In this edition of Geek Jargon 101, I’m going to talk about one of my favorite subjects, parallel universes. This is not going to be a scholarly discussion of actual scientific theories about the existence of parallel universes - which I find very dull and have little interest in. (You can read more of what I have to say on that subject here.) I'm talking about parallel universes as they're portrayed in fiction.
I think we're all familiar with the parallel universe concept. It's the idea that somewhere, in another dimension in space, there exists a separate universe that is similar to our own, but differs in significant and entertaining ways. For example, during the last half of the twentieth century, writers loved to concoct alternate histories where the Nazis won World War II and went on to conquer all or part of the world. I call this the "Nazi Planet" genre. There are two reasons the popularity of this genre. First, World War II was one of the major turning points in human history. And second, everyone agrees that the Nazis were the greatest real-life supervillains ever. They tried to conquer the world, they killed millions of people, and they all looked great in their Hugo Boss uniforms while doing it!
Any time you have two or more parallel universes, they are collectively referred to as a "multiverse." Growing up, I assumed this term originated in comic books (where I was first exposed to it). But it turns out, the term was coined all the way back in 1895 - by a psychologist, of all things!
The parallel universe has been a sci-fi trope for decades. Many of us were introduced to the idea by the Star Trek episode "Mirror, Mirror" (or, a generation later, by the very similar Super Friends episode "Universe of Evil"). In "Mirror, Mirror," a transporter accident sends Captain Kirk and his landing party to a parallel universe which is socially and politically the opposite of the one we're familiar with. There, the Enterprise serves not the peaceful United Federation of Planets, but the warlike and imperialist Terran Empire. The crew members are all murderous, conniving, and disloyal - the exact opposite of the Star Trek cast we're used to seeing. Plus, Spock has a goatee!
Here's your Atomic Gadfly Travel Tip for the week. If you're ever worried that you might've been transported into an "evil" parallel universe, just go around to everyone you know and see if any of them have goatees or eyepatches or facial scars they didn't have the day before. Especially goatees! If we've learned anything from television, it's this: if your Aunt Rosie grows a goatee overnight, you're probably in an "evil" parallel universe! (Or she could just be going through menopause. You should probably make sure before you go on a shooting rampage at Thanksgiving dinner.)"Evil" parallel universes are my favorite kind, because I like seeing familiar heroes and villains in reversed roles, with the good guys getting to act like scumbags for a change. That's why I'm looking forward to the upcoming DVD release of Justice League: Crisis on Two Earths, an animated movie where Superman, Batman, and other DC Comics icons will battle their evil counterparts from another dimension.
The parallel universe idea has become more mainstream during the last 15 years. In the late 1990s, the TV show Sliders featured a group of interdimensional travelers who visited a different parallel universe every week. Parallel universes were parodied in episodes of The Simpsons, South Park, and Family Guy. Perhaps no one's doing more to popularize the parallel universe concept right now than J.J. Abrams. Alternate timelines figured prominently in his 2009 Star Trek reboot and in recent episodes of Lost. His new show, Fringe, deals with a shadow war waged against us by the inhabitants of a parallel world where the 9/11 attacks never happened.
From the Sliders episode "The Exodus, Part One" in which the team travels to a parallel universe where Earth is about to be destroyed by pulsar radiation. Also, the episode where Kari Wührer joined the cast - which was the exact moment I suddenly became interested in watching Sliders.
Parallel universes go by several different names. You just saw me use two of them, "alternate timeline" and "parallel world." Some others are "alternate reality," "alternate history," "parallel dimension," and, if you want to get really fancy, "separate plane of existence." These terms are often used interchangeably, but for the sake of this discussion, I'm going to use a few of them to describe specific categories of fictional parallel universes.
Alternate Reality. I use this term to describe a parallel universe that is radically different from our own. Geography and topography may be unrecognizable. Civilization may be at a different level technologically. It may be inhabited by supernatural creatures. Physical laws that govern our world may not apply. Yet, everyone you encounter there will speak modern English. Examples of "alternate realities" include Oz, Narnia, and Wonderland from the novels of L. Frank Baum, C.S. Lewis, and Lewis Carroll.
