We live in a time when science is probing ever deeper into reality, from the inner life of cells to the outer edges of the universe. But the more we learn, the clearer it becomes that something slips through our fingers. Some things remain unresolved – perhaps even beyond understanding.

For science does not only give us answers. It also opens up abysses of new questions. Where is the boundary between what we know and what we truly understand? And are there limits to what we can ever grasp? Are some aspects of reality simply inaccessible to us – not because we lack the technology, but because we are human?

Welcome to a conversation about the outer edges of knowledge.
