The emergence of metaverse technologies introduces a new spatial dimension to journalism, extending news production, distribution, and consumption beyond conventional digital platforms. While research on filter bubbles and echo chambers has largely focused on two-dimensional online environments, this article draws on Henri Lefebvre’s theory of the social production of space to argue that immersive virtual worlds may reconfigure these dynamics through the algorithmic production of space. Based on a theoretical review integrating spatial theory, algorithmic gatekeeping, immersive journalism, and virtual reality scholarship, the article proposes two original concepts: algorithmic spatiality, the process through which algorithms produce, organize, and legitimize spatial experiences in virtual environments; and three-dimensional echo chambers, conceptualized not as homogeneous spaces excluding opposing views, but as conditional environments that shape the spatial, embodied, and affective framing of content. The study further argues that virtual reality may increase misinformation’s persuasive power by combining algorithmic curation with embodied and affective experience, positioning this as a theoretical hypothesis for future empirical testing. The article concludes by proposing three normative principles for Metaverse journalism -spatial transparency, spatial accountability, and spatial accessibility- offering a novel conceptual framework that integrates critical spatial theory with debates on algorithmic governance
