recently heard the rumor for the asteroid collision to earth that will happen 2019.....I say that we have been tracking this for years now so i believe that the government will prevent it...there are 3 ways to prevent it
1st is to collide an object into it
2nd is to make a slight gravitational attraction to the object and steer it clear from earth
3rd and actually can happen nowadays is that we can fire a nuke at it to split it into a smaller asteroid
so i say we will be fine....remember the whole rumor where the world would end December 23rd 2011....were still here guys -_-......don't buy what people are saying and remember WE HAVE THE TECHNOLOGY!
