landmarks

When a great man stands on a land for a moment, the land becomes not just a great land for a moment, but a great landmark!

With increasing distance, our knowledge fades, and fades rapidly. Eventually, we reach the dim boundary__he utmost limits of our telescopes. There, we measure shadows, and we search among ghostly errors of measurement for landmarks that are scarcely more substantial. The search will continue. Not until the empirical resources are exhausted, need we pass on to the dreamy realms of speculation.
