A Displacer is a space teleportation device. They were used to transport matter - lifeforms, cargo, and ordnance - from one point in real or hyperspace to another for practically any purpose.

Displacements were also called dislocs within the Gizilt civlization.[1]


Displacer units are available in a range of sizes and capabilities.

In the 22nd century CE, a unit capable of moving a microscopic object 14 metres could be fitted into a Chelgrian Soulkeeper.[2]

Units aboard a Culture GSV in the 19th century could move small spacecraft within a star system.[3]

"Heavy-duty" units, as carried on Culture spacecraft, were better able to handle emergency snap-Displacements.[4][5]

Very large units could move Culture Gangster-class Offensive Unit-sized objects a short distance.[6]

Generally, the capability of a unit increased with its size or mass.[3]


The volume - and its contents - to be Displaced was encapsulated within a containment field.[7] The field was moved through hyperspace, where it took the form of a singularity.[4] The singularity could be intercepted and it contents separated and redirected; this was not a widely known Culture capability even within the Culture in c. 29th century CE.[7]

The arrival of a Displaced volume appeared initially as a tiny point of blinking light, which rapidly expanded into a grey or silvery sphere that subsequently disappeared to leave the volume behind.[3][8] The intensity of sound caused by the departure and arrival of a volume depended on the speed of the Displacement.[9][10][8]

Displacers could accurately deliver chemicals and other substances into a biological body for medicinal or recreational purposes.[11][10]

The power needed for a Displacement increased as distance and mass increased.[2]


The uncertainty principle applied to Displacement singularities in hyperspace, creating a non-zero probability of catastrophic Displacement failure, invariably leading to the death of a Displaced lifeform.[4]

The catastrophic failure rate of Culture Displacements was put as 1 in 80 million in the 19th century CE,[3] 1 in 83 million in the 21st century CE,[4] and 1 in 61 million in the 22nd century CE.[12] Some Culture machine sapients regarded Displacers as too dangerous to move sapients.[4][13][7]

The probability of a catastrophic failure increased as the rate of Displacements increased.[3]


A snap-Displacement was a dangerous manoeuvre where a Displacer unit moving at very high superluminal speeds - relative to the target - executed a Displacement with extremely limited time-on-target,[4][14] perhaps as little as less than a millisecond.[15]

A typical snap-Displace could only handle a small volume.[4][15] The Culture Emergency Displacement required a pan-human to scrunch into a fetal posture.[4][16] Injury and damage would result if the targeting was not perfectly accurate.[13][16]


Displacing could be blocked by 4D shielding.[17]
