Answer · Eye of the Sahara and Atlantis

# No: Plato's rings span about 5 km, and the 127-stadia match depends on leaving out part of a 40–45 km structure

Plato's rings and island together are 27 stadia across, about 5 km; the 127-stadia figure adds the city wall, and it matches the Richat only by measuring an inner ring and leaving out the outermost of a structure 40 to 45 km wide.

**Still possible** Answers **1** question0

## Where it stands

**Still possible** Two pieces of evidence for, none against. It needs two reviews to be accepted.

## What it predicts

- The Richat's full diameter is far larger than 127 stadia for any accepted stadion.
- Plato's ring proportions do not recur in the Richat's ridges.

## What would rule it out

- A measurement showing the Richat's whole system of rings is about 23.5 km across, in Plato's proportions.
