Boris Shustov, director of the Institute of Astronomy, said at a forum that the Apophis asteroid could have a bigger impact than an asteroid that hit Siberia in 1908, the Novosti news agency reported. (source)
If this is true, it will only be another 22 years before it happens. It sounds like the movie Armageddon. An asteroid is heading towards earth and men are trying to save the planet by either destroying the asteroid or shifting its course. Blasting the asteroid may not be an option since the article stated that it may cause more harm than good.
What if the asteroid does hit earth? What if you are unfortunate enough to be directly affected by the asteroid hit? What would you wish to do? What about the rest of the world that will be indirectly affected by it?
