the documentary is basicly as if your sitting inside a car while driving around the universe, they start off by examining our solar system, then our galaxy and then go into intergalactic space(outside our galaxy), everything is done as if its from your P.O.V
some of the topics you can find in it(apart from the recreations of beautiful satellite images that you get to see): descriptions of planets within our solar system(with a few of theyre moons), various different solar systems and stars, different galaxys, the search for life within the universe, the creation of stars, death of stars, supernovas, blacks holes, white dwarfs etc. etc., theres far too much to name but you probably get the picture, we're just moving across the universe until we reach the edge of it(as we move further and further its like as if we go back in time so at the end they show the origins of the universe)
the whole thing lasted 2 hours, they split it up into numerous parts on youtube
also, there seems to be 2 versions of the documentary, one is done by national geographics and the other by discovery(i think its the same documentary just with a different narration), i saw was the discovery channel one
ya man i seen it too its fucken amazing, it'd make you think how insignficant your everyday life is, and how your problems isn't really a problem if u look at the "REAL" big picture.
