This article deals with the theoretical possibilities of expanding object-oriented ontology. In the first half of the article, it is argued that both object-oriented ontology and actor-network theory can gain theoretical edges when applied together. This article uses some famous examples from science and technology studies (STS) to show this. After that, the concepts of hyperobjects and nano-objects are explored. Hyperobjects are objects that are so vastly spread out in time and space that humans cannot easily recognize them. Nano-objects, a new concept suggested in this article, lie on the opposite side of the spectrum to hyperobjects. Nano-objects are so miniscule that humans cannot easily recognize them. Five characteristics of nano-objects have been identified so far: translucency, global locality/local globality, technoscientific relatedness, crossover existence between the nature/culture divide, and their scattered existence. At the end of the article, artist Ji-Hye Yeom’s work will be analyzed as a case study.
