For centuries we have dreamt of reaching the centre of the Earth.

 

Now scientists are uncovering a bizarre and alien world that lies 4,000 miles beneath our feet, unlike anything we know on the surface. It is a planet buried within the planet we know, where storms rage within a sea of white-hot metal and a giant forest of crystals make up a metal core the size of the Moon.

Horizon follows scientists who are conducting experiments to recreate this core within their own laboratories, with surprising results.

  • Professor Dan Lathrop has built a 3 meter model of the earth's core which he plans to fill with twelve metric tons of liquid sodium, and then spin at up to eighty-five miles an hour.
     

  • Professor Kei Hirose has managed to recreate the extreme temperatures and pressures found at the centre of the earth somewhere rather more convenient to study: his own laboratory.
