The evidence
2 source verses, an interactive observation, and three deliberately separated readings.
The boundary
A resonance is not a scientific prediction. These studies invite reflection; they do not turn scripture into a laboratory manual.
Before the instrumentGuess first
How much of a mountain lies beneath it, invisible, like the buried part of a peg?
Hold your guess. Then run the experiment below.3.0 km
A peg's grip is buried, not shown. At this height the root reaches about 13.5 km down, roughly 4.5x the height above ground: the mountain floats on the mantle the way a peg floats stable only when driven deep.
The verses
What the text says
The text: Have We not made the earth a resting place, and the mountains as pegs?
What classical readers understood
The peg image (awtad) is the tent peg: what stabilizes by being driven in.
What science sees
Isostasy: mountain ranges float on the mantle with deep crustal roots, often several times deeper than the visible peak is high, like an iceberg or a driven peg.
