Doomsday: Your End Of The World In Art, Science And Mythology

I'd better start by defining exactly what I have in mind with the phrase ‘the end of the world' as ‘the end' can take several forms.   Firstly though to the time it takes for an the end of the world event: A real end of the world scenario will be a short term event, lasting from mere seconds (say a gamma ray burster) to several months (say a pandemic, all out nuclear war, a super-volcano). I'm not talking multi-decades to centuries here as per global warming and rising sea levels or the coming of the next Ice Age.   The End of the World = the Destruction of Planet Earth ("When Worlds Collide" scenarios). That is, Planet Earth and obviously all and sundry on same go down the gurgler.   The End of the World = the Destruction of All Life on Planet Earth
