EXISTENTIAL UNCERTAINTY  

Our Final Century: Will the Human Race Survive the Twenty-first Century is a 2003 book by one of Britain’s top scientists Royal Sir Martin Rees. The premise of the book is that the Earth and human survival are in far greater danger from the potential effects of modern technology than is commonly realised, and that the 21st century may be a critical moment in history when humanity’s fate is decided. Could this be one cosmologist’s apocalyptic belief, an implausible science fiction scenario or is it actually an important area of study that requires a great deal more scientific investigation than they presently receive?
