Understanding the Legacy and Science of Queen’s “’39”
Few songs in the history of rock music manage to bridge the gap between complex theoretical physics and emotive, folk-inspired storytelling. Queen’s track “’39,” released as part of their seminal 1975 album A Night at the Opera, remains a standout piece in the band’s catalog. Composed by lead guitarist Brian May, the song serves as a unique exploration of time dilation and the human cost of relativistic space travel.
The Narrative Behind the Music
At its surface, “’39” tells the story of a group of astronauts who depart on a voyage that they perceive to be one year in duration. Because they are traveling at relativistic speeds—speeds approaching the speed of light—the effects of time dilation cause a profound discrepancy upon their return. While the crew has aged only a year, they arrive back on Earth to discover that a full century has passed. The loved ones they left behind have aged or passed away, leaving the travelers as ghosts in their own time.
Brian May, who holds a doctorate in astrophysics, drew directly from his scientific background to craft the lyrics. However, May has noted that the song functions on multiple levels. While the space-faring narrative provides the structure, the song also reflects on the personal experience of being away from home and witnessing a world that has irrevocably changed—a sentiment May felt during his early years navigating the burgeoning rock music industry.
Musical Composition and Recording
Musically, “’39” stands apart from the bombastic, operatic stadium rock that defined much of Queen’s work in the 1970s. The track is rooted in skiffle and folk traditions, utilizing acoustic instrumentation that creates a sense of intimacy and longing. A notable feature of the recording is the inclusion of a double bass, played by bassist John Deacon. According to May, the inclusion of the instrument began as a joke, but Deacon quickly mastered it, adding a distinct rhythmic foundation to the song.
The track is also significant for its lead vocals. Brian May provides the lead, making it one of the rare instances in Queen’s discography where the guitarist took the primary vocal role rather than Freddie Mercury.
Key Takeaways
- Astrophysical Inspiration: The song is a literal application of Einstein’s theory of special relativity, specifically time dilation, where time slows down for objects moving at high velocities.
- Genre Departure: “’39” leans into folk and skiffle influences, showcasing the band’s versatility beyond their signature hard rock sound.
- Personal Subtext: Despite its sci-fi premise, May intended the song to reflect the universal feeling of returning home to find that one’s personal world has moved on.
- Rare Vocal Performance: The track features Brian May on lead vocals, marking a departure from the band’s standard vocal arrangements.
Frequently Asked Questions
What is the scientific basis for the song?
The song is based on the concept of time dilation, a consequence of Albert Einstein’s theory of relativity. It posits that time moves slower for an object in motion relative to an observer at rest. In the song, the astronauts’ high-speed journey results in them returning to a future where their friends and family have aged significantly more than the crew themselves.

Is “’39” a science fiction song?
While it utilizes science fiction tropes, it is better described as a narrative ballad. The setting of space travel is used as a metaphor for the alienation and temporal displacement one feels when experiencing significant life changes or long absences from home.
Where can I find the official release?
The song was originally released on the 1975 album A Night at the Opera and later served as the B-side to the hit single “You’re My Best Friend” in 1976.
As of May 2026, “’39” continues to be celebrated by fans and critics alike as a testament to Queen’s creative range and Brian May’s ability to synthesize intellectual curiosity with compelling songwriting.
