I both love and hate videos like this. I think it's a great introduction to astrophysics (John exempted) for people looking to understand the basics. But, the computer simulations and other graphic components are not used for instructional purposes, they are used for entertainment purposes and it is so frustrating. We're left to watch pretty colors swirling while someone's voice speaks of singularities and wormholes, white holes etc. etc. Nothing is labeled, nothing is diagrammed. It's not the most damning of complaints perhaps, but in my whole life I have yet to see someone get this right.
