From Nostradamus and the ancient Mayans to modern-day scientists, the
theoretical "apocalypse" has been the source of endless speculation and
countless predictions, with anything from super-volcanoes to
mega-tsunamis, rogue planets or a massive methane eruption leading to
the so-called "end of life as we know it." In this series, some of the
world's leading scientists, along with elaborate computer graphics,
illustrate the different "what if?" theories of if and how catastrophic
weather or natural disasters could possibly cause the end of days or
transform our lives forever.
