Universe zoom videos (i.e., Universe zoom videos):

1. Contact Zoom Out from Earth | 5:17: OK for classroom as an opening video or if you want to describe it as it goes along since there is no narrative. There is music and "Tis poetical". It's a bit long, but depending on the time available and your mood, it might be OK to show the whole thing. It's NOT totally accurate. Going through the asteroid belt, it shows asteroids densely packed. Solar System maps show a dense packing since there hundreds of thousands of significant asteroids, but they are really tiny compared to their separations. If you were standing on one, you would only see others as faint stars if at all. Too long for the classroom.
2. cosmic voyage to elsewhere : The scale of the Universe | 5:57: OK as an opening. No narrative. Passes through Fermilab and Venice. Pretty. Works as a music video too. Too long for the classroom.
3. IMAX Cosmic Voyage | 8:49: Pretty, but a bit slow for classroom. Another opening video. Maybe too long even for that. Starts in Venice---the center of the universe. It seems to be a version of the other Venice zoom video. After a zoom-out, a zoom-in. Too long for the classroom.
4. Cosmic Zoom (High Quality) | 8:00: The old National Film Board of Canada zoom-out, zoom-in video---the grandfather of zoom videos, the Ur-zoom video: Cosmic Zoom (1968). I remember seeing this is in the 6th grade or so, ∼ 60 years ago. It starts in Ottawa and it isn't high quality. Too long for the classroom.
