Limits RegistrySuper-Kamiokande, located about 1,000 meters underground in the Kamioka mine in Japan, holds 50,000 tonnes of ultra-pure water instrumented with over 11,000 photomultiplier tubes — the largest water Cherenkov detector in operation, responsible for landmark discoveries including evidence for neutrino oscillation that earned Takaaki Kajita a share of the 2015 Nobel Prize in Physics.
The question, scope, and sources behind this Registry record.
Super-Kamiokande, located about 1,000 meters underground in the Kamioka mine in Japan, holds 50,000 tonnes of ultra-pure water instrumented with over 11,000 photomultiplier tubes — the largest water Cherenkov detector in operation, responsible for landmark discoveries including evidence for neutrino oscillation that earned Takaaki Kajita a share of the 2015 Nobel Prize in Physics.
The greatest instrumented water volume, measured in metric tonnes, of any operating underground water Cherenkov radiation detector used for neutrino or proton-decay physics.
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.
