Beyond the Big Bang

   2007    Science
The universe began with a massive expansion, billions and billions of years ago, and it continues to expand with every passing second. The idea that the universe, and man's very existence, began with a "Big Bang" is no longer a topic of debate among most scientists--it is essentially taken as fact.

The Alien Planets

   2007    Science
Have planet hunters finally found proof of other Earth like worlds? Astronomers have now discovered over two hundred alien worlds, beyond our solar system, that were unknown just a decade ago. Discover planets that rage with fiery hurricanes and bizarre planets covered by water so dense that it forms a kind of hot ice. Among these weird worlds, Earth actually seems like the oddball.

Cosmic Holes

   2007    Science
Today, we know black holes exist, and now scientists are trying to confirm that other holes lurk in hyperspace. Our infinite cosmos could contain a variety of "holes" such as black, white, "mini" and wormholes. White holes are the reverse of black holes; instead of matter being sucked into it, matter is ejected out. Wormholes are gateways in the fabric of space and time. They are included in Einstein's field equations as possibilities for their existence. Neither white holes nor wormholes have ever been found. Learn about new discoveries including, colliding binary black holes, intermediate black holes and manufacturing mini black holes.

The Milky Way

   2007    Science
We used to think that Earth was at the centre of the universe, but now we know we're not even at the centre of our own galaxy. Countless wonders exist between where earth is situated and the massive black hole at the galactic centre of our galaxy. Within the Milky Way can be found the debris of old, dying stars fuelling the birth of new stars and at the galactic centre hypervelocity stars get catapulted clear beyond the Milky Way's outer rim at unimaginable speeds. Come along for a guided tour of 100,000 light-year-wide family of stars and stellar phenomena we call The Milky Way.

Alien Moons

   2007    Science
Travel from the inner solar system to the Kuiper Belt and explore the moons surrounding the planets of the solar system. Many of these moons that were once unknown are now on the cutting edge of astronomical study. Some burst with volcanic fury another spews icy geysers and others offer the possibility of alien life. Are these strange worlds simply hostile environments unfit for humans or do other possibilities exist? Cutting-edge computer graphics are used to bring the universe down to earth and to imagine what kind of life forms might evolve in alien atmospheres.

A documentary film or documentary is a non-fictional motion-picture intended to "document reality, primarily for the purposes of instruction, education or maintaining a historical record".

Early documentary films, originally called "actuality films", lasted one minute or less. Over time, documentaries have evolved to become longer in length, and to include more categories. Some examples are educational, observational and docufiction. Documentaries are very informative, and are often used within schools as a resource to teach various principles. Documentary filmmakers have a responsibility to be truthful to their vision of the world without intentionally misrepresenting a topic.

Documentary practice is the complex process of creating documentary projects. It refers to what people do with media devices, content, form, and production strategies to address the creative, ethical, and conceptual problems and choices that arise as they make documentaries. Documentary filmmaking can be used as a form of journalism, advocacy, or personal expression.

Box office analysts have noted that this film genre has become increasingly successful in theatrical release with films such as Fahrenheit 9/11, Super Size Me, Food, Inc., Earth, March of the Penguins, and An Inconvenient Truth among the most prominent examples. Documentaries are shown in schools around the world in order to educate students. Used to introduce various topics to children, they are often used with a school lesson or shown many times to reinforce an idea.

Media platforms have provided an avenue for the growth of the documentary-film genre. These platforms have increased the distribution area and ease-of-accessibility.
