Editing Big Dumb Object (section)

==List of examples==
Big Dumb Objects often exhibit extreme or unusual properties, or a total absence of some expected properties:<ref>{{Cite journal|last=Palmer|first=Christopher|date=2006|title=Big Dumb Objects in Science Fiction: Sublimity, Banality, and Modernity|url=https://online.liverpooluniversitypress.co.uk/doi/abs/10.3828/extr.2006.47.1.10?journalCode=extr|journal=Extrapolation|language=en|volume=47|issue=1|pages=95–111|doi=10.3828/extr.2006.47.1.10|issn=0014-5483|url-access=subscription}}</ref>

* The monolith in Stanley Kubrick and [[Arthur C. Clarke]]'s 1968 film ''[[2001: A Space Odyssey]]'' (foreshadowed in the 1951 short story "[[The Sentinel (short story) |The Sentinel]]") is an indecipherable influence upon the protohumans, to whom it first appears. Later in the film, the monolith serves to show how little humans have evolved. The astronaut Bowman's attempt to interact with the monolith only makes him a part of its mystery.<ref>https://www.collativelearning.com/2001%20chapter%<nowiki/>{{Dead url|date=July 2024}}</ref>

* In [[Arthur C. Clarke]]'s 1973 novel ''[[Rendezvous with Rama]]'', a {{convert|50|km|mi|1|adj=mid|-long}} cylinder is detected entering the [[Solar System]]. A similar cylindrical probe of gargantuan dimensions threatens Earth in ''[[Star Trek IV: The Voyage Home]]''.

*The object discovered in ''[[Quatermass and the Pit]]'' was made of a material of extreme hardness, such that [[diamond]]-tipped drills and [[acetylene]] torches would not damage it. At the same time nothing would adhere to it.

* [[Charles Sheffield]]'s [[Heritage Universe]] setting features many immense alien artifacts, some of which are more inscrutable than others.

* The Marker from ''[[Dead Space (series)|Dead Space]]'' emits a persistent electromagnetic field from seemingly no source, which could be used to provide limitless energy. Attempting to reverse engineer the Marker, scientists discover that the electromagnetic fields generated by the Marker cause living people to suffer paranoia and hallucinations, while also causing the dead to reanimate, becoming "[[Necromorphs]]".

* In [[Sphere (1998 film)|the 1998 film]] based on [[Michael Crichton]]'s novel ''[[Sphere (novel)|Sphere]]'', the eponymous object would reflect everything in its presence except people. If it did reflect someone, they were alone, and the individual was accepted as worthy to harness the device's power.

* In [[Iain Banks]]'s novel ''[[Against a Dark Background]]'', the Lazy Guns have a lot of mass and yet little weight, and weigh three times as much upside-down as upright.
** By the same author, the titular [[Excession]] is a [[Black body|blackbody]] sphere that appears on the edge of Culture space and remains in position being inscrutable (even to Culture technology).

* The dome from the [[Stephen King]] [[Under the Dome (novel)|novel]] and [[Under the Dome (TV series)|television show]] ''Under the Dome'' is large and transparent unless touched by a person; it gives a slight electric shock when touched for the first time by someone, but not afterward. It cannot be penetrated, even by a [[MOAB]] bomb, and is seemingly causing many mysterious events in Chester's Mill, the town that the dome is enclosing, including causing all electronic devices near it to explode, visions, and, in one character, [[premature birth]]. 

* In Dan Simmons's 1989 novel ''[[Hyperion (Simmons novel)|Hyperion]]'', the mysterious Time Tombs, "huge brooding structures" which are moving backwards through time, and whose purpose, origin, and nature are not explained in the book, are the objective of the characters' pilgrimage.

Such unexpected properties are usually used to rule out conventional origins for the BDO and increase the sense of mystery, and even fear, for the characters interacting with it.
