“I’ve been getting lots of tweets and email from folks linking to a slick-looking video, a computer animation showing the motion of the planets around the Sun as the Sun orbits around the Milky Way Galaxy. It’s a very pretty video with compelling music and well-done graphics.

“It’s wrong. And not just superficially; it’s deeply wrong, based on a very wrong premise. While there are some useful visualizations in it, I caution people to take it with a galaxy-sized grain of salt.”
