History Main / UnrealisticBlackHole

* ''VideoGame/SuperMarioGalaxy''. [[spoiler:Bowser's plans go bust, one of his stars collapses and turns into a black hole, universe gets sucked in? Disregarding the fact that it's actually possible to ''fight inside'' said star without dying painfully, black holes... just don't work that way.]]
** The black holes that function as bottomless pits for each level. There are only two realistic things to them: they suck and they red-shift.
** In the [[VideoGame/SuperMarioGalaxy2 sequel]], Bowser somehow manages to top himself by [[spoiler:roaring a black hole to existence for the final battle. After taking enough punishment, he admits defeat and is swallowed by the black hole, closing it]]. Not to worry, though, [[spoiler:Bowser shows up again in the credits, and he's ''tiny!'' (and ''mad!'')]]
** Before that, in Bowser Jr's third fortress [[FridgeLogic he managed to build a structure with one in the center]].
* The Void from ''VideoGame/SuperPaperMario'' is somewhat of a subversion: It eventually sucks up everything in the multiverse. Black holes aren't interdimensional, and they aren't cosmic vacuums; they just suck up anything that's too close. Also, [[spoiler:there's a castle in it]].

** For bonus points, the weapon appears again as the "Rift Inducer 5000" in ''VideoGame/RatchetAndClankFutureACrackInTime'', though this time the black hole contains an EldritchAbomination with CombatTentacles named [[FluffyTheTerrible "Fred"]], who [[BreadEggsMilkSquick "enjoys moonlight strolls along the beach, reading and mauling on suspecting enemies with brutal efficiency."]] When upgraded into the Rift Ripper 5000, the black hole ''explodes'' due to the manufacturers "removing the horetzion stabilizer". RuleOfCool and RuleOfFun are in full effect here.

* ''{{Film/Zathura}}'' has a {{justified|Trope}} example. [[spoiler: The titular Zathura is a black hole used as a reset button, and sucks up everything created by the game as the players kept on. It's justified because it's not a real black hole, but a creation of the magical board game.]]

* ''ComicStrip/StarFox'': A black hole was created when Andross sabotaged the device Fox McCloud Sr. was taking into the Asteroid Belt. The Black Hole sucked in fully a third of the Asteroid Belt, and remained in interplanetary space. Unlike real black holes, this one was fully visible as a purplish maelstrom in outer space, and it functions more-or-less as a Warp Zone to other locations in the Lylat system.

... Unless it's fiction. Sometimes they just suck in everything around them like giant [[SpaceX space-vacuum-cleaners]], seeing as GravitySucks. This can range from whole planets to just the BigBad of the story (and in those cases, the black hole conveniently closes after swallowing him). Also commonly, a black hole will be represented as an actual hole in space and it will be perfectly possible to enter a black hole and leave it safely. Sometimes a black hole will be completely flat, apparently forgetting that our universe is 3D. [[YearInsideHourOutside Relativistic time dilation]] tends to be ignored; a character voyaging into a black hole can leave it without time warping, while those outside can see things enter a black hole without slowing to a crawl.[[note]]To an external observer, anyone or anything entering the event horizon would cease moving, then slowly fade away, as the last of the light reflecting off them either dissipates or is sucked in as well.[[/note]] Hovering black holes are often seen as weapons. Also, if a black hole forms during the story, expect its gravitational pull to instantly skyrocket instead of remaining the same as the pull of the star that collapsed to form it. Of course it will be completely insane for anything to be orbiting it, despite the fact that we are orbiting a black hole right now.

Even orbiting a black hole wouldn't be a safe place for organic lifeforms, as you would be constantly pelted with orbiting dust and debris flying at ludicrous speeds, all while simultaneously being cooked alive and having your DNA melted by the incredible temperatures and intense emissions of radiation, including X-rays and Gamma rays. Needless to say, black holes are pretty scary things. Scary, yet deeply fascinating and mystifying things.

* Gildarts from ''Manga/FairyTail'' actually ''crushed'' a black hole that Bluenote brought into existence. Justified in that Gildarts, Bluenote, and all major characters are [[AWizardDidIt magic users]] and Gildarts specific magic "Crush" is quite literally defined as the ability to destroy ''anything'', particularly other magic spells.
* ''Manga/Reborn2004'' has Kozato Enma, who can create stars and black holes at will as part of his [[GravityMaster Earth Flames]]. [[TheHero Tsuna]] can still fly past the black holes ''and'' blow it up. In addition, the black holes never affect anyone not involved in the fight; observers can stay in the same room as one and not be spaghettified; if the series used realistic black holes the whole planet Earth would be as dead as it's possible to get the instant one showed up.

* The ''Anime/SailorMoon'' Super S movie had the titular black dream hole. Which was spherical. And the inside was apparently made of webbing.

