Viral Video Showing Sun’s “Vortex” Motion Is Wildly Inaccurate

Posted: February 8, 2016 in Uncategorized

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.

excerpt: "how things should be and how they are don’t always overlap. The Universe is a pretty cool place, and works using a fairly well-regulated set of rules. We call those rules physics, they’re written in the language of math, and trying to understand all that is science."
