This text examines the distinction between the terms "world" and "universe" (universum) within scientific and philosophical contexts. While astronomers and astrophysicists define the universe as the sum total of physical matter, energy, and spacetime structures originating from the Big Bang, this concept often excludes the dimensions of life, consciousness, and moral order. The author argues that a universe defined solely by physical phenomena does not constitute the "world as a whole" in its full integration. Conversely, the term "world" is frequently used to describe specific domains or "surroundings" (Umwelt), such as the world of art or mathematics, often without reflecting on its subjective integrity or its applicability to the universe as a whole. The text raises the question of whether it is possible to speak of a "world of philosophy" or a "world of ideas" in a similar way to physical systems. The central challenge lies in understanding the world as a genuine whole that integrates both objective reality and the subjective processes of thought and existence, moving beyond a mere collection of investigated astronomical entities.
