It could be one of the most ambitious computer projects ever conceived.
An international group of scientists are aiming to create a simulator that can replicate everything happening on Earth - from global weather patterns and the spread of diseases to international financial transactions or congestion on Milton Keynes' roads.
Nicknamed the Living Earth Simulator (LES), the project aims to advance the scientific understanding of what is taking place on the planet, encapsulating the human actions that shape societies and the environmental forces that define the physical world.
"Many problems we have today - including social and economic instabilities, wars, disease spreading - are related to human behaviour, but there is apparently a serious lack of understanding regarding how society and the economy work," says Dr Helbing, of the Swiss Federal Institute of Technology, who chairs the FuturICT project which aims to create the simulator.
The most ambitious simulation project? Not by a long shot. But certainly among the most ambitious simulation projects being widely reported on.
But how would such colossal system work?
For a start it would need to be populated by data - lots of it - covering the entire gamut of activity on the planet, says Dr Helbing.
It would also be powered by an assembly of yet-to-be-built supercomputers capable of carrying out number-crunching on a mammoth scale.
Although the hardware has not yet been built, much of the data is already being generated, he says.
For example, the Planetary Skin project, led by US space agency Nasa, will see the creation of a vast sensor network collecting climate data from air, land, sea and space.
In addition, Dr Helbing and his team have already identified more than 70 online data sources they believe can be used including Wikipedia, Google Maps and the UK government's data repository Data.gov.uk. - source
