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.
Knowledge collider
Thanks to projects such as the Large Hadron Collider, the particle accelerator built by Cern, scientists know more about the early universe than they do about our own planet, claims Dr Helbing.
What is needed is a knowledge accelerator, to collide different branches of knowledge, he says.
“Revealing the hidden laws and processes underlying societies constitutes the most pressing scientific grand challenge of our century.”
The result would be the LES. It would be able to predict the spread of infectious diseases, such as Swine Flu, identify methods for tackling climate change or even spot the inklings of an impending financial crisis, he says.
But how would such colossal system work?
