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 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.

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.
