Please be reminded that the entity didn't said the world would be destroyed on the 15th of May. There will be just a huge change that will be extremely perceivable among all humans on Earth by that date. However, if what the entity predicted, such as timelines merging, cosmosonicboom, oil becoming uselss, weird stuff not happening by May 15 2013, then please just wait until May 22 2013, since that is the date I have a strong feeling for. But then again, it could be anytime between May 14 to May 22 2013.
