Why is it that the UK don't want to have any knowledge in regards to what will happen in 2012? Yet in America & Asia they are fully aware of what will happen in 2012, I also know that scientists are fully aware of what may happen.

Why aren't the public aware & how can we destroy what is coming towards planet Earth? This meteor willl destroy every satellite known to government, knock the power grid in USA.  Leaving us all in darkness.

No phones, No network, No Internet, No freedom, what is going to happen?

One often hears proposals to deflect or destroy an incoming asteroid with a nuclear explosion. Given that this occurs in "empty" space, what mechanism couples the energy, or impulse, between the bomb and the asteroid?

When making the case for a Near Earth Object deflection strategy, many people focus on larger extinction-class asteroids. From my research, it seems that strikes from "small" asteroids (such as the 1908 Tunguska asteroid, which is now believed to have been only 40 or 50 m in diameter) are more frequent. In addition, a Tunguska-sized asteroid strike over a populated area or in the ocean--although not an extinction-class event--could still potentially kill millions of people, cause severe ecological harm, wreck the global economy by disrupting the supply and distribution of goods and resources, and create a humanitarian crisis that could itself ignite conflict in already-tense areas of the globe. Given the risk that smaller asteroids pose, wouldn't it be prudent to develop a system to detect and deflect these "small" asteroids?
