All systems go, sun hasn't died
Deep in my bones, straight from inside
This just emphasizes how strong the emotions going through our narrator are. He is going to push on for this revolution until there is no more hope (i.e. the sun dies). And he states once again how he feels this all the way down to his bones.
The fact that the “sun hasn’t died” is important to what the writer of the song is trying to get across. After talking about apocalypses, possible nuclear war, and revolution, we can be sure the world still goes on. Reynolds wanted to make a dark song that still put out an empowering message, and I’d say he did a fine job.
“A lot of people hear it in a dark way, but… it’s empowering, and so we wanted to display that in a way that the listener wouldn’t see normally.”
