Back to the Forbidden Planet

Over the last few posts we’ve covered the Fermi Problem and hypotheses, which of the hypotheses sci-fi likes to write about, and which of the hypotheses it’s strategic to write about. This brings us back around to Forbidden Planet.


As a species, we’re faced with a number of big problems that need solving. Some feel more abstract than others, but it sure would suck if we were wrong about that. And while sci-fi can be pure escapism, when it does, hopefully it serves as a mild indulgence rather than something which lets us ignore problems in the real world. As I’ve said before, it is part of my mission with this blog to get readers to not just watch sci-fi but to use it; to understand its effects and limitations; to decide how believable its scenarios are; and to think about the lessons you can take back with you to the real world.

This is why Forbidden Planet is such a stellar movie for me.

It is a singular example (in the survey at least) of humans encountering an ancient, vastly advanced, dead civilization through the “ruins” of its technology. There was no tense tête–à–tête diplomacy, or sexily-foreign green aliens to seduce, or any of those other Terran imperialist thrills.

I'm not exactly sure which of those two possibilities this image represents.

I’m not exactly sure which of those two possibilities this image represents.

I don’t want to demean its historical importance. It came at a time in cinematic history after a few decades where Hollywood created little more sci-fi than space opera for kids, and it proved enough of a commercial and critical success that suddenly sci-fi was a serious consideration for big budget attention. That meant broader reach, and more people thinking about speculative futures. (Heck, it meant enough serious sci-fi that I could keep a blog about the genre. So, you know, thanks for that.)

But more than its historical importance is that it’s the best model of a likely future. Just this past May, Adam Frank (an astrophysicist at the University of Rochester) and Woodruff Sullivan published “A New Empirical Constraint on the Prevalence of Technological Species in the Universe.” In the paper they note that the 1,284 new exoplanets discovered by the Kepler observatory scientists puts some lower-limit constraints on a few factors in the Drake equation.

Kepler-11 is a sun-like star around which six planets orbit. At times, two or more planets pass in front of the star at once, as shown in this artist's conception of a simultaneous transit of three planets observed by NASA's Kepler spacecraft on Aug. 26, 2010. Image credit: NASA/Tim Pyle

“Three of the seven terms in Drake’s equation are now known. We know the number of stars born each year. We know that the percentage of stars hosting planets is about 100. And we also know that about 20 to 25 percent of those planets are in the right place for life to form. This puts us in a position, for the first time, to say something definitive about extraterrestrial civilizations—if we ask the right question.”

Their work suggests that the odds are in favor of finding alien life—but finding evidence of it long dead. They suggest a shift in our attentions away from contacting a living civilization, towards cosmic archaeology. You know, like Forbidden Planet illustrates.

Number of Technological Species Ever in the Universe, from the paper.

Frankly it could stop there and be canonized for that purpose, but the film goes one better

We still don’t have great constraints for the other troubling component of Drake’s equation, and that’s how long technological civilizations tend to last. That question in turn raises the darker question of what tends to doom those civilizations. One possibility is that it is that technology itself is the thing, which is, again, what Forbidden Planet illustrates.

This is a blog about sci-fi interfaces, and I presume that readers are, like me, directly involved in shaping technology. So it is that this 60 year-old film has a one-two punch. It shows us both what the future will probably be like, and then turns our attention to something we can think about—and work to make right—now.

And that’s sci-fi we can use.


A Fermi strategy

In the first post I gave an overview of the Fermi question and its hypothetical answers. In the second, I reviewed which of the answers sci-fi is given to. In this post I compare the costs of acting on each answer.

Which should we be telling stories about?

Sci-fi likes to tell stories about the Prime Directive Fermi answer. But is it the most useful answer? Keep in mind that most of us are not working in space programs. For us, sci-fi is less direct inspiration to go build the most kick-ass rocketship we can, but rather inform how we think about and support the space program culturally and politically. With that in mind, let’s spend a little bit of time talking about the effects of confronting each hypothesis in our sci-fi. To be able to compare apples to apples, let’s apply the same thinking to each.

