If you think it's unlikely that we will all be sucked into a giant black hole that will swallow the world, as German chemistry professor Otto Rössler of the University of Tübingen posits, and so carry on with your life as normal, only to find out that it's true, you'll be a bit miffed, won't you?
If, on the other hand, you disagree with theoretical physicist Prof Sir Chris Llewellyn Smith of the UK Atomic Energy Agency, who argues that fears of possible global self-ingestion have been exaggerated, and decide to live the next two days as if they were your last, and then nothing whatsoever happens, you'd feel a bit of a fool too.
