This chapter explores virtual reality within digital culture, examining its dual role as both space and interface. Building on Ted Striphas’s work on algorithmic culture, it defines key terms like cyberspace and digital space, tracing VR’s evolution from early online interactions to immersive 3D environments. It contrasts virtual realism with virtual irrealism, arguing that VR constitutes a real, though digital, space. The chapter also addresses the physical-virtual continuum and VR’s ontological status, questioning its capacity to host the sacred. Finally, it introduces VR’s implications for sacramental and liturgical practices, setting the stage for theological engagement.