  1. What would be the call to action (if any) if this hypothesis is true?
  2. What if this is true, but we fail to act on it?
  3. What if it’s true, and we do act on it?

Warning: This will be long, but if we’re thinking strategy, risk aversion, and opportunity maximization (as we are) we have to be thorough.

Life is rare


All life is precious, Daryl.

These stories tell us to not get our hopes up about thrilling tales of space imperialism. We need to get our shit sorted, since, no, we won’t have peace treaties with Romulan Sith, but we will have our hands full dealing with our own worst natures and the weirdness of natural space problems like black holes and special relativity. While we go about this, we should take advantage of this freakish circumstance by protecting life for the precious thing it is.

The Fermi Paradox and Sci-fi

In the prior post we introduced the Fermi paradox—or Fermi question—before an overview of the many hypotheses that try to answer the question, and ended noting that we must consider what we are to do, given the possibilities. In this post I’m going to share which of those hypotheses sci-fi has chosen to tell stories about.

First we should note that screen sci-fi (this is, recall, a blog that concerns itself with sci-fi in movies and television), since the very, very beginning, has embraced questionably imperialist thrills. In Le Voyage dans la Lune, George Melies’ professor-astronomers encounter a “primitive” alien culture on Earth’s moon when they land there, replete with costumes, dances, and violent responses to accidental manslaughter. Hey, we get it, aliens are part of why audiences and writers are in it: As a thin metaphor for speculative human cultures that bring our own into relief. So, many properties are unconcerned with the *yawn* boring question of the Fermi paradox, instead imagining a diegesis with a whole smorgasbord of alien civilizations that are explicitly engaged with humans, at times killing, trading, or kissing us, depending on which story you ask.


But some screen sci-fi does occasionally concern itself with the Fermi question.

Which are we telling stories about?

Screen sci-fi is a vast library, and more is being produced all the time, so it’s hard to give an exact breakdown, but if Drake can do it for Fermi’s question, we can at least ballpark it, too. To do this, I took a look at every sci-fi in the survey that produced Make It So and has been extended here on, and I tallied the breakdown between aliens, no aliens, and silent aliens. Here’s the Google Sheet with the data. And here’s what we see. Continue reading

The Fermi Paradox

For its 60th anniversary I hosted a sci-if movie night at the Roxie cinema in San Francisco of the 1951 classic Forbidden Planet. It was delightful to see it on the big screen with the Roxie’s gorgeous projection system and hear that crazy soundtrack through their audio system.

After the show, I broke with my usual tradition of discussing any of the interfaces (after all, I’d already reviewed all of them on the blog years ago, and recently discussed the film in depth with the guys at Decipher Sci-fi) and instead discussed an idea that’s present in the film. In this handful of posts, I’m going to represent that content, but also add some additional content that there just wasn’t time for before we had to leave the cinema to make way for the next show.

Necessary Spoilers: In Forbidden Planet, a platoon travels to Altair IV to figure out why a 19-year old colony of scientists has gone silent. They meet Morbius, the only survivor of the original colony, and his daughter Altaira. They learn that Morbius has discovered the complete knowledge and technological remains of a long-dead, highly advanced civilization called the Krell. Through the Krell’s still-working machines Morbius has greatly enhanced his intelligence, but unwittingly unleashed an invisible “monster from the id” that has violently destroyed everyone but him and his family. Morbius refuses to return to Earth with Captain Adams, and so Adams grounds the mission while his crew uses parts of the ship to construct a communication device to ask for orders. During the downtime, with some truly wince-worthy 1950s slut-shaming courtship, Captain Adams somehow wins the heart of Altaira, who falls for it and defies her father and becomes engaged to the captain. Crushed by the betrayal, Morbius’ control of the monster wanes, and it attacks and defeats him. His world asunder, Morbius decides in his dying moments to scuttle the entire planet, including all traces of the Krell. From a safe observing distance in space, Adams, Altaira, and the surviving crew watch the explosion before heading back to Earth.

