The journey to the center of the earth is a voyage like other we can imagine. Over 3000 km below the earth's surface, an extraordinary inner world the size of Mars awaits us. Dive through the molten iron of the outer core and eventually you will reach a solid sphere -an iron-clad world held within a metal sea and unattached to anything above. At the earth's core is the history of our planet written in temperature and pressure, crystals and minerals ...Our planet appears tranquil from outer space. And yet the arcs of volcaes, the earthquake zones, and the auroral glow rippling above our heads are testimony to the remarkable happenings within the earth's core. For thousands of years these phemena were explained in legend and myth. Only in recent times has the brave new science of seismology emerged. One hundred and fifty years after the extraordinary, imaginative feat of Jules Verne's Journey to the Center of the Earth, David Whitehouse embarks on a voyage of scientific discovery into the heart of our world. Seismologists today reveal a planet astonishingly buried within a planet. We watch as supercomputers convert signals from the ground into three-dimensional scans of subterranean continents. We will visit laboratories where scientists attempt to reproduce the intense conditions at the center of the Earth, travel down the throat of a volca, look into the deepest hole ever drilled, and imagine a voyage through ermous crystals of iron...all at the center of our incredible Earth.
