'39

Queen's song ''39'' is a unique piece that blends folk influences with the band's signature rock sound, and it tells a story that is both poignant and scientifically intriguing. Written by lead guitarist Brian May, who holds a degree in astrophysics, the song is a narrative about space travelers who embark on a journey only to return and find that many years have passed on Earth due to the time dilation effect of traveling at near-light speeds, a concept rooted in Einstein's theory of relativity.

The lyrics describe the departure of these volunteers in the year of '39, setting sail on a ship into the unknown. The 'ship' is a metaphor for a spacecraft, and the 'milky seas' represent the Milky Way galaxy. The travelers leave with hope and bravery, not knowing the personal cost of their journey. Upon their return, they find a world that has aged decades, while they have aged only a year. The emotional toll of this time disparity is captured in the lines where the protagonist realizes the life they knew is forever altered, and their loved ones have aged or passed away.

The song's chorus, with its haunting call across time, emphasizes the distance and separation between the traveler and those left behind. The writing of letters in the sand symbolizes the fleeting nature of attempts to bridge the gap between the past and the present. The traveler is left to grapple with the consequences of their journey, a poignant reflection on the sacrifices made in the pursuit of progress and exploration. '39' is a beautiful blend of storytelling, science fiction, and emotional depth, showcasing Queen's ability to craft songs that resonate on multiple levels.