The movie presents one answer to a long-standing astronomical question,

“With 400 billion stars in our galaxy, and 400 billion galaxies in the observable universe, and billions of years of time since the start of the universe, even if only a very small fraction of stars produced advanced civilizations, where the hell is everybody? Why does space seem so devoid of life?

This question is commonly known as the Fermi Paradox. It’s not really a paradox in the logical sense, so it works better in discussions to call it the Fermi question. Continue reading

Report Card: Forbidden Planet

Forbidden Planet is an influential film not just because of its positive audience reaction and later cult success, but also because Gene Roddenberry has stated that it deeply influenced his massive science fiction property Star Trek, in look, general plot structure, and even some of the same effects.

The film is also notable for the introduction of Robbie the Robot, an anthropomorphic robot who was such a hit (and so expensive for MGM to create) that he warranted a follow-up movie all to himself, and inspired the creator Robert Kinoshita to make a similar robot for the long-running family-friendly serial Lost in Space.

But as much as we adore the nostalgic themes and effects, and as much as we recognize the influence of the film, our review must be of its interfaces, and for that it does not ultimately fare well.

Worst. Self-destruction mechanism. Ever.

When Morbius has taken a mortal wound from his monster and destroyed his “evil self,” he realizes that mankind is not ready for the power available to him through the Krell technology. Without explaining what he’’s doing, Morbius instructs Adams to “turn “that disc”.” Adams mindlessly obeys, and a plunger emerges from the floor near him.

Adams initiates the irreversible Krell self destruct mechanism.

Morbius commands Adams, ““The switch, throw it.”” Again, Adams does as he’’s told, and the plunger clicks into place as a red ring (the same red ring below the educator lever) illuminates. Then, and only then, Morbius explains that, ““In 24 hours you must be 100 million miles out in space. The Krell furnaces’ …chain reaction……they cannot be reversed.”” You think that with that kind of finality, he might have bothered to explain what was going to happen, or inquire whether the crew could make it out that far in that amount of time, but you know, science knows best.

The krell self-destruct warning signal is a silent, blinking red ring around the plunger.

Adding insult to injury, the complete warning system for this massive, solar-system-sized explosion consists of, in total, a silently pulsing red ring around the base of a plunger located in the heart of a hidden underground city behind a series of impenetrable doors sealed with combination locks. There is no klaxon, no lights seen elsewhere to indicate that your star system is about to go boom. I guess if you didn’’t know, you didn’’t really need to know.

The Monster from the Id

The plastic educator has a side effect that serves as the mystery at the dark heart of the film. Use of the device gives rise to ““monsters from the id,”” which manifest while the user is asleep and attack the sleeper’’s enemies. Our first clue to the origins of the monster appear when Morbius explains the Krell gauges.

The encyclopedia registers a negligible amount of power.

“Gauges line the curving walls of the lab in stacks of two,” Morbius explains, ““Their calibrations appear to indicate that they are set in decimal series, each division recording exactly ten times as many amperes as the one preceding it. Ten times ten, times ten, times ten, times ten, times ten, on and on and on, row after row, gauge after gauge.””

He turns on the encyclopedia and a small bit of light appears on the first gauge. He turns on the plastic educator and the gauge shows a little more.

Asleep, Morbius’’ id manifests as a horrible monster.

This explanation helps to set up the awesome power of Morbius’’ monster when we see Morbius sleeping in the lab, and sixteen of the gauges are lit up. (It’s 10^16 times more powerful than an encyclopedia.) We know the (then) unbelievable technologies showed the barest sliver of a reading, and here they are blasting power to…somewhere.

After waking, both Morbius’’ monster and the power gauges fade.

The connection is severed as Morbius awakens, and within seconds the monster fades and the gauges behind him dim one by one.

Adams wrestles Morbius into the seat of the educator.

This dramatic link is underscored when the monster has come into the underground city to destroy Morbius, Adams, and Alta. As Adams wrestles Morbius down, we hear the angry pounding of the monster against the vault like doors, and see the gauges glowing and fluctuating wildly in the background.
