This blog post will be a little different than the rest in that I will be asking more questions with my analysis. I’m hoping that you can help me analyze this further in the comments section because I would really appreciate your insight.
I have always wondered what happens to time inside the TARDIS, specifically in regards to the companions. The show indicates that the human companions live on a short timeline, which begs the question, Do they age inside the TARDIS? Does it somehow stop time and they stay the same age no matter how long they are in there? Or do the companions start aging again once the TARDIS reaches its destination and they are back in the regular time stream?
I wonder about these things because the Doctor laments often that he cannot travel with a human companion forever because they wither and die, but if time is irrelevant in the TARDIS, the humans would never age as long as they kept travelling in the TARDIS. It’s confusing, really, and the show never really explores these things. So, can you spend time in a time machine and not die? I like to think that the TARDIS suspends time, and as long as humans stay with the Doctor, they do not age at the normal rate. Obviously, the actors will age as they spend more time on the show, so it will not look like the TARDIS stops the aging process. I see this as a huge dilemma for the overarching plotline and the history of the TARDIS.
So, I think the companions stop aging inside the TARDIS. Do you? What is your interpretation of this hole in the story?
