第 1 季，第 2 集: The forces of nature have kept Earth on the move since it was formed billions of years ago and its epic journey through space shapes all our lives. Earth is spinning at an incredible speed, whilst at the same time orbiting the sun and yet we are not aware of this motion. In this episode, we take to the air in one of the world's most advanced aircraft, a Eurofighter Typhoon, in a carefully planned operation to outpace the spin of the Earth and for a few seconds stop the sun in it in tracks, hanging just on the horizon. In the Tropics, Earth's spin can set tropical storms in motion and these sometimes turn into hurricanes or typhoons. Earth moves through space with its constant companion, the Moon. A few times a year, the Earth, Moon and Sun align perfectly and the combined gravitational pull creates extreme tides. Few are more extreme than the tidal bore that surges up the Amazon River in Brazil - the Pororoca. Whilst the locals flee to escape the destructive power of this ferocious wall of water, one man seeks it out. We are all unwitting passengers on an epic journey through space as the Earth spins and orbits on its tilted axis. And humans mark the passage through the year with rituals like the Ardia, an epic horse race, held each year in the town of Sedilo, on Sardinia. With each passing year, we have travelled not only another 550 million miles around the Sun, but our entire Solar System is also moving with the spin of our galaxy, the Milky Way. Each year on Earth takes us another 4.5 billion miles through space. We are all space travelers, riding our own spaceship, Earth.
