If the vast majority of reality is beyond our direct perception, what does this imply about our understanding of 'truth' or 'completeness' in any domain?

Dark matter reminds us that our sensory experience and even our scientific instruments only grant us access to a sliver of reality. Just as we inferred dark matter's existence through its effects, there might be other fundamental aspects of existence—in physics, consciousness, or society—that operate beyond our immediate awareness. This insight encourages intellectual humility and an openness to radically new paradigms, even if they challenge our current 'complete' understandings.
