Context: Time travel is the concept of movement (such as by a human) between certain points in time, analogous to movement between different points in space, typically using a hypothetical device known as a time machine, in the form of a vehicle or of a portal connecting distant points in time. Time travel is a recognized concept in philosophy and fiction, but traveling to an arbitrary point in time has a very limited support in theoretical physics, and usually only in conjunction with quantum mechanics or wormholes, also known as Einstein-Rosen bridges. In a more narrow sense, one-way time travel into the future via time dilation is a well-understood phenomenon within the frameworks of special relativity and general relativity, but advancing a large amount of time is not feasible with current technology. The concept was touched upon in various earlier works of fiction, but was popularized by H. G. Wells' 1895 novel "The Time Machine", which moved the concept of time travel into the public imagination, and it remains a popular subject in science fiction., The Eighth Doctor Adventures (sometimes abbreviated as EDA or referred to as the EDAs) are a series of spin off novels based on the long running BBC science fiction television series "Doctor Who" and published under the BBC Books imprint. 73 books were published overall., Unnatural History is an original novel written by Jonathan Blum and Kate Orman and based on the long - running British science fiction television series Doctor Who . It features the Eighth Doctor , Sam , Fitz and Faction Paradox ., Doctor Who is a British science-fiction television programme produced by the BBC since 1963. The programme depicts the adventures of a Time Lord called "The Doctor", an extraterrestrial being from the planet Gallifrey. He explores the universe in a time-travelling space ship called the TARDIS. Its exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired. Accompanied by a number of companions, the Doctor combats a variety of foes, while working to save civilisations and help people in need., The British Broadcasting Corporation (BBC) is a British public service broadcaster. It is headquartered at Broadcasting House in London, is the world's oldest national broadcasting organisation, and is the largest broadcaster in the world by number of employees, with over 20,950 staff in total, of whom 16,672 are in public sector broadcasting; including part-time, flexible as well as fixed contract staff, the total number is 35,402., Faction Paradox is a fictional time travelling cult/rebel group/organized crime syndicate, originally created by the author Lawrence Miles. The Faction's belief-system as portrayed has some similarities to voodoo, and is sometimes described as such. The family/organization were originally featured as recurring antagonists in the BBC "Doctor Who" Eighth Doctor Adventures novels, but have since featured in their own continuing tales. , Lawrence Miles (born 15 March 1972 in Middlesex) is a science fiction author known for his work on original "Doctor Who" novels (for both the Virgin New Adventures and BBC Books series) and the subsequent spin-off Faction Paradox.

Unlike an ordinary callbox, its telephone was located behind a hinged door so it could be used from the outside, and the interior of the box was, in effect, a miniature police station for use by police officers to read and fill in reports, take meal breaks and even temporarily hold prisoners until the arrival of transport., Subject: unnatural history , Relation: publisher, Options: (A) bbc (B) bbc books (C) box (D) century (E) portal
