May 21st...Judgement Day?

Okay well im Muslim so i kinda do think anything is gonna happen to us today. Because in the Qu'ran or maybe Prophet Muhammed P.B.U.H. said that the world is supposed to end on a Friday and guess what?! its Saturday!! None of the MAJOR signs on Qiyamat have happened such as that big giant, the sun setting in the east instead of the west, and more. So i want to know who thought of this theory about May 21 2011 cuz i think their REALLY stupid. And even in the Bible and Quran it says that no one will know Judgement Day...so i wanna know how the people who think were dying today and nobody dies will feel...really stupid for sure..