Alternate History. This is a parallel universe which closely resembles our own, but in which historical events have unfolded slightly differently. "Nazi Planet" stories like Philip K. Dick's The Man in the High Castle and Robert Harris' Fatherland would fit in this category. So, too, would Watchmen, which is set in an alternate version of 1985 where Richard Nixon is still president, costumed superheroes have existed since the 1940s, and the Vietnam War was ended by a godlike being called Dr. Manhattan. These examples are self-contained works of fiction. But what sci-fi fans really love is to see familiar characters cross over from their own universe into a strange parallel universe, then deal with the culture shock.

From a 1973 issue of Justice League of America: robot superhero Red Tornado meets robot Hitler, ruler of Earth-X, in a parallel universe where the Nazis won World War II.
Alternate Timeline. In fiction, there are basically two multiverse models. In one model, all the parallel dimensions that make up a particular multiverse came into existence at the same time, and have co-existed ever since. (Which leads to the question, did one Big Bang create the entire multiverse, or was there a separate Big Bang for each dimension within the multiverse?) In the other multiverse model, you start off with one universe. Any time there's a divergence in the time stream, a new parallel universe forms as an offshoot of the original. These offshoots are "alternate timelines." They're usually the result of mucking-about by time travelers who come from the future and alter the course of historical events. This is what we saw in the last Star Trek: Romulans came from the future, killed Kirk's dad, and blew up the planet Vulcan. The result was a new timeline, separate and apart from the original Star Trek timeline depicted in previous movies and TV shows.
Of course, time travel is another sci-fi trope. Stories where time travelers alter history generally fall into three categories, and I'll discuss all three when I continue this discussion next week. After that, I'll also talk about "Earth-Prime," the fictional concept of a "prime" universe from which all other parallel worlds emanate. In the meantime, here are links to the rest of the Geek Jargon 101 series.

Michio Kaku, the current rockstar in the field, is a very entertaining writer and speaker. I always enjoy listening to him on Coast to Coast AM, sandwiched between interviews with UFO abductees and Bigfoot investigators. But he's not out there collecting data and testing hypotheses - you know, the things a real scientist does. He's just regurgitating ideas that have been prevalent in comic books and sci-fi stories for the last fifty years. Arthur C. Clarke was also an entertaining writer with a scientific background, but nobody's going around pretending like
In the early '70s, the Planet of the Apes franchise was huge. DC wanted to do a comic book adaptation of the film series, but didn't get the license. It ultimately went to DC's archrival, Marvel Comics. But that didn't stop DC from putting out their own Planet of the Apes knockoff.
Although Jack Kirby created Kamandi to cash in on the popularity of Planet of the Apes, the germ of the idea had existed long before. Kirby published a very similar story in a 1957 issue of a comic book called Alarming Tales, years before the first Planet of the Apes movie or the 1963 novel on which the movie was based. Kamandi, himself, was recycled from Kamandi of the Caves, a proposed newspaper strip Kirby developed in 1956.
To solve the Kamandi "problem," the folks at DC came up with an unusual solution: they
I never understood the desire for one consistent, streamlined version of future history. I mean, it's all fiction, after all! And as Yoda famously said, "Always in motion is the future." I'd prefer that the DC Comics present readers with dozens of potential futures - some utopian, some horrific, and some that are a little of both.
In the last few years, Kamandi has been worked back into the "mainstream" DC Universe. The Great Disaster is now said to have occurred in a parallel universe called Earth-51. It's better than nothing.
And, of course, Kamandi has teamed up with Batman in a couple of episodes of B&B, where we can see him back in all his Planet of the Apes-inspired glory.

Dear Michael Cera:
When you remake a movie that was originally released in 1946, you have to make changes. I get that. But did the makers of Notorious have to stray so far from the original film? In place of an espionage thriller with a twisted love triangle, we got a semi-historical account of the East Coast-West Coast hip-hop feud in the '90s. I say "semi-historical" because the filmmakers made the questionable decision to base all of the cast members on actual people, living and dead, who were involved in the hip-hop music scene at the time.
