Are space and time fundamentally unified, or are they distinct aspects of reality?

Modern physics treats space and time as a single spacetime continuum, yet everyday experience and some philosophical traditions still regard them as distinct. I am interested in how physics, metaphysics, and human perception intersect on this issue, and whether the unity of space and time is fundamental or merely a useful theoretical framework.

From my experience engaging with both philosophical debates and physical theory, I have seen that the unity of space and time depends heavily on the level of analysis. In relativistic physics, spacetime functions as a single entity with remarkable explanatory power. Yet I would recommend caution in treating this as the final ontological word. Our lived experience, and some philosophical accounts, still meaningfully distinguish temporal flow from spatial extension. Philosophically, the tension suggests that spacetime may be fundamental at the physical level while remaining conceptually or phenomenologically differentiated at the human level.
