Bowen's work on nebulium proved that \"forbidden\" transitions weren't actually impossible—they just require an atom to sit undisturbed for seconds or minutes without bumping into another particle, something a terrestrial laboratory in the 1920s simply couldn't create. The [Astrophysical Journal paper by Bowen in 1927](https://ui.adsabs.harvard.edu/abs/1927PASP...39..295B/abstract) effectively turned deep space nebulae into the first functional low-density vacuum chambers.
