorry, y’all; you weren’t paying attention later on. It is made abundantly clear that the lines in the dust in Murph’s room were created by artificially-created gravity waves. No “Power of Love” here. I can understand some of the confusion, though: gravity is just as difficult to perceive, and no more easily controlled, at least by us. But not by the post-humans. (That’s what I call ’em. For a long time we are sort of led to believe they are some kind of super-beings just doing us a favor so we don’t die off. Coop makes the mental leap that they are our descendants, greatly evolved.) We never see them, and we only really see one effect of their presence. The “time lattice” Coop uses to communicate with Murph is apparently constructed by the post-humans only for that purpose, so he can give her the information she needs for a breakthrough that allows humanity to finally leave Earth, and apparently just in time.

In a way, this is the “transparent aluminum” storyline: In Star Trek IV, Scotty needs “transparent aluminum” to construct a tank for the whales. He gives the formula to a 20th century chemist/engineer so that he can create what Scotty needs. When asked by Dr. McCoy if this was messing with the timeline, Mr. Scott replies, “How do you know he didn’t invent the thing?”

I suppose transparent aluminum isn’t as big a thing in the 24th century as radio is for us. (Although if asked, most people would identify the inventor of radio as Marconi, if they had any idea at all. Grrr. Tesla, folks, Tesla. Look it up.) Still, Scotty wasn’t worried by bootstrapping materials science and creating the classic causality loop.

To make sure that humanity doesn’t die out by being stranded on Earth, the post-humans leave messages for Murph that subtly suggest to Coop that his trip through the wormhole might not be the sheer folly it seems. Therefore, he goes, lots of crazy stuff happens, and he in desperation makes the dive through the black hole’s event horizon. There they have set up the commo lattice – referred to in the film as a tesseract – for him to use to provide signals to Murph at various times of her life, including those that influenced him in deciding to go in the first place. He also can send the data the older version of Murph needs to make the breakthrough in mastering gravity so that we can get off this rock. He does this by manipulating the second hand on a watch through gravitational effects, sending a lot of data collected from inside the event horizon. It seems to take him only a short time to do this, but as we know, time inside a black hole’s event horizon is different from outside it.

So at the end of it all, no aliens – but something that started out as humanity has to help get its ancestors off the planet, or they won’t exist, and they placed the wormhole in orbit around Saturn just for that purpose. Seems like a long shot, but if they had the history of what had happened at that time, all they had to do is make sure the history had a little help to play out correctly.

Those of you who are believers in the “Many Universes” hypothesis probably won’t buy into this as much. In another universe, no wormhole; in yet another, no Coop to save them, etc. If that interpretation could be brought into the plot, the tesseract would have shown Murph in her room in many, many more versions of the situations that first and last provided communication with her. But the film stays firmly rooted in a traditional causality.

It’s not a new idea, but it certainly is played out in a refreshing fashion. I was happy to see a plot that took that much of the audience’s attention to follow in a big mainstream movie.

There are the nitpicks. First, Coop’s training sucks. They pretty much throw him into the ship with three other people, and away they go. That is necessary so that he can be the space cowboy he needs to be, flying the Ranger by hand at several key points in the movie.

Questions have been raised about the Ranger. Why did it need a big chemical-powered, multistage booster to get off Earth, yet takes off and lands under its own power on several other planets, including one with a surface gravity of 1.3 G? I have a possible answer, though it isn’t covered in the movie: antimatter.

The ships are a combination of tech we have now (Rangers are covered with shuttle-like protective tiles, for example) and very high tech (robots with advanced AI.) We know that making antimatter, at least the way we know we can do it right now, is very slow, requires very large equipment, and is very power-hungry. Maybe the Ranger could have taken off on its own, but say it uses 25% of its available fuel to do so. No more fuel after that. Let’s save some by using a sort of pseudo Saturn V that we had laying around. We may have fueled it with the last antimatter we could produce.

The Ranger has little room for fuel stores, so fuel has to be something very energetic, like antimatter, but it can’t take up a lot of space. Maybe a couple of tanks of reaction mass to interact with the antimatter can be squeezed in. Hydrogen is the best choice if the antimatter is really anti hydrogen, but it isn’t very dense so the tanks have to be insulated like crazy and be larger than LOX or H2O tanks would be.

The other nitpick is tidal effects. On the first planet the explorers are confronted with a tidal wave 4000 feet tall. The planet is too close to the black hole – close enough that time slows down a lot, and tidal effects on the ocean are enormous. The same tidal effects should affect everything on the planet, so it eventually will be torn apart. That to me means it isn’t a good candidate for a new home for mankind.

Also, apparently the light from the black hole (huh?) is bright enough to provide light bright as day – at least, a cloudy day in Iceland. Where is that light coming from, really? You would need it to grow crops. None of these planets sounds particularly pleasant or survivable in the long term!

