Communion Of Dreams


Putting things in perspective.

Happy Thanksgiving, to my American friends.

Perhaps thinking about giving thanks, and the question of my perspective from this vantage point in life, is what made this post from the Bad Astronomer pop out in my reading this morning. It’s about a scale model of the solar system hosted on the web. From the site:

This page shows a scale model of the solar system, shrunken down to the point where the Sun, normally more than eight hundred thousand miles across, is the size you see it here. The planets are shown in corresponding scale. Unlike most models, which are compressed for viewing convenience, the planets here are also shown at their true-to-scale average distances from the Sun. That makes this page rather large – on an ordinary 72 dpi monitor it’s just over half a mile wide, making it possibly one of the largest pages on the web.

Just for reference, the image of the Sun on my monitor is about 6″ diameter. Yeah, Pluto is a speck about 6,000x the diameter of the Sun away.

I love these sorts of things which convey the notion of deep distance (similar to the concept of deep time). One of these days I’d like to make it to Sweden to see the Sweden Solar System, which uses the Globe arena to represent the Sun, with Pluto a sphere about 5″ in diameter almost 200 miles away.

This question of scale – of the deep distance from one planet to another here in our solar system – is one which I tried to deal with honestly in writing Communion of Dreams. It’s why it takes over a week for the researchers sent out from Earth to reach Saturn (Well, Titan, actually) even using a constant thrust of about one-third gravity, and why there is a time-lag in radio communications of about 90 minutes (yeah, I researched not just the average distances between the planets, but where they would be in their respective orbits on the dates in the book – as well as what the intermediate time lag would be en route at various points). Which presented a problem in the writing – what to do with the characters in the book during this period? Which, in turn, is what I think made the readers at the publisher feel that the book moved too slowly in the first half.

Well, I still haven’t heard back from the publisher about the revisions I sent (and I didn’t expect to yet), so I don’t know whether I was able to address this concern adequately with the changes I made. And once I do hear, I expect that my perspective on the matter will change – as it always does, after the fact. Such is life. Such is the universe.*

Again, Happy Thanksgiving.

*Thanks, JB.

That’s why reading CoD is fun for the geeky-minded like me. You have real science in it, so I know it could happen someday. I enjoy the realism of it.
