A "must-see" for anyone who is fascinated by our Universe and how its structure came to be. Maybe...

A National Geographic presentation. I found this at my public library on DVD. The picture and sound, or course, are superb. The film, which runs roughly 90 minutes, makes ample use of relevant Hubble telescope images plus ground-based images to explore and explain the Universe, and in particular our own Milky Way galaxy.What happened immediately after the "big bang"? Why do Astronomers believe there HAS TO BE something called "dark matter" that is more massive than the visible universe and that provides the gravitational structure responsible for the arrangement of the billions of galaxies? Why will our Milky Way galaxy cease to exist as we know it in a mere 2.5 Billion years?December 2017 edit: Now an Astrophysicist has proposed a theory for the Universe which does not rely on Dark Energy and Dark Matter. Maybe we will live long enough to see how that turns out!These and many more questions are addressed and explained in a way that we laymen (non-Astrophysicists) can comprehend. They do it in a clever manner, they use the analogy of a person living in the far suburbs going downtown to a large city. For the person, they use the planet Earth. It, in our solar system, resides in a rather "rural" part of the Milky Way galaxy. But "downtown", which is packed with stars and hot in both temperature and destructive cosmic radiation, would be a very dangerous place in comparison.We on Earth are very comfortable in our little solar system, which has changed very little for a few Billion years, enabling life to form and evolve. There is good discussion of the possibility of life-sustaining planets elsewhere, and what kinds of observations and specialty instruments are being developed to facilitate that.I have been interested in the "night sky" since I was a small boy on an inflated truck inner tube watching for meteors. I am a scientist, but actually know relatively little about Astrophysics, and I found this film interesting from start to finish.I give it my highest recommendation for those who are interested in the subject, our Universe and our Milky Way galaxy.Any why will our Milky Way galaxy cease to exist as we know it? The galaxy Andromeda is moving towards our Milky Way galaxy at a great speed and they will collide in roughly 2.5 Billion years. They will not be destroyed, instead will interact in a way to form a single larger galaxy with a vastly different shape. Computer modeling shows what that interaction may look like, and they show real Hubble images of merged galaxies that look virtually identical to the computer images. Leave a note for your descendants, to watch for it in a couple of Billion years!

This is a good documentary, but its main flaw is that it is not what it claims to be about. It is only tangentially about the Milky Way. It's more about the universe in general. I had expected something that would map our view of the Milky Way onto a 3D model of it. I had expected that we'd pick out many interesting features. I wasn't so much interested in how they got there or where they are going (for this documentary). Given the completeness of the Milky Way we are shown, I suspect it's largely an artist's conception, rather than a model.
Some further nits to pick:
If you think the terms "star city" and "miraculous" should be used repeatedly in a science documentary, then this may be for you. But the dumbing-down of content in this manner started to irritate me.
Dark matter, of course, has not been discovered. That's why we call it "dark matter". It's expected, but it has never been discovered. It's also possible that our understanding of gravity is inaccurate (as if that hasn't happened many times before).
Also, the picture of the early universe was presented as if it were visible light, but that's a radio telescope picture. If they went to lengths (see what I did there?) to explain infrared, visible, and X-ray images, why not this?
And I was disappointed that the computer-simulated universe which "perfectly" matches our own was not actually overlaid so we could see how perfect the match was with our own eyes. It's bizarre they would just make the claim without showing it.
But generally it's a good overview of the universe, touching on a wide variety of topics including the life cycle of stars, types of stars, life cycle of galaxies, history of the universe, life, astronomical techniques, globular clusters, ultra-faint dwarf galaxies, and Andromeda. It's unusual to have all of this pulled together into a single presentation, and it does earn 7/10.
