UPDATE: Phil Plait has a great article over on Slate about what these videos get right and what they get wrong. In the first video he shows the sun leading the planets which is not true, they are all in the same plane. In the second video he gets the angle of the solar plane wrong (it’s 60° not 90°) and while our solar system does bounce above and below the galactic plane the corkscrew he shows is totally bunk. Also his numbers regarding length of galactic orbit are way off. Plait acknowledges that he gets some things right and it’s a very beautiful video but as far as science goes it needs to be take with a “galactic size grain of salt”.
The author of these videos readily admits that he is not a scientist and that there are flaws with his models, but I suspect that in broad strokes his vision is mostly correct. It’s certainly worth viewing if for no other reason than to understand that the flat model we use for orbits is not just wrong, but incredibly boring.
His second video is even more scientifically questionable but it’s still worth watching. He posits that even how our solar system orbits the black hole at the center of our galaxy is not as simple as we might imagine.Leave a comment
