it's not a "hoax" or "fake".it's a belief that it will happen at that time. some of the theories seem likely,but saying the date when it happens is a little far fetched.
here all knows some says its likely to happen and some says its not going to happen , whats the point ? that NASA scholar is explaining as much as he can, we who dont know what he knows about the solar system still not ready to believe that it wont happen hmmm, sad.
Im not sure why people are so scared. Its because of the movie...but scientist have been wrong every time. They said in 1996 an asteroid was going to hit, never happened. They said in 2000, the sun was going to die,never happened. They said in 2002 something dramatically was going to change, never happened. Get my drift?
