I was talking about the planets with my 5-year-old daughter the other day. I was trying to explain how taking a summer vacation to Mars in the future will be a much bigger undertaking than a trip to Palm Springs (though equally as hot). I kept trying to describe the distance using metaphors like “if the earth was the size of a golf ball, then Mars would be across the soccer field” etc., but I realized I didn’t really know much about these distances, besides the fact that they were really large and hard to understand. Pictures in books, planetarium models, even telescopes are pretty misleading when it comes to judging just how big the universe can be. Are we doing ourselves a disservice by ignoring all the emptiness?
