Time travel has always been a fascinating concept, and it's no surprise that it has become a staple of science fiction. From H.G. Wells' 'The Time Machine' to the numerous adaptations of his work, time travel has captured our imagination for over a century.
However, it wasn't until the 1960s that time travel became a central theme in Doctor Who. The show's creators, Sydney Newman and Verity Lambert, were inspired by Wells' work as well as other science fiction authors like Isaac Asimov and Arthur C. Clarke.
As we explore the concept of time travel, it's essential to consider the ethical implications. If we can travel through time, do we have a responsibility to change the course of events? Or should we leave the past alone?
This is precisely the dilemma that the Doctor and his companions face in many episodes. They often find themselves in situations where they must decide whether to intervene or not.
Time travel has also allowed us to explore the consequences of altering historical events. What if we were to go back in time and change the outcome of a pivotal battle or prevent a catastrophic event?
This raises questions about the nature of free will and whether our actions can have unintended consequences on the timeline.
