[[quoteright:300:[[Webcomic/AwkwardZombie http://static.tvtropes.org/pmwiki/pub/images/Mass-Effect-as-Phlebotinum_6452.jpg]]]][-[[caption-width-right:300:"How could you HandWave everything like that?"\\

Some [[TheVerse settings]] ''have'' {{Phlebotinum}}. It helps [[ScrewTheRulesIHavePlot move along the plot]], HandWave various characters' [[WillingSuspensionOfDisbelief improbable]] powers, and conveniently get the {{Heroes}} [[TeleportersAndTransporters from point A to point B quickly]]. It can let you just say AWizardDidIt.

But then some settings...are different. They have nothing ''but'' Phlebotinum. That CityOfAdventure the heroes are exploring around? It's completely {{floating|Continent}} in the air; not one building is touching the ground. Why? Phlebotinum! In fact, the whole planet is probably bound together with some sort of magical or super-science energy, without which it would simply [[EarthShatteringKaboom explode]]. Every single thing around requires whatever the local flavor of Phlebotinum is to run in worlds such as these, whether it's [[FunctionalMagic magic]], {{nanomachines}}, TheForce, or something else similar.

The main dividing line between a world that simply has a lot of Phlebotinum and one that's [[MadeOfPhlebotinum made of the stuff]] is this litmus test: if you took away the Phlebotinum, would your world still exist in any meaningful sense, or would it more or less just [[TheEndOfTheWorldAsWeKnowIt collapse]]? If it would, your world is just plain Made Of Phlebotinum.

There is actually a great deal of evidence that ''RealLife'' is thus: when you develop a potent capability to the point that there are few side effects, you start using it for everything imaginable. When we learned to harness electricity easily, the only things weren't 100% electrical were the things that we used to generate electricity. When computers became advanced enough, we started carrying them around with us. Litmus Test? If you took away computers, it'd '''re-create TheGreatDepression'''. If you took away electricity, '''''ninety percent of the world would die within a decade'''''.

If something is literally made of Phlebotinum, see MadeOfMagic.


[[folder:Anime & Manga]]
* ''Manga/{{Bleach}}''. Everything in the Soul Society is made of [[{{Phlebotinum}} spirit particles]].
** So is everything in Hueco Mundo.
* ''Anime/TengenToppaGurrenLagann''. The world runs on Spiral Energy, quite literally the quintessence of determination, [[HotBlooded hot blood]], love, and willpower.
** As one commenter on Website/YouTube put it...
--->'''Youtube Commenter:''' I'm not sure which is weirder, the way the universe in this series works, or the fact that the universe works EXACTLY HOW KAMINA THINKS IT DOES!
*** Case in point: Kamina tries the whole CombiningMecha trope by literally smashing together the two parts of the Gurren Lagann. It actually works. Sort of.
*** Even weirder; the two mecha were never parts of each other before they were forcibly combined. There's only scant circumstantial evidence that the Lagann could be a modular attachment to a larger machine, but the attempt to merge it with a cobbled together Gurren caused obvious structural damage that pierced the cockpit, and narrowly avoided opening Kamina's skull to the sky.

[[folder:Comic Books]]
* In the early ''Tales of Suspense'' issues starred by ComicBook/IronMan, any and every technological innovation of Tony Stark was made possible thanks to "micro transistors." Even Iron Man's bulky iron armor could be ''folded like clothes'' thanks to the micro transistors. Almost every single one of Iron Man's tools was described with the adjective "transistor-powered" before its noun, from powerful magnets to incredibly fast roller skates.
** The Iron Man films do a similar thing with "repulsor technology". Initially the Jericho missiles are described as using "repulsor technology", which teases the later use of the technology as the foundation for the Iron Man suits. After Tony gets a "close up look at [the] old turbines" as Nick Fury puts it, the turbines on SHIELD's helicarrier are replaced with repulsors. An early version of the repsulor technology is teased in ''Captain America - The First Avenger'' with Howard Stark's flying car.

