I think this gives the song credibility as it is a relatable example. I think comparing feeling lost with outer space is a great way to express that feeling.

These lyrics make the audience believe what he is saying. He is using very relatable language. Even when you feel lost you still know where you belong deep down, it's just a matter of making your way there

I think the space metaphor is a perfect way to display weightlessness of being lost. I also like how these lines show how these emotions can consume you just like space.

These lines are a pivotal moment in the song. They represent finding your truest self. The artist says these lines are about "even when all seems lost,[you] can still go back to what is deep within [yourself]"(Taylor).

These lines express how scary the path to finding your way. It can be daunting falling into something you don't know (coming back to earth) when you were lost (in space) for so long.