Note that for decades, the exact appearance of a black hole was solely a theoretical and artistic undertaking, constantly changing and shifting in line with the emergence of new scientific theories and shifting schools of thought. On April 10, 2019, [[https://news.virginia.edu/sites/default/files/styles/uva_basic_article/public/article_image/black_hole_eht_collaboration_header_3-2.jpg?itok=QswyneRQ the first ever image of a black hole]] was released to the public. It was undertaken by the Event Horizon Telescope and a globally collaborative scientific undertaking by multiple universities across the world.

* ''Film/EventHorizon''. The titular spacecraft featured and the "[[FanNickname Hell-Drive]]". It used an ''artificial black hole" to do a gravity-based spacewarp that apparently takes you straight through the [[TabletopGame/{{Warhammer 40000}} Warp]]. Touching the black hole, rather than tearing you to atoms, gets your hand stuck in "black hole goo", then pulls you bodily in before (somehow) spitting you back out (though the designer of the engine explicitly states it shouldn't have opened or been able to do that [[spoiler:but hey, that's what happens when your ship turns into an EldritchAbomination]]).

UsefulNotes/{{Black holes}}. They're the most terrifying things in the known universe. They're huge masses of... well, ''nothing'' (but they do have a lot of [[ShapedLikeItself mass]]); and [[PowerOfTheVoid nothing, not even light, can travel fast enough to escape them]].[[note]]A black hole is any object which has an escape velocity that is greater than the speed of light. The event horizon (or [[NamesToRunAwayFromReallyFast Schwarzschild radius]]) is the boundary within which this condition is met.[[/note]] Unfortunate items which do fall in are [[https://en.wikipedia.org/wiki/Spaghettification spaghettified]] (the official scientific term), stretched thin by [[http://en.wikipedia.org/wiki/Tidal_force tidal forces,]] the black hole ripping atom from atom, then [[DeaderThanDead ripping up the atoms]]. But that's only if you get too close. From far away enough, in a stable orbit, being near a black hole would just be the same as orbiting a massive, [[StealthInSpace invisible]][[note]] The [[ShadowDiscretionShot gravitational lensing effect]] is hard to overlook so the black hole would appear as a silhouette against the stars — see the Other Wiki for a simulation thereof. And then Hawking's radiation would actually make the thing pretty bright.[[/note]] star, only the black hole would be much smaller.[[note]]For a nice size comparison, see [[https://youtu.be/QgNDao7m41M this video.]][[/note]] For example, if the sun were to suddenly be magically converted into a black hole of the same mass, the earth's orbit would continue on exactly as before, completely unaffected (gravitationally, that is — the lack of heat and light would, of course, rapidly end almost all life).

* Patrick Moore's ''Scott Saunders Space Adventure'' novels are generally on the harder side of [[MohsScaleOfScienceFictionHardness the sci-fi scale]]. However, in the novel ''Secret of the Black Hole'' the eponymous artificial black hole was at one point described as being "at most an inch" in diameter. A black hole of such size would have greater mass than Earth, yet the hole was still orbiting the Earth, rather than vice versa. The novel was written in the 1970s, when black holes were even less well understood than now.

* ''VideoGame/SuperMarioGalaxy''. [[spoiler:Bowser's plans go bust, one of his stars collapses and turns into a black hole, universe gets sucked in? Disregarding the fact that it's actually possible to ''fight inside'' said star without dying painfully, black holes... just don't work that way.]] The reason no one thought of this while playing the game was the fact that it's ''[[RuleOfCool completely freaking awesome]]''.

** In ''WesternAnimation/TransformersGeneration1'', a black hole sucks in two ships: one that the good guys and bad guys are on, and one to get sucked in before it just to [[TheWorfEffect show us the threat is real]]. That other ship went 'kaboom' before entering. There's plenty of "Oh, noes, we're gonna get squishificated!" talk. And then they go in and... wind up in a color-inverted universe. And rather easily escape.

* ''ComicBook/{{Sleeper}}'' shows us a "A suitcase black-hole bomb".

* In an old ''ComicBook/{{Firestorm}}'' comic, a giant named Brimstone is trapped in the center of the sun, and his presence creates a black hole. Firestorm, at this point Dr. Martin Stein a lone fire elemental, closes the black hole by shoving Brimstone through it, but gets sucked up himself. He winds up emerging from a White Hole in a parallel universe, and resolves to spend his time exploring the place. Comics, everybody!

* [[https://sites.google.com/site/largenumbers/home/2-1/microcosm this site]] calculates that the smallest object possible (based on current knowledge) is a black hole with the mass of a neutrino, the least massive baryon (non-massless particle) known, which would have a schwartzchild radius of about 10^63 meters. The reason it's unrealistic is the Plack Length (about 10^35 meters) is currently thought to be the [[ArbitraryMinimumRange smallest length possible,]] although [[ScienceMarchesOn improvements on quantum theory]] may solve this problem.
