This document discusses how difficult it is to compare the size of the universe to our world given our limited knowledge. Specifically, no one knows precisely how big the universe is, how many stars exist, or what may exist on distant stars. While modern technology allows us to detect some approaching meteorites, larger threats from space could endanger Earth but are impossible to conclusively anticipate or answer questions about. The document concludes that the size of the universe relative to our world is an interesting but unanswerable topic of philosophical discussion.
