Planet killer

From Wikipedia, the free encyclopedia

In science fiction, a planet killer (also called a "planet buster" in some Sci-Fi circles) is an entity, often a large spaceship or space station, expressly designed to destroy or render uninhabitable a planet. The most famous planet killer is the Death Star from the Star Wars franchise, though many others have been seen on film or print. The science fiction series Babylon 5, Star Trek, Lexx, Farscape, and Stargate SG-1, the tabletop game Warhammer 40,000, as well as the Starflight and Wing Commander computer games all have at least one such device.

The Star Wars Expanded Universe uses the term "superweapon" for such a device.

[edit] To Kill a Planet

Science-fiction writers have devised many methods of destroying a planet; blasting it with a specially designed laser weapon, launching nuclear missiles at the surface until the radiation and heat sterilizes the planet, or through the use of exotic energy weapons not covered by present-day physics. The defining criterion is that the weapon must at least destroy the planet's entire ecosystem and render the planet uninhabitable afterwards; a more thorough tactic is to physically demolish the planet itself. Genre writers, being ever-creative to one-up each other's worst atrocity machines, have created many designs to fulfil both of these purposes.

Most writers, working in a print medium and unable to match the visceral chill of a short film sequence of an obviously life-bearing blue marble world being turned into a brilliant fireball in less than a second, prefer to use slower methods of planet destruction, making up in pathos what they lack in instantaneous impact. Under such a constraint, planet destructions are often much slower affairs, taking minutes, hours, sometimes even days for the protagonists to act or simply reflect upon their fate. The classic exception to this rule is probably Douglas Adams's The Hitchhiker's Guide to the Galaxy, the print version of which destroys the Earth in three sentences:

There was a terrible ghastly silence.

There was a terrible ghastly noise.

There was a terrible ghastly silence.

When categorizing such apocalyptic instruments, one should note that several devices – Asimov's Electron Pump or the 27th century Tox Uthat, to name a couple – operate not by destroying a planet, but by annihilating the star which it orbits. The absolute energies involved here can exceed that produced by the Death Star's blast, but they are generated indirectly. Finally, inventions like Egan's Ensemble mod are too esoteric to admit classification by energy output.

[edit] To Eat a Planet

Some writers (and comic book cartoonists) make stories about devices that convert planets into various products, often other machines (although the Monoliths in 2010: Odyssey Two turn Jupiter into a star). In the cult science fiction television series Lexx, the main characters pilot the eponymous Lexx battleship, "the most powerful destructive force in the two universes,” which first blows up planets with a powerful blast of energy, and then consumes the mass for fuel. The Doomsday Machine from Star Trek functions similarly.

More literal examples of eating a planet are seen in the 3D series Shadow Raiders, in which the Beast Planet (the main threat of the protagonists) is a virtually indestructible ball of black steel which can open to reveal a claw which pulls hapless worlds into its grasp, and in the various incarnations of Unicron in the Transformers multiverse. The comic book villain Galactus falls somewhere between the two foregoing categories, consuming - but not necessarily physically eating planets.

An even more extreme example in this category could be the Star Wars' World Devastators, horrifying, nigh-indestructible weapons that literally eat through a planet, consuming all elements within to create massive mechanized armies within its hold, or with sufficient raw material and time-another World Devastator.

These were destroyed by pitting them against the only foe that could defeat them-themselves.

The Tyranids of Warhammer 40K are similar to these, but merely devour all of the biomass of the planet, not the planet itself. Using several stages of infiltration, invasion, and consumption, Tyranid Hive Fleets scour all biological matter from the surface of a living world, leaving it no more than a cold rocky ball in space.

[edit] To Blow a Planet Up

In order to completely disperse a planet, one must supply at the very least enough energy to overcome its gravitational binding energy. One can supply more than this, of course, to overcome inefficiencies or to make the planet's dispersion more spectacular. The king of brute-force planet destruction is the Death Star, whose energy output has been estimated to equal "the liberated energy of a small artificial sun" (STAR WARS novelization). Then again, the Veloxi Black Egg from Starflight could do the same thing in a package about fourteen quintillionths of the volume and mass, so in terms of power per mass the popular king may be relatively lacking. In The Forge of God, Greg Bear estimates it may take some two hundred million tons of matter converted to energy at the core of an Earth-sized planet in order to give its mass enough energy to achieve mutual escape velocity (where a large nuclear bomb may only convert a few grams of matter to energy.) Clearly this suggests interesting technology in doomsday ships whose mass is only a tiny fraction of that.

