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.
