I've watched it, but his explanation (which is the best I've seen; don't misread me), basically goes into why it looks "thus" when viewed edge-on of the accretion disk. But there are as few like that as there are viewed from the poles; so why do they ALL look like this? If that's just the way it is I'll accept it, but I haven't heard or seen a good explanation yet.
