As you may (or not) know, some people were predicting the end of the world to be a couple of weeks ago. This morning I read it's been rescheduled for this Sunday. A wandering planet-size object called Nibiru is going to collide with Earth and kablooie!
I don't have any information why nobody with a telescope has actually seen Nibiru yet. That would seem to be a big flaw in this theory, but, hey, it's prophecy, you know?
