About this episode

<p>The Polar Opposite No one knows why the Earth's magnetic North and South poles swap. But polar reversals have happened hundreds of times over the history of the Earth. John Turk emailed curiouscases@bbc.co.uk to ask, “when is the next pole swap due and what will happen to us?” Featuring Prof Lucie Green from Mullard Space Science Laboratory and Dr Phil Livermore from the University of Leeds. Plus, astronaut Terry Virts, author of The View from Above, describes his experiences of a strange magnetic glitch in the earth's magnetic field, known as The Bermuda Triangle of Space.</p><p>The World That Turns "Why does the Earth spin?" asks Joe Wills from Accra in Ghana. Hannah quizzes cosmologist Andrew Pontzen about the birth of the Solar System. BBC weatherman John Hammond describes the curious things that would happen if the Earth spun the opposite way.