Smalls seems to be based on Alexander Sebastian, the villain played by Claude Rains in the original Notorious. I'm drawing this conclusion solely from the fact that Smalls' mother (Angela Bassett) gets a lot of screentime in the remake, and Sebastian lived with his mother in the original. Aside from that, Smalls seems to have absolutely nothing in common with Sebastian at all. I still have no clue as to which of the actors in the remake were supposed to be filling the roles of Cary Grant and Ingrid Bergman.
I'm sure that wouldn't have confused anybody.
Okay, he did make one decent movie, Guy Ritchie's RocknRolla in 2008. That's the one where Ritchie recovered his footing after his ordeal as Mr. Madonna. And by "footing," of course, I mean "testicles." But I digress.
Now Cage is broke, which means he's going to have to start building his fortune all over again. That means we can expect to see Cage in even more lousy paycheck movies in the years to come.
First of all, adult filmgoers were starving for an R-rated comedy. No studio seems to have the guts to make them anymore. In fact, most of the time, a studio will go out of its way to secure a "magic" PG-13 rating for a comedy. Speaking as an adult filmgoer, I think we're all getting a little sick of it.
I talked about Speedy quite a bit in
The Battling Bowmen were among a handful of World War II-era superheroes who survived through the '50s, though they never graduated from the back pages of books headlined by the likes of Superman and Batman.
Perhaps it's fitting, then, that when several of the Justice Leaguers' sidekicks got together as the Teen Titans in 1964, Speedy was also left out. He made a couple of guest appearances with the "Junior Justice League" (beginning, appropriately, with Teen Titans #4), but he didn't become a full-time member until 1969.
Still, Speedy made out a little better than Green Arrow in one sense. Filmation produced a series of animated shorts about the Teen Titans in the late '60s. At the time, the team's leader and most famous member, Robin, was unavailable, as he was appearing in the live-action Batman TV series. So Speedy filled in for him - beating his mentor to the small screen by several years.
Speedy was active with the Titans during most of the '70s, where he began an on-again, off-again relationship with his teammate, Wonder Girl. He also became a drummer for a rock band called Great Frog. But his most significant story arc during that decade came not in the Teen Titans' series, but in the pages of Green Lantern.
Pretty shocking stuff for a mainstream comic book in the early '70s. According to the story, Speedy felt abandoned by Green Arrow and drifted into the drug scene. Of course, he kicked his habit (perhaps a little too easily) and put his life back together, but his relationship with his former mentor has been strained ever since.
Somewhere along the way, Speedy knocked up the supervillain Cheshire. So Speedy may be the only mainstream superhero who both kicked a drug habit and fathered a child with one of the "opposition." He's currently raising his daughter, Lian, as a single father.
In the '70s and '80s, Speedy was generally written as an arrogant, womanizing hotshot. His portrayal in
Since then, he starred in his own mini-series, was involved with several more versions of the Titans (a superhero team that's proven about as stable as Courtney Love), and went through several costume changes.
In 2003, he put together a new team of
On television, Speedy made a few guest appearances in Cartoon Network's Teen Titans series and had a small role in one of the finest episodes of Justice League Unlimited, "Patriot Act," which turned into an impromptu reunion of the Seven Soldiers of Victory.
Being the jaded comic book reader I am, I've always thought Mia Dearden was just a stunt. I don't expect her to last very long. DC likes being able to point to her as "the superhero with HIV," but they'll probably kill her off in a few years before letting her get full-blown AIDS. The fact is, comic book fans don't want to read about AIDS. It's depressing. Comic book fans want to read about fictional diseases that can be miraculously cured (or un-cured) according to a writer's whim.
This sort of thing is what all-too-often passes for "character development" in modern superhero stories, which is one of the reasons I don't read very many new comic books anymore. What's even more pathetic is that the exact same thing happened to Green Arrow in two
