Abstract: Heidegger is the founder of modern metaphysics who inquired about “being”, while the nothingness of things and the disappearance of the nearness of being caused by technology-economy are the central problem. Virilio’s historical analysis of the relativity of the environment and the displacement of the “being” based on the speed opened up a new thought of post-heidegger nihilism criticism. From Virilio’s point of view, transportation and communications technologies are moving into the “real time” phase, space-time is reduced to “time-light” represented by electromagnetic wave vibration, “being” of here and now is dissolved, people become “remote presence”, therefore, we must ask whether we are living “in the world” or “out of world”. In general, Virilio asks through the relation between existence and speed, and it deepens the ontological view of social critical theory.