My major gripe about the film is the score. Hans Zimmer was apparently asked by Christopher Nolan to do something unique. He’s done that if unique means boring, loud and simplistic. Sometimes it was so loud it covered important dialog. The score lent more of a feeling of slowness to the movie as it slogged along, repeating the same phrases over and over again. Did Zimmer listen to too much Philip Glass? I would have thought a score like Alan Silvestri’s for The Abyss would have been appropriate, instead. I think this movie would have been a complete knockout, Oscar-worthy, if the score wasn’t so annoying and boring.

Nolan likes using IMAX cameras, he likes using real film over digital recording, and he likes using practical EFX over CGI when possible. All are great, but remember, far more viewings of this movie will be on TV screens than in the theater. Until we all have our 85 inch 4K HDTVs that extra quality won’t be noticed…but a bad score will be.

In summary, I was pleasantly surprised. It’s not the landmark film some people have said it is, but it’s very good, and I highly recommend it to you.

Audiobook recommendation: “Solaris,” by Stanislaw Lem

September 15, 2014

I’ve been away from this blog for over a month and a half, because life has a habit of intervening. We had new windows put in the house and a host of smaller projects, some which we did and some which we hired out. In any case I had to be around a lot of the time and my time was not always my own. Oh, and I set up a couple of web sites for organizations. Maybe more on that in another post.

What compelled me to write tonight, though, is that I tend to listen to audiobooks when traveling alone, or working in the yard or garage. I’m at the beginning of marching band contest season, so I will be spending some time on the road in the car. Music doesn’t keep me as alert when I’m driving through the fields of Indiana as audiobooks do.

Some months ago I set up a Platinum account at Audible.com. I have six credits built up that I haven’t used to select books yet, and I’m behind in my listening, so I may have to downgrade that subscription in a few months.

Sort of on a whim I bought the audiobook of “Solaris,” by Stanislaw Lem, a Polish science fiction author who wrote the book in 1961. It was translated into English in 1970, but Lem himself didn’t care for the translation. (That translation was actually taken from a Polish-to-French translation, with results you might expect. Maybe 80,000 words or so of the telephone game.)

For the 50th anniversary of the publishing of the book a new direct-to-English translation was finally commissioned by Audible, and made by Bill Johnson, with the cooperation of the Lem Estate. It was read by Alessandro Juliani, who I know best as Felix Gaeta in the reimagined Battlestar Galactica. The book is written in the first person, and Juliani reads it as if he is telling you the story himself, in a generally quiet, intimate voice. It seems very appropriate to the tone of the book.

Short synopsis, without spoilers: Psychologist Kris Kelvin is called to the human research station hovering just above the planet Solaris, a very unusual planet in a stable orbit about two stars, one red and one blue-white. The planet has been studied off and on for almost a hundred years, and the research team on the station is now reduced to only three. One of these researchers has asked for Kelvin’s help, but does not disclose why.

The planet is almost completely covered by an ocean of a gelatinous substance. It has been theorized over the years that the ocean is somehow sentient, since it builds huge structures within itself and then destroys them, but no means of communication can be found. The ocean is sometimes responsive to human stimuli and sometimes not, and eventually the teams of researchers lost interest in the planet out of frustration. Various theories about what Solaris is and what it is not have been proposed, but nothing definitive has been determined in decades.

Kelvin finds the two surviving members of the station’s crew to be furtive in answering his questions. Both seem distracted, almost haunted, but are unwilling to say what is bothering them. The third member, the one who called Kelvin in the first place, is dead, apparently at his own hand.

I won’t spoil the story for you. If I say any more, it will spoil it, at least a little. Let it suffice to say that Lem created an amazing world, one that even today, with our supposed advanced technologies, seems fresh and new – and presented problems for humans to deal with on a very personal level as well.

There have been two film versions of the book. One was made in 1972 and was Russian; the other is a 2002 version starring George Clooney and directed by Steven Soderbergh. Both focus on the personal issues of the characters and give very little time to the awesomeness of the planet’s intelligent ocean itself. I’m not terribly interested in seeing either; this happens with movies very often – we must make movies that are “character-driven,” even if we have to distort the science terribly to do so.

I’ve not finished the audiobook yet, but I think it is so good that I recommend it even before finishing it. I don’t know how the story ends, myself, at least not yet. I’ve toyed with ideas of how humans might deal with extraterrestrial intelligence that is completely impossible to understand myself. Most aliens are people in rubber masks, even in “hard” science fiction books. What happens if what we find is so alien as to be impossible to communicate with?

The best thing you will see on the internet today

I found it on io9.com: velociraptors replaced by cats.

I’m just thinking about other movies where this would be awesome…

Alternate Universes that we don’t think of as alternate universes

December 5, 2013

There are many books and short stories having to do with”alternate universes” – timelines similar to our own but in which a single historical even changes, and over time the results of that action have large consequences. There are the Sidewise Awards, given in both long and short form.

