Doctor Who is a British science fiction television series first broadcast by the BBC in 1963. The series, created by Sydney Newman, C. E. Webber and Donald Wilson, follows the adventures of the Doctor, an extraterrestrial being from a humanoid species known as Time Lords. The Doctor travels through space and time using a time travelling spaceship called the TARDIS, which has an exterior that resembles a British police box. The Doctor encounters various civilisations, which they seek to protect by outwitting foes and solving crises. The Doctor usually travels with a companion.
Beginning with William Hartnell, fourteen actors have headlined the series as the Doctor; the most recent being Ncuti Gatwa, who portrayed the Fifteenth Doctor from 2023 to 2025. The transition between actors is woven into the story via the plot device of regeneration. When a Time Lord is fatally injured or weakened by old age, their cells regenerate into a new body; while they retain their memories, their personality changes. The different portrayals function as distinct stages within a single, continuous narrative. Due to time travel, these different incarnations occasionally cross paths.
A British popular culture staple with a global cult following, the show has shaped generations of British television professionals. Fans of the series are sometimes referred to as Whovians. The series has been listed in Guinness World Records as the longest-running science-fiction television series in the world, as well as the "most successful" science-fiction series of all time, based on its overall broadcast ratings, DVD and book sales.

The Space Museum is a serial in the British science fiction television series Doctor Who, which was first broadcast in four weekly parts from April 24 to May 15, 1965. The story is set on the planet Xeros, a subjugated planet in the Morok Empire, now home to a vast museum and a young, rebellious population.
The Doctor and his companions experience something strange after they land on the planet Xeros. Shattered glass mends itself, footprints fail to materialize in the sand, and everything is silent. And then, inside a gigantic museum, they find something even more alarming: themselves.

| “ | On my travels to Cathay, Ian, I have come to believe many things I'd previously doubted. For instance, when I was a boy in Venice, they told me that in Cathay there was a stone that burned. I did not believe, but there is such a stone: I have seen it. And if stone burns, why not a caravan that flies? Birds fly; I have even seen fish that fly. You are asking me to believe that your caravan can defy the passage of the sun? Move not merely from one place to another, but from today into tomorrow, today to yesterday? No Ian, that I cannot believe. | ” |
