A massive Porites coral colony discovered off the Solomon Islands in 2024, nicknamed 'Muracake,' is estimated to be over 300 years old and is visible from space, among the largest and oldest single coral colonies documented; separately, some Hawaiian black coral colonies have been radiometrically dated to over 4,000 years old using growth-band and isotopic methods, representing an even older extreme for coral longevity.
The question, scope, and sources behind this Registry record.
A massive Porites coral colony discovered off the Solomon Islands in 2024, nicknamed 'Muracake,' is estimated to be over 300 years old and is visible from space, among the largest and oldest single coral colonies documented; separately, some Hawaiian black coral colonies have been radiometrically dated to over 4,000 years old using growth-band and isotopic methods, representing an even older extreme for coral longevity.
The oldest age estimated by growth-band or radiometric dating for a single, continuously living coral colony documented in scientific surveys.
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.
