What is a deep space or hole too large to measure?

A deep space or hole too large to measure typically refers to regions in the universe or structures, such as black holes or cosmic voids, that defy conventional measurement techniques. For instance, a supermassive black hole's event horizon may be beyond our current understanding, making its size difficult to quantify. Similarly, vast cosmic voids are expansive areas between galaxies where matter is scarce, making their boundaries challenging to define. Ultimately, these phenomena highlight the limitations of our measurement capabilities in the vastness of the universe.
