Here's the hard part about trying to predict the end of the world by watching for foretold cataclysmic events: there have always been cataclysmic events. Does that meteor strike mean Jesus is just around the corner? Not necessarily. What about when combined with this afternoon's asteroid fly-by? It's open to interpretation.
But it's not a fool's errand to look for signs of Christ's coming; Jesus specifically commands his followers (in Matt. 24) to do so. I mean, there's really no reason to show signs in the heavens if we immediately discount them all as random natural phenomena.
Here's something else that's been sort of interesting to me lately: Baba Vanga's supposed prediction that America's 44th president would be its last, and Saint Malachy's supposed prediction that the incoming pope will be the last and Rome will be destroyed during his reign. Do these mean anything? I don't know. Far be it from believers in continual revelation to say these are prima facie false.
