Just read the CERN article, lol! There's absolutely nothing to indicate it's a joke, no "funny" tag or anything, so I'll just go ahead and put my trust in science and believe all of it!
nitesh9's article I'll read later, it looks very interesting but also quite longer!
Well, they put it on the web on April 1st. There is one of such joke every year :p
No, they updated it on April 2nd. So I believe them.
Naaah, don't :)
