Limits RegistryPUBLIC RECORD
Limits RegistryIceCube, buried in roughly a cubic kilometer of clear Antarctic ice at the South Pole, instruments about 1 km³ of ice with 5,160 optical sensors — the largest neutrino detector ever built, discovering the first astrophysical high-energy neutrinos in 2013. The larger successor, IceCube-Gen2, is planned but not yet complete.
The question, scope, and sources behind this Registry record.
IceCube, buried in roughly a cubic kilometer of clear Antarctic ice at the South Pole, instruments about 1 km³ of ice with 5,160 optical sensors — the largest neutrino detector ever built, discovering the first astrophysical high-energy neutrinos in 2013. The larger successor, IceCube-Gen2, is planned but not yet complete.
The largest contiguous instrumented volume of any operating neutrino detector, measured in cubic kilometers of detection medium.
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.
