Space, as Douglas Adams once so aptly wrote, is big. To try imagining
how big, place a penny down in front of you. If our sun were the size
of that penny, the nearest star, Alpha Centauri, would be 350 miles
away. Depending on where you live, that’s very likely in the next state
(or possibly country) over.
Attempting to imagine distances larger than this quickly becomes
troublesome. At this scale, the Milky Way galaxy would be 7.5 million
miles
