The end of the world is nigh. That's what top astronomers will claim during a debate to end the 2011 Edinburgh International Science Festival.
Lord Martin Rees, the Astronomer Royal, believes civilisation has only a 50 per cent chance of surviving to 2100 without suffering a man-made catastrophe.
And the Astronomer Royal for Scotland, Professor John Brown, has an equally bleak outlook, fearing a random event from outer space is the most likely cause of our demise.
They will take to the stage to put forward their stark predictions in the discussion "Fire in the Sky: Cosmic Threats to Earth".
Despite having widely differing views, these two titans of astronomy between them offer global warming, over-population, terrorism, an asteroid falling to earth and a solar blast as potential reasons to panic.

so accroding to you, if only 90% of us die, that`s nothing to be alarmed about? and actually if you take into account the difference in physical strength and the dependance on technologies that will no longer be available... I really have a hard time believing that about 600 to 700,000,000 of us would survive a mass extinction level event such as those experienced by our ancestors. people will be killing EACHOTHER at unheard of rates in the months following a global breakdown, is my prediction. I would say that within a year or two following such a cataclysmic event, we would be down to less than 500,000 survivors including any new births... I offer no credentials, psychic claims or links, only my own original thoughts. As original as a thought CAN be, that is. Let`s just hope we can avoid a disaster like this from happeningat least in the next 90 years. Maybe in 900 we will be better equipped to handle it
