Deep Impact??

When I watched the clips about Planet X, the first thing that came to my mind is the movie "Deep Impact". A movie about a comet that is discovered heading towards Earth. The plot describes the attempts to prepare for and destroy a Comet, which is expected to collide with the Earth and cause an Extinction Level Event. (An extinction event is a sharp decrease in the number of species in a relatively short period of time.) In the movie, the government conducted a lottery to select 800,000 ordinary Americans to join 200,000 pre-selected scientists, engineers, teachers, artists, soldiers and officials. These people would be part of a worldwide effort to save mankind from extinction.

In the weeks and months that follow, not only these few individuals but everyone in the world must struggled to find meaning for their lives in the face of looming catastrophe. A plan was set in motion to establish underground shelters, "Arks," in which a fortunate few may survive the impact even if all other life on Earth was wiped out. As the day of cataclysm grew nearer, all the range of human reactions was evoked -- from panic to noble resignation to fate.

"Deep Impact" is the story of the world's reaction to a death sentence.

Will this be the same situation in 2012? Will there be chaos? or like I said is this only a conspiracy... Do you think this will happen?
