Wormholes Are Blue

The tendency for wormholes to be blue

Simply put, in a lot of fiction wormholes are coloured bright blue or bright blue with some white. There are several possible reasons:

  • A possible reason for this is because wormholes are inspired by black holes, and they use the color blue in place of black. That and if they were black in space you wouldn't be able to see it.
  • Cherenkov radiation (which is blue) is often associated with FTL and thus wormholes in fiction.
  • Blue (or actually slightly into 'near ultraviolet') is the highest frequency (shortest wavelength) light we can see (another reason why it's used).

NOTE: what wormholes really should look like is just a hole in space with someplace else on the other side.

See also Our Wormholes Are Different, Swirly Energy Thingy.


Examples:

Documentary
  • In the TV version of The Elegant Universe, wormholes are depicted as a whirling kaleidoscope of blue and orange. A rather egregious error, given that this was supposed to be an educational program about spacetime and should have known how to depict them properly.

Film
  • The Stargate movie creates a blue wormhole.
  • Hyperspace in Star Wars looks like a blue-walled tunnel.

Live-Action TV
  • Many of the Wormholes in Star Trek are blue, though not all.
  • Stargate SG-1's wormholes are blue.
    • Also the gate apertures in all versions looked like a rippling blue pool of water.
  • Farscape wormholes seem to be blue as well.
  • The Slipstream from Andromeda.
  • Babylon 5:
    • Entering into hyperspace is blue (some times yellow) even if Hyperspace it self is like red nebula.
    • It was specifically incoming jump points (from hyperspace to normal space) that were blue and outgoing points that were orange.
  • On Doctor Who (especially in the opening titles) the time/space thingy they travel through is represtented as a blue-walled tunnel.
  • The portals in the show Sliders were often blue. The heroes' wormhole was usually blue or white and the timers of enemeies usually produced red or orange wormholes.
  • Played with in The Big Bang Theory. Sheldon pranks Raj and Howard for planting a camera in a room he uses to relax to see what he does in there. He uses the camera to film himeself and edited in a fake wormhole generator test, with a light blue wormhole, complete with a Face Hugger that attacks him when he looks inside.

Play-by-Post Games
  • The Einstein-Rosen bridge in Darwin's Soldiers is specifically mentioned to be blue.

Video Game
  • The Town Portals from the Diablo series.
  • Frontier: Elite II has wormholes created by ships' hyperdrives that are blue on the way in and red on the way out.
  • The time gates in Chrono Trigger.
  • Let us not forget the wormholes in Spore.
  • FreeSpace subspace is also blue.
  • The Jump Gates and Jump Holes from Freelancer are send you through a white-and-blue tunnel. Of course, Freelancer had to give their wormholes some kind of interior since they also acted as loading screens.
  • The Hypergates in Escape Velocity Nova creates a blue Swirly Energy Thingy when they open.
  • Gruntz has blue wormholes that appear during the intro and outro and when gruntz enter and leave a level. There are also generic blue wormholes that can be used by a single grunt before disappearing - their function is to teleport the grunt to a different part of the level. As a subversion, there are also green wormholes (reusable) and red ones (hidden, appearing for a short period of time) that do the same thing.

Western Animation
  • Wakfu: Yugo can create portals that are light blue, and there are teleporter gates called "zaaps" that are also light blue. Most of time he can only travel short distances, or to other cities via zaap. But on a couple of occasions in the second season his portals have taken him to other dimensions.

Unsorted
  • When Siskel and Ebert reviewed The Black Hole (1979), they specifically commented about how the "black" hole was actually blue.
  • The 1981 pinball game Black Hole seems to have an predominantly blue color scheme.

    Is there a reason for this? Patterns can be tropes, but there needs to be more than just a broad coincidence.

    I can't be sure and I'd love insights into why... a part of me thinks there may be a reason its become iconic, another part of me suspects it may have something to do with the concept that 'wormholes are powerful but helpful', meaning they get the 'good guy colour' blue.

    But without sources or other opinions to back that up its hard to know...

    I think this has more to do with the general blue-ing that has been going on with sf movies.
  • July 28, 2012
    Twilord
    Sci-Fi Movies?

    I notice it alot more in the TV-Shows.

    Might actually be something to do with the colour being popular for modern computers? Therefore high-tech? Therefore advanced and alien? I might be wrong.

    two-colored (e.g. blue and red or green and red) portals are at least as widespread
  • July 29, 2012
    MattStriker
    Blue and red are classic colors due to the phenomenon of blue-(or red-)shifting. I have no idea what exactly would go on around the interface of a wormhole, but it's fairly likely that it'd do strange things to light passing through, and color-shifting is probably among the more visible.
  • July 29, 2012

    Probably what you're seeing is black or indigo, with light spectrum passing through it. So yea, it might look like blue in Real Life. Only, I'm no scientist, and haven't gone close enough to find out.

    It could be more like Hypespace Is Blue.

    Babylon 5 entering into hyperspace is blue (some times yellow) even if Hyperspace it self is like red nebula.

    Freepace subspace is also blue.

    Wing Commander equivalent is more green.

    I believe you may actually have a very good point there Death Cloud; now that I think of it regular hyperspace is also blue in the Stargate-Verse...

    Twilord, I could be mistaken, but aren't the Hyperspace tunnels in Stargate more of a purple-white? At least, they were in the beginning.

    • [[Video Game/Elite Frontier: Elite II]] has wormholes created by ships' hyperdrives that are blue on the way in and red on the way out.

    @Death Cloud: I think it's more frequently wormholes, but wormhole in this context could refer to any tunnel-like passageway with a vortex-like aperture.

    @Matt Striker: That was the explanation given by J. Michael Strasynski (however you spell his name) for the orange and blue entrances and exits from hyperspace in B5- hyperspace was a dimension where faster-than-light travel was possible, and material exiting hyperspace was blue-shifted, whereas material entering hyperspace was red-shifted. Or it might have been the other way around.

    @randomsurfer -- the Tardis tunnel it's blue when travelling back in time, red when travelling forward....

    The color of the portal depended on whose timer they were using.

    re: The Elegant Universe

    given that even if these may exist for real (which is less than certain, to put it mildly), there aren't any observed - what's the difference?.. Either way it's going to be a cute picture illustrating speculative pop-science.

    StargateSG-1's wormholes are blue - but in Stargate Atlantis they're green, the one in Stargate Continuum kinda went kaliedoscopic, and I forget what color they were in Stargate Universe but it wasn't blue...

    Do black holes count? When Siskel and Ebert reviewed The Black Hole (1979), they specifically commented about how the "black" hole was actually blue. And for what it's worth, the 1981 pinball game Black Hole seems to have an predominantly blue color scheme. http://www.ipdb.org/showpic.pl?id=307&picno=6021

    I'd assume the reason for this is because wormholes are inspired by black holes, and they use the color blue in place of black. That and if they were black in space you wouldn't be able to see it.

  • September 9, 2013

    ^It's probably like that as just a style choice, not because of high or low frequency. I can think of several equally likely reasons to choose that color just off the top of my head.

    also to quote (possibly out of context) Fast Eddie:
    Not another %$&^%&^ color thing, please. This wiki is about storytelling tropes, not mostly coincidental things that happen to repeat.

    And given we have examples that go "Many of the Wormholes are blue, though not all". I'd say this is People Sit On Chairs. Unless there's somehow a meaning to this?
