** In a recent patch they tried to make it slightly more realistic by having enemies rotate around the center.

* The ''Series/DoctorWho'' episode "The Impossible Planet" features a planet in a stable orbit around a black hole; in the show the orbit is only maintained due to the expenditure of great amounts of energy to cancel out the gravity of the black hole. In reality, objects can orbit black holes just as easily as they can orbit any other massive object (our entire galaxy orbits one). That said, the episode ''actually'' seems to depict a planet that's maintaining a stable orbit within a black hole's event horizon without actually describing it as such. This ''should'' indeed be impossible without some fairly fancy tricks that are beyond physics as we understand it. That said, if that were true, it's hard to see how anyone could have found out about it in the first place, as anything within a black hole's event horizon should be completely invisible.

Although the planet is generating a "gravity corridor" which allows for safe ship landing, so it's quite possible that someone discovered that and followed it through.

** In a non-destructive example, ''VideoGame/RatchetAndClankFutureACrackInTime'' has the duo taking a "shortcut" through one to escape a band of [[SpacePirate space pirates]].

* Played for laughs in ''WesternAnimation/RexTheRunt''. The gang manage to pilot the entire Earth (which they punctured) into a black hole (which makes [[SpaceIsNoisy bathroom plughole gurgling noises]]), and find only a rather drab cafeteria at the centre. They call a cab to get them back home again.

* ''VideoGame/KingdomHearts'' Averts this with the DefinitelyFinalDungeon, which looks exactly how a Black Hole should look. It's very fitting considering the nature of the world...

* ''VideoGame/SaintsRowIV'' has the Black Hole Launcher (aka the "Singularity Gun") with significantly reduced effectiveness than what a real black hole launcher would have, for gameplay purposes of course.

* ''VideoGame/DefenseOfTheAncients'' and ''VideoGame/Dota2'' has Enigma, whose ultimate ability, 'Black Hole', summons a vortex that hovers above the ground, sucking in every enemy (but not allies or terrain) in a very small area until it disappears or Enigma stops channeling. [[GameplayandStorySegregation Lore wise it is described as having the power to end worlds.]]

* In [[Series/TheFlash2014 the 2014 live-action adaptation of the Flash,]] the Season 1 finale ends with [[spoiler: Barry destroying a tiny black hole that threatened to consume the city by ''running around the accretion disk''.]] Needless to say, this is not a strategy one should attempt or expect to work on actual black holes.

*** The more massive a black hole is, the SMALLER the tidal forces immediately next to its Event Horizon. This is because the tidal force isn't literally the gravitational pull of the black hole in a position, but rather the DIFFERENCE in pull between two ends of an object. The gravitational force is directly proportional to the product of the mass of the object and the mass of subject and inversely proportional to the distance between two objects when neither is overlapping the other (since the actual black hole is infinitely small, you can get infinitely close without overlapping it); therefore, a black hole with an Event Horizon only three meters across will have an absolutely massive tidal force at its event horizon (if a person is 1.5 meters tall, your feet feel over three times the force your head does, so it feels like you're being torn to shreds since even a small black hole has an obscene force of gravitation), while one the size of Neptune's orbit would have a negligible one - you could be inside the event horizon and suffer no noticeable tidal force for quite a long while, although you'd also be dead.

*** Black holes may not be luminous, but the accretion discs that tend to orbit them (like the one in the movie) are. Black hole accretion discs tend to give off lethal amounts of gamma and hard X-ray radiation though, so any planets orbiting their host black holes would be completely uninhabitable.

*** Accretion disc around black holes ''do'', however, tend to give off radiation. Planets around them would still be uninhabitable though, since radiation would include lots of gamma and hard X-rays.
