Limits RegistryPUBLIC RECORD
Limits RegistryThe Rub' al Khali (Empty Quarter), spanning parts of Saudi Arabia, Oman, the UAE, and Yemen, covers roughly 650,000 km² of continuous sand — the largest contiguous sand sea (erg) on Earth. This is a distinct comparison from the Sahara's status as the largest hot desert overall, since much of the Sahara is rocky or gravel terrain (reg and hamada) rather than sand.
The question, scope, and sources behind this Registry record.
The Rub' al Khali (Empty Quarter), spanning parts of Saudi Arabia, Oman, the UAE, and Yemen, covers roughly 650,000 km² of continuous sand — the largest contiguous sand sea (erg) on Earth. This is a distinct comparison from the Sahara's status as the largest hot desert overall, since much of the Sahara is rocky or gravel terrain (reg and hamada) rather than sand.
The greatest surface area of any single contiguous sand sea (erg), as distinct from the total area of a broader desert region that includes rocky or gravel terrain.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
