Doctor Who stories are many things: thrilling adventures, historical dramas, tales of love and war and jelly babies. They’re also science fiction – but how much of the science is actually real, and how much is really fiction?

The Scientific Secrets of Doctor Who is a mind-bending blend of story and science that will help you see Doctor Who in a whole new light, weaving together a series of all-new adventures, featuring every incarnation of the Doctor. With commentary that explores the possibilities of time travel, life on other planets, artificial intelligence, parallel universes and more, Simon Guerrier and Dr Marek Kukula show how Doctor Who uses science to inform its unique style of storytelling – and just how close it has often come to predicting future scientific discoveries.

This book is your chance to be the Doctor's companion and explore what's out there. It will make you laugh, and think, and see the world around you differently.

Because anything could be out there. And going out there is the only way to learn what it is.

Doctor Who Logo 'Sunset Over Venus'

by Mark Wright
The Twelfth Doctor and Clara


The Doctor and Clara arrived inside the Genetrix, an observation capsule suspended from a balloon in the thick, poisonous atmosphere of Venus. Shortly after they meet the crew, Devika and Rick, the pod goes out of control and the tether to the Lovell Platform high above breaks. As the capsule plummets towards the planet below, all aboard know they will be crushed by the extreme atmospheric pressure long before impact. The Doctor deduces that gas samples taken by the crew are actually the planet’s indigenous life form, gaseous creatures that live in the clouds. One such creature has attacked the capsule to free its comrades, but when the Doctor orders the release of the sample, the Venusians lift the pod and its occupants to safety.

The Doctor comes to the rescue of the space ship Godspeed, whose hull has been covered in space barnacles. One of the crew has already been killed by the creatures, his space suit drained of all power after he went outside to investigate a power loss. The captain tries shooting the ship’s weapons at the creatures, but this only causes them to multiply. Explaining that the space barnacles feed on energy, the Doctor orders a complete systems shutdown, and then draws the barnacles away from the Godspeedusing the power of his TARDIS as a lure; after the creatures have covered the his space-time vessel, the Doctor then takes the TARDIS to a remote star system in which the creatures can now live. Their ship now free, the captain and her crew continue on their way.

The Twelfth Doctor and Clara


Clara asks the Doctor to take her for a holiday in her home town of Blackpool, but when they arrive they find the place in ruins, the pier broken and falling into the sea, and the fairground attractions overgrown with thick vegetation. After saving a wild donkey from the senile cyborg landlady of a nearby run-down guest house, the two time travellers find themselves hunted as sport by spoilt rich kids riding in airborne dodgem cars. Deducing that the source of the vehicles’ energy comes from the top of Blackpool Tower, the Doctor and Clara climb the rusting edifice and manage to shut down the power. Without the use of their dodgem cars the hunters are powerless, allowing the Doctor and Clara to hand them over to the authorities. The threat over, the Doctor enjoys a ride in the surf on his new found friend, Meghan the donkey.

by James Swallow
The Doctor and Martha


When the Doctor and Martha arrive on Karadax, they come under attack from the planet’s bad-tempered shark-like inhabitants, who decide to test their prototype robot drone on them. Escaping into the sewers, the Doctor leaves Martha behind with a plastic box, while he rushes off after the robot. Martha is surprised when a portal opens next to her, and her apparent future self emerges: the older Martha warns her younger self to leave the Doctor, warning that her family will be put in jeopardy by the Time Lord’s future actions. Knowing that to do so will cause an historical paradox Martha is immediately suspicious, and questions her future self to prove her identity. The older Martha fails the test, and unmasks herself as a robot exhibitoid from the Reldeen ‘Museum of the Doctor’, sent from the Fifty-First Century to convince Martha to remove herself from the Time Lord’s timeline. When Martha refuses, another portal opens and a Karadax emerges: his subtle plan ruined, the warrior now intends to delete Martha himself. Changing back into Martha’s double, the exhibitoid seizes the Karadax and then overloads its circuits, sacrificing itself to override the warrior’s temporal recall module and sent him back to the future. Just then the Doctor returns, pursued by the drone; taking a sock from the box he left with Martha, the Doctor stuffs the smelly footwear into the robot’s sensitive sensor grid, causing it to short-circuit. Keeping her own side of events a secret, Martha leaves with the Doctor, ready to make history…

The Twelfth Doctor


The Doctor joins a troop of travellers on a pilgrimage across the Kingdom of Leon and Castile to the church at Santiago de Compostela. Arriving at a tavern, they are confronted by angry townsfolk, who blame them for the arrival of plague in the area and demand that they be quarantined in a nearby church. As they make their way to the church, the Doctor is delighted to learn that one of the pilgrims is Geoffrey Chaucer, although that soon turns to annoyance when he learns the man is only twenty-three, and yet to write any of his famous tales. The group arrives at the church just in time for another of the travellers, Matilda, to give birth. While the mother cradles her new son, the Doctor explains that the church is in fact a spaceship, and the wooden carvings that decorate it are really alive; these wooden creatures feast on the souls of the dead, and have been enjoying a bumper crop thanks to the Black Death afflicting the area. The evil aliens attack the pilgrims, but are stopped when they encounter Matilda’s baby: the child is anathema to the evil aliens, who are repulsed by the concept of new life. With some help from the Doctor, the creatures depart in their spaceship. Bidding goodbye to Geoffrey and the pilgrims, the Doctor returns to his own travels.

The Fifth Doctor


Arriving on the planet Lemaria, the Doctor, Tegan, Nyssa and Adric attend a popular play that celebrates the liberation of the planet from alien oppressors. Their surprise at seeing a familiar blue police box standing on the stage quickly turns to amazement when an actor dressed as the Doctor’s first incarnation appears, and engages in a re-enactment of the time he once saved the planet’s inhabitants from attacking Megrati. The Doctor realises that the actor is in fact one of his future selves, who has returned to see off a revenge attack by the real Megrati. The Twelfth Doctor uses his sonic screwdriver to disrupt the crystalline engines of the invaders’ spaceships, forcing the Grand Megrati to abandon his invasion plans and flee in defeat. The assembled audience applaud as the alien fleet retreats, and the Twelfth Doctor gives his former self a knowing smile before making his exit in his TARDIS.