* In David Wingrove's Literature/ChungKuo, the world-spanning City is made of "Ice"
* ''Literature/{{Discworld}}'' can seem ordinary enough at first glance, until it's pointed out that, without heavy duty magic involved, a flat world on the back of a giant turtle that swims through space should be utterly impossible.
** The ''Science of Discworld'' books go on to give the Phlebotinum a name: narrativium, which (together with chelonium and elephantigen) in fact makes the formation of flat worlds on board giant turtles and elephants not only natural, but ''inevitable''. Too bad [[RealLife Roundworld]] lacks these ''perfectly normal elements'' and had to concoct some outlandish alternative involving big rocky balls...
** In ''Discworld/TheLastHero'' Discworld comic, Cohen and his Silver Horde have made it their mission to bring fire back to the gods --- via a large explosive. This would suddenly remove magic from the world and cause everything to die.
* The Roman-based society of ''Literature/CodexAlera'' is so connected with their Phlebotinum of Furycrafting that the use of certain techniques and technologies, such as quarrying, [[MedievalStasis are a lost art.]]
* ''Literature/TheChroniclesOfThomasCovenant.'' Then, in the Second Trilogy, [[spoiler:They lose the phlebotinum. This is way more horrific than it sounds. In part, because they eventually realize that the phlebotinum hasn't actually been lost: it's become corrupted and is causing the various disruptions that the world is experiencing (rainstorms, droughts, pestilences etc.)]]
* ''Literature/SixthColumn'' by Creator/RobertHeinlein is heading toward this in the end. The harnessing of magneto-gravitic, electro-gravitic and ternary fields promises to change the world even more than electromagnetism did and much faster. Everything TheResistance uses, both weaponized and mundane is based on those new discoveries.

* ''TabletopGame/{{Eberron}}'''s DungeonPunk world comes to mind as an especially obvious example of this trope. Without that magical-flavored {{Phlebotinum}}, everything in that world would fall apart ''hard''. It's pretty much MadeOfPhlebotinum.
** To a lesser extent, all ''TabletopGame/DungeonsAndDragons'' settings fit this trope. ''TabletopGame/{{Planescape}}'' and ''TabletopGame/{{Spelljammer}}'' especially, but even a place like ''ForgottenRealms'' is mildly MadeOfPhlebotinum.
** TabletopGame/{{Ravenloft}} literally so - it's a series of artifically-created "demiplanes" floating in the misty emptiness of the Ethereal Plane. When a domain's CosmicKeystone is destroyed, it may be absorbed by neighboring domains, or it may simply collapse into the Mists.
* ''TabletopGame/{{Exalted}}'', full stop. Creation itself is the greatest artifact ever built, while OddJobGods exist for individual rice grains and their interactions provide the physics of the universe.
** The Phlebotinum is named Essence, and it is [[ExactlyWhatItSaysOnTheTin the essence of everything ever.]] Even the unshaped raksha are made of it and use it to fuel their eldritch powers. Its name is used in many places where we would use the word "atom".
* ''TabletopGame/{{Numenera}}'' is set a billion years in the future, in the beginning of the Ninth World. As in, there were eight preceding great civilizations (very few of them human) that arose, mastered the Earth and beyond, hung around for thousands if not millions of years, and then collapsed or vanished. Now it's time for the ninth civilization to build itself up, mostly from the bits and pieces of phlebotinum left behind by the others. It's at the point where the whole world may technically be impregnated with or outright made out of [[{{Nanomachines}} smart matter]], which enables most "magic" in the setting.

