Earth's Iron Core Depth 5100km in Quran
The numerical value encoded in Surah Al-Hadid points to Earth's iron core depth: 5,100 km. Geological precision.
Did You Know?
The verse about iron being أنزلنا 'anzalna' (sent down) is verse 57:25. Its position from the start of the Quran: approximately verse 5,100. Depth to Earth's inner iron core: 5,100 km. Perfect positional encoding. The iron in Earth's core was literally sent down from space—formed in supernovae and delivered via meteorites billions of years ago.
And We sent down iron, wherein is great military might and benefits for the people
Quran 57:25
Explanation
The word 'sent down' (أنزلنا 'anzalna') describes iron's cosmic origin—forged in dying stars and delivered to Earth. The verse's position at ~5,100 from the Quran's start encodes the depth where Earth's iron concentration peaks. Discovered by Inge Lehmann in 1936 using seismic waves, 1,300+ years after the Quran.
Scientific Details
The Numbers
Verse 57:25 position: ~5,100 | Inner core depth: 5,100 km | Core composition: 85% iron, 10% nickel | Outer core starts: 2,890 km
Historical Discovery
Earth's core structure was unknown until seismology. Inge Lehmann discovered the inner core in 1936 by analyzing earthquake waves. The iron core's existence wasn't confirmed until the 20th century.
