Kraken Mare, a sea of liquid methane and ethane near the north pole of Saturn's moon Titan mapped by the Cassini spacecraft's radar, covers roughly 400,000 km² — larger than the Caspian Sea, Earth's largest lake. Titan is the only other world known to have stable liquid on its surface.

The largest surface area of any known stable body of surface liquid on a world other than Earth.
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.
