If there’s one concept sci-fi has been fascinated with for almost as long as the genre has existed, it’s time travel. That’s especially true on television, where dozens of shows have sent their characters hurtling back into the past or jumping forward what lies ahead. Even series that aren’t dedicated to the idea still find room for an adventure through time. Space operas, speculative anthologies, and even superhero shows have all explored the consequences of tampering with history or discovering a future that was never meant to happen.
