"Simulacra" refers to copies or representations of things that no longer have an original or that distort the original's meaning. The term is often associated with the work of philosopher Jean Baudrillard, who argued that in a postmodern society, these representations can become more significant than reality itself. In this context, simulacra can be seen in various forms, such as advertisements, media, and virtual realities, where the distinction between the real and the artificial blurs. This phenomenon raises questions about authenticity and the nature of reality in a world increasingly dominated by images and symbols.
