"Blackhole" is about feelings of desperation and the search for meaning in a seemingly meaningless world. "Is there nothing but the cold at the center of a black hole?" Architects vocalist Sam Carter questions. He delivers the line with the kind of intensity that suggests he's not expecting a comforting answer.

Drummer Dan Searle said in an Apple Music interview that the song reflects on mortality and the daily struggles that feel enormous until they're framed against the rather unhelpful fact that we are all, ultimately, temporary. "It's about the battles we face day to day - and how insignificant so much of our suffering is in the face of inevitability." This concept will be familiar to those familiar with Buddhism.

Searle, of course, knows a thing or two about grief. His twin brother, Architects' guitarist and primary songwriter Tom Searle, passed away from skin cancer in 2016, an event that understandably reshaped the band's perspective on, well, everything. "All of us see friends or family get sick, and it stirs up all sorts of thoughts and feelings," he said. "When we wrote that song, that had come up in our lives. I was asking myself, 'What's this all about? And why am I wasting my time suffering over nothing?'" Which is the sort of question best asked with a pummeling guitar riff in the background.