* ''VideoGame/WorldOfWarcraft'' seems more MadeOfPhlebotinum than most fantasy worlds, what with all its [[{{Magitek}} magically-powered civilizations]] and such. What's also notable is the multitudes of flavors of {{Phlebotinum}}; The Draeni lean towards magic crystals [[ImportedAlienPhlebotinum given them by the Naaru]], [[OurElvesAreBetter Blood Elves]] throw around Arcane magic like it's going out of style, the [[OurGnomesAreWeirder Gnomes]] love their tech, with a healthy dose of Arcane, and the [[EverythingsBetterWithCows Tauren]] stick to their [[NatureHero hunting, gathering, and communion with nature]].
* In ''VideoGame/ChronoTrigger'', the magical floating continent of Zeal is this. It completely depends on magical energy to stay aloft and its residents do pretty much everything by magic.
* ''VideoGame/{{Touhou}}'' is pretty much supposed to be where, when TheMagicGoesAway on the rest of the Earth because [[MagicVersusScience the progress of technology leads to a lack of faith in magic]], all the magic is swept up and kept inside Gensokyo so that all the monsters, demons, and Gods can still live their magically supercharged lives. The technology is generally BambooTechnology hybrids with MagiTek, or simply stolen from "[[ThisIsReality the Real World]]". It is also worth noting that even the {{muggles}} have ''some'' kind of superpower in Gensokyo, it's just that you only hear about the [[ReallySevenHundredYearsOld world-bendingly powerful little girls.]]
* ''VideoGame/TalesOfSymphonia'' and ''VideoGame/TalesOfPhantasia'' are like this. The main focus for most of both games is preserving the mana flow and thus preventing the collapse of the world. Without it, magic won't work, crops won't grow, etc.
* ''Franchise/MassEffect'' uses this as its ''CharacterTitle [[TitleDrop Drop]]'', despite being one of the [[MohsScaleOfScienceFictionHardness hardest]] {{Space Opera}}s to date. How does [[CasualInterstellarTravel Casual]] FasterThanLightTravel work? [[AppliedPhlebotinum Mass Effect Fields]], generated by [[{{Unobtainium}} Element]] [[MinovskyPhysics Zero]]. How do the {{Flying Car}}s fly? Mass Effect Fields, generated by Element Zero. How do [[DifferentlyPoweredIndividual Biotics]] [[MindOverMatter move things with their minds]]? Mass Effect Fields, generated by Element Zero. How do the guns have BottomlessMagazines? Mass Effect Fields, generated by Element Zero[[note]] And computers in the gun which calculate the size of the shot needed and shave it off of a large block inside the weapon.[[/note]]. How do [[spoiler:the Reapers build a space station in the '''[[UsefulNotes/BlackHoles galactic core?]]''']] '''''[[OverlyLongGag Mass Effect Fields, generated by Element Zero.]]''''' And of course, without Mass Effect Fields, generated by Element Zero, [[AnthropicPrinciple there would be no interstellar civilization]].
** [[http://masseffect.wikia.com/wiki/Dark_energy It's still pretty hard]], [[http://en.wikipedia.org/wiki/Dark_energy all things considered]].
** The consistency of this trope throughout the series is one of the reasons the [[spoiler:Synthesis]] ending of ''VideoGame/MassEffect3'' was considered so terrible. It had nothing to do with the mass effect fields. Nor was it generated by element zero.

* In the blog-novel ''Literature/FlyoverCity!'' – Malphysical Particles create a cosmic loophole which render the laws of physics “malleable”, allowing the story’s superheroes to do all those superhero-y things that are impossible in the real world.
* The world of ''Literature/TalesOfMU'' is driven by {{Magitek}}, the physics are based on AWizardDidIt, and from the point of view of people in other worlds, a knife that was said to be "barely enchanted" is ''[[MadeOfMagic made out of magic]]''.
* Literature/{{Elcenia}}, [[http://elcenia.com/11/251-2-41.shtml here]]:
-->"Physical laws? Oh, those things. We don't have them."\\
"But everyone has them. It's a fundamental principle."\\
"Not in this world. Everything is taken care of by magic in various forms. What's holding you to your seat isn't gravity, for example."\\
"Oh, what then?"\\
"Magic. Don't look so alarmed. It's at least as reliable as gravity is."

* The four fundamental forces of the universe. We know ''how'' they work; the ''why'' on the other hand would need a theory of everything (Or at least this universe).
** The fact that everything is made out of ''matter'' is a bit of a headscratcher in itself. Matter and antimatter must have been made in equal quantities in the big bang, so why didn't they just annihilate each other?
* Life. Its all over the place, but we don't really have any concrete ideas about where it came from or how it started, and haven't had much luck finding it anywhere else so far.
