IN AN EFFORT TO IMPRESS HIS NEW COMPANION, THE Doctor takes Rose Tyler five billion years into the future to see the end of her world. They arrive on Platform One, a space station orbiting the now-deserted Earth. The sun is expanding and would have engulfed the planet already were it not for gravity satellites holding it back. But the money to maintain the satellites has run out and the destruction of Earth is now imminent. Using ‘psychic paper’, the Doctor gains access for Rose and himself to an exclusive event in which rich and privileged guests will witness the ‘Earth-death’ from the platform.
