  • thats great for children, as well as for adults that dont know much about cosmology.

  • The"Ask an Astronomer" video is by far the best I have found. The verbal descriptions could not be clearer or simpler. The technical accuracy of the animations is outstanding, but also, the way the animations are designed makes the concepts amazingly understandable. The animations showing moon phases are brilliant. Nothing else comes close.

  • @NewEarthDweller Yeah how they know such a thing? They just assumed it. Who the fuck knows. It might blow any minute.

  • @EarthProf Yes. Basically they explain it like in a ' for dummies' way. You know? That yellow book? I love to read those because they are simply explained. Just like this.

  • Wow,never thought of it that way.
