History Main / UnrealisticBlackhole

... 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 is then red-shifted to invisibility over a long period of time.[[/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.

A subtrope of SpaceIsMagic — indeed, if the canon in question has magic then that's your HandWave for getting away with this trope. For two similar, more terrestrial examples, see DoNotTouchTheFunnelCloud and QuicksandSucks; in the case of the latter, it too is often depicted as actively suctioning things into itself, when in reality the pulling power of both works around the force of gravity instead. When the black hole is used as a method of travel, see OurWormholesAreDifferent. Very commonly used as a NegativeSpaceWedgie. Often involved in a SpaceshipSlingshotStunt.

* One memorable [[ComicBook/DisneyDucksComicUniverse Italian Disney story]], which was pretty crazy even by comic book standards, had Scrooge attempt to solve the waste management crisis by dumping garbage into a black hole. He has all the world's garbage accumulated in a single landfill, to be loaded into a massive rocket... but the combined weight destabilizes the Earth's orbit and sends the planet spiraling into interstellar depths and straight for the black hole. The garbage rocket (which is powered by gold for some reason - you could say they achieved [[Main/JustForPun gold fusion]]) is chained to the earth and launched as a counter-pull against gravity. The rocket pulls the planet when it's just fallen halfway into the black hole, but all it can do is keep it from falling further in. [[SarcasmMode Does it not have enough power to counter a measly black hole]]? Oh, that's not the reason. It gets weirder. Scrooge and nephews explore the other side of the hole, and find that it's a parallel universe where the alternate Scrooge ''also'' attempted the garbage rocket plan, ''also'' ended up falling into the same black hole, and the alternate Earthlings are now ''also pulling from the other side with their own rocket with the exact same force.'' The situation is eventually solved when Scrooge and his alternate counterpart sacrifice the very last of their gold, which gives the two rockets enough power to pull both planets out, intact, simultaneously.

* In ''VideoGame/{{Noita}}'', the Black Hole spell launches a projectile that erases all terrain, but does not directly affect living creatures in any way.

* The ''WesternAnimation/JusticeLeagueUnlimited'' episode "[[Recap/JusticeLeagueUnlimitedS1E7TheGreatestStoryNeverTold The Greatest Story Never Told]]" has a scientist who grows a black hole in his stomach. By the end of the episode, Booster Gold is able to release everything that had been sucked in, completely unharmed.

* One episode of the ''WesternAnimation/SuperFriends'' had Wonder Woman, Hawkman and Black Vulcan trapped on an artificial play world built by The Toyman in the center of a black hole (no, they don't explain how he was able to do this). Aside from not being able to escape the black hole the heroes walk, run, jump and otherwise move perfectly fine. At the end Superman and Green Lantern fuse into one being to tear a hole in the black hole and allow the others to escape.