A weapon of this type is often referred to, in SciFi circles, as a "Planet Cracker," a term first coined by Diane Duane.

[edit] To Render a Planet Uninhabitable

For many plot purposes, it is sufficient to render a planet uninhabitable instead of completely destroying it. There are countless ways of accomplishing this, as it is usually enough to disrupt only one of the requirements for life. As examples, in Larry Niven's Known Space, the planet of the Grogs (a race who could exert mind-control) had a Bussard ramjet in orbit around the star. If necessary, it would fly into the star, and the ramjet "scoop" would disrupt the stellar magnetosphere, causing long term problems that would eventually end life on the planet. A more direct method of planetary extermination occurred in Catherine Asaro's Primary Inversion. Here, some of the atmosphere from a gas giant was siphoned onto the air of the planet, and its atmosphere was lit on fire. Anyone who could withstand the searing heat and following torrential downpour would find no oxygen left to breathe. In the comedy movie Spaceballs, the title species plots to steal all the air from the peaceful planet of Druidia. This plot is subsequently foiled by a Luke Skywalker/Han Solo type hero with help from a Chewbaka-like character(Barf). Ben Jeapes' novel The Xenocide Mission, the superweapon "Device Ultimate" is a series of boxes containing a device that is placed in a small spacecraft and fired into a sun. This would cause the sun to become unstable, exploding the first 1% of the sun, and releasing enough radiation to kill all life in the solar system, as well as disintegrating the first planet of the solar system. In Peter Hamilton's novel "Judas Unchained", the Prime Aliens use a device which induces a directed, high-intensity long-duration solar flare, which literally fries the surface of a planet. In addition to the Death Star from the Star Wars series, the Eclipse class Super Star Destroyer has a superlaser that, while not capable of completely destroying a planet like the Death Star, can crack the crust of planet to make it uninhabitable.

Less large scale efforts at making a planet uninhabitable include chemical, biological, and nuclear attack, as well as dusting the surface with radioactive dust (as in some of Isaac Asimov's short stories). In Kurt Vonnegut's Cat's Cradle, the author also presents a version of water called "Ice 9" which is just like ordinary water except that it takes on a crystal form at room temperature. Ice 9 can also convert neighbouring water molecules from their "wet" form into their crystalline form (in a similar way that some prions can influence other proteins by making them fold into different shapes, with the new shape also having this property). The result of contaminating even the smallest part of the water system on a planet like Earth would have disastrous consequences for all the liquid water on the entire planet, as effectively there is really only one body of water which is connected by rivers, seas, drains, groundwater reservoirs, and so on. A single chip of Ice-9 would be capable of rendering a planet uninhabitable to water-needing life such as just about every living thing on Earth. In Warhammer 40,000, a planet can be destroyed by a process called Exterminatus, in which a fleet's payload of one of 2 kinds of bombs is dropped onto the planets surface. Either Virus bombs, which unleash diseases that kill off everything and linger, or Cyclonic torpedoes, which ignite the planet's atmosphere. Very rarely are both used on one planet, but this was the case during the destruction of Isvaan III. Another example of this is shown in the Halo novels, in which the Covenant are shown "glassing" Reach, in other words, bombarding it with so much plasma that the surface actually melted and recooled into glass, rendering all life vaporized and the planet useless.

A gate positioned in the surface of a sun dialed P3w-451, causing matter to be sucked through the gate in sufficient quantity that the star was destabilised and went nova. Presumably dialing from a planet bound gate would destroy that planet.
• The Replicators have eaten an entire planet and covered everything on it into replicator blocks.

"Doc" Smith's Lensman saga: "super-atomic bombs"; a "nutcracker", consisting of crushing a planet between two others; a "negasphere," an antimatter planet; "Nth space planets" from other dimensions can be used to ram planets or even create supernovas - there was even the worrying possibility that these could cause the Big Crunch in zero time; and a "sunbeam", a way of concentrating most of a sun's energy output into a narrow beam -- this one a defensive-only weapon against nutcrackers and negaspheres.
• In E. E. Smith's Skylark of Space series various planet-killers are used or discussed. Throwing planets and moons out of orbit, incredibly high-yield atomic or copper bombs, near-instantaneous dematerialisation of physical objects and the teleporting of close to fifty billion stars in order to wipe out a Galaxy-wide alien civilisation are all used.
