Naked Science tackles the science of one of the biggest mysteries of our time - natural phenomena.
The earth is 4.5 billion years old and it is slowly dying. Tectonic activity is slowly cooling the planet – the continents will eventually move together to form a new supercontinent called Pangea Ultima. Once formed they will not separate again. Once it has cooled the liquid core will solidify and lose its magnetic properties – the earth will no longer be shielded from the lethal solar radiation emitted from the sun. This solar wind will blast away our atmosphere – the air pressure will drop, liquid water will boil away into space and without the warming cocoon of the atmosphere the whole planet will cool to hundreds of degrees below zero. Slowly the planet will die – the ocean will dry up and the earth becomes an arid freezing desert. Just like Mars – which died billions of years ago when it also lost its liquid protective core. Then in five billion years the Sun too will die and as it expands it will consume the earth burning the surface to a cinder. Naked Science tells the story of earth’s demise.
