I just recently heard on the radio that the world was ending this weekend?

yes i heard last night in AUS that a man in America (whom is a christian) added to holy numbers together and multipyed them etc. and then added the day jesus rose from the dead i think and that was April 1st he said 2 % or somthing will go to heaven and the others will just vanish, then i heard that the tectonic plates are going to move dramatically causing the world to end this comming weekend on saturday at 6pm which is Sunday 6pm in austalia how did he come up with this? and im quite scared and pissed because i have just wasted 12 Years of my life at school. is this true? why is everyone thinking the world is going to end!
