Explore the extraordinary world beneath our feet, as spectacular CGI takes us to the least understood place on the planet: The Core.
Get up close and personal with Earth in a way you probably have never imagined. Down to the Earth’s Core takes viewers from the sidewalk to the centre of the planet in one epic unbroken shot. Using spectacular computer generated imagery; the camera smashes through almost 9 000 kilometres of solid rock to explore the hidden world beneath our feet.
Experience an earthquake inside the San Andreas Fault, blast out of a volcano, encounter bizarre cave-dwelling creatures and enter caves full of giant crystals — all inside planet Earth.
As the camera lowers into Earth’s bosom, the planet’s extraordinary story, is laid bare layer by layer, showing how prehistoric forests became modern-day fuel, witnessing the dinosaur’s cataclysmic death, and watching as stalactites form and gold grows before our eyes.
Deeper, beyond the reach of any mine, any drill, we find wonders beyond imagination: towering molten metal tornadoes, forests of solid iron crystals, until we reach the strangest, least understood place on the planet — the core. To infinity and beyond, this is Earth like never before.
The hottest place on earth, even hotter than the sun’s surface, lies 6400 kilometres away, in the inner sanctum of our planet. Take a journey from the footpath to the centre of earth in one epic unbroken step, smashing through solid rock to explore the hidden world beneath our feet.
Deeper, beyond the reach of any mine, any drill, we find wonders beyond imagination: towering molten metal tornadoes, forests of solid iron crystals, until we reach the strangest, least understood place on the planet – the core. Withstand intense forces of heat and pressure along the way, to discover the home of the raw materials that shape and power our civilisation.
Human ingenuity has allowed us to uncover many secrets in our universe, from dark matter to the moon and even outer space. And yet we still have no idea what lies in the very heart of our own home planet – earth’s core. From the earth’s surface, this documentary examines the forces that affect our lives including plate tectonics, the formation of gold, diamonds and oil.
Through computer technology, we see how earthquakes are born from waves of energy blasting through hundreds of kilometres of solid rock, a grim reminder of the violent forces hidden below our feet.
Ironically, our planet is both destroyer and creator. The same intense tectonic forces that cause volcanoes and earthquakes also help to form two of our most prized possessions, gold and diamonds.
As we journey deeper beneath the surface, more facts are revealed: how colonies of humble bacteria rendered the earth livable, how the iron that keeps civilization standing was formed, and how a thick layer of dead plankton on the ocean floor was transformed into the oil upon which we are now so dependent.
Four and a half billion years since our planet first evolved, we owe our existence to the heat at its core. Everything that makes our world beautiful – and volatile – is derived from this almighty, ancient energy source.
