Sun-Sirius Radius Ratio in Quran | Stellar Mathematics
Surah 91 and 53 encode Sirius's exact radius: 91÷53 = 1.717 solar radii. A mathematical miracle discovered 1400 years after revelation.
Did You Know?
Surah 91: الشمس 'Ash-Shams' (The Sun) Surah 53: النجم 'An-Najm' (The Star) - mentions Sirius The ratio: 91 ÷ 53 = 1.717 Sirius A radius: 1.713 ± 0.009 solar radii Match within measurement precision. Sirius radius measured by stellar interferometry in the 2000s, 1,400+ years after the Quran.
He is Lord of Sirius
Quran 53:49
Explanation
The Quran dedicates Surah 91 to the Sun and Surah 53 to stars—specifically naming الشِّعْرَىٰ 'Sirius' (the brightest star). The ratio of their surah numbers (91/53) encodes Sirius's radius in solar units. This astrophysical constant requires interferometric measurements impossible before modern telescopes.
Scientific Details
The Numbers
Surah 91 (The Sun) ÷ Surah 53 (The Star) = 1.717 | Sirius A measured radius: 1.713 ± 0.009 R☉ | Difference: 0.23% (within measurement error)
Stellar Interferometry
Measuring star radii requires stellar interferometry—combining light from multiple telescopes to achieve high resolution. Sirius A's radius was precisely measured in the 2000s using techniques developed 1,400+ years after the Quran.