I won’t bore you with a history of alternate history. You can google it faster than I can write about it. However, you might want to check out the work of Harry Turtledove and Robert Conroy, at least.  Maybe one of these days I will list some of my favorites.

But here I’m talking about something else, primarily television shows. Almost all political series that take place in the present day could be called alternate history. Take “The West Wing,” which was running when the 9/11 attack took place. There wee references to it, but not much, and it did not profoundly effect the timeline in the show after that – even though it did in our timeline.

But here’s my favorite: “In the universe of “Star Trek,” no “Star Trek” ever aired.” I don’t remember where I first read that, but I’ve pondered it over the years in idle moments. For example, apparently manned space exploration continued in ST timeline more extensively than in ours – it was good enough to loft a sleeper ship in the late 1990s to get rid of Kahn Noonian Singh and his motley crew. There was that pesky nuclear war around that time, or after; and the Genetics War before Kahn was exiled, but even that didn’t keep Zephram Cochrane from building a warp ship from an old Titan missile.

Some like to say that ST inspires us toward that sort of Utopian vision apparently held by Gene Roddenberry. It’s more complicated than that, but I think it is safe to say that ST didn’t really inspire us to maintain manned exploration of space – the Trekkers couldn’t even get NASA to name a real space shuttle after the Enterprise. (The one they named was a test article used for glide tests.) Perhaps a series taking place in the nearer future would have done so more effectively.

Sherlock Holmes, in all his manifestations – novels, stories, films, plays, radio shows, television – existed in a particular world. Usually, as in the original, it was very close to actual history. Later versions had him fighting Nazis and working in a more steampunk Victorian England. The two contemporary versions – “Sherlock” in the UK and “Elementary in the US – apparently take place in a world in which Sir Arthur Conan Doyle wrote about other things. Perhaps his medical practice took off faster, or maybe he decided to stay in London rather than moving to Southsea, and became involved in other activities.

Still, every time someone in “Elementary” is introduced to Holmes, their lack of surprise at the name, except for its odd sound, seems very strange to me.

Some interpretations of quantum physics imply that there is a multitude of universes. Maybe in one of them Barak Obama lost the Senate election to Jack Ryan, and he stayed in the Illinois General Assembly…

More prescient than even he would have expected

November 19, 2013

demonhauntedIt is well-known that Dr. Sagan was not religious – he described himself as agnostic, believing he had seen no proof of a supreme being. His 1995 book, The Demon Haunted World, was about using the scientific method and critical thinking instead of superstition and pseudoscience.

Admirable goals, and Carl Sagan was very articulate. His Cosmos series and book (PBS, 1980) probably did more to to help laymen understand the universe than any previous media program. (He also wrote the novel upon which the Jodie Foster film Contact was based.)

But I doubt he would have expected that his description of America in the quote above would have happened so quickly, or that we got there in the way we did. He seemed to believe the “New Age” trends he saw in the 1980s and 90s might grow, and that the much-publicized decrease in our ability to educate our students would result in an overall dumbing down of America. He himself did what he could to keep that from happening. I doubt he thought, though, that only two decades after he wrote those words we would have fallen so far and so willingly.

Hat tip to Scott Lowther and his “Up-Ship” blog for tipping me off to this one.

Starbuck’s twitter controversy over gun safety

June 11, 2013

Katee-Sackoff-Joins-Female-Expendables

Katee Sackhoff (Starbuck on the great reboot of Battlestar Galactica) recently commented on Twitter, advocating gun safety after a four-year-old accidentally killed his father with a gun. Reports said that she lost half her Twitter followers – about 10,000 – due to a debate that ensued about gun safety versus gun control.

Nothing I read made Katee sound nutty. She just realistically stated that gun control, at least the way it is discussed today, isn’t likely to happen in the US. But as we know, a lot of folks are crazy over gun control, for a variety of reasons.

And apparently Katee actually gained followers – about 10,000 – during the tempest in a Twitter teapot. And that she really has over 100,000.

I didn’t have to post this. I had two points – first, that gun control advocates can be pretty rabid. (If gun advocates were as rabid, they would be shooting things up all over the place.) Second, that Katee Sackhoff is pretty damn cool. (Currently she’s starring in Longmire on A&E.)

Few posts over the next few weeks

February 28, 2013

Sorry, campers, I know you hang onto my every word. Family medical issues will keep me away most of the time until about May 1. I know you can hang on that long without my observations!

I really recommend that you check out Jerry Pournelle, at www.jerrypournelle.com. I think he’s the original blogger, and his commentary and that of his readers covers science, science fiction, politics, music, health care, education…a very wide range of topics. He is a very wise man and a kickass hard science fiction writer. In fact, he and Larry Niven owned most of the hard science fiction real estate for about 20 years, and both are still writing, together and separately!

See you around the intertubes. Keep your heads down.
