Limits RegistryPUBLIC RECORD
Limits RegistrySirius (Alpha Canis Majoris), a binary star system 8.6 light-years away, has an apparent magnitude of -1.46 — the brightest star in Earth's night sky, roughly twice as bright as the second-brightest, Canopus. Its brightness comes from a combination of its intrinsic luminosity and relative closeness to Earth, rather than being the most luminous star known.
The question, scope, and sources behind this Registry record.
Sirius (Alpha Canis Majoris), a binary star system 8.6 light-years away, has an apparent magnitude of -1.46 — the brightest star in Earth's night sky, roughly twice as bright as the second-brightest, Canopus. Its brightness comes from a combination of its intrinsic luminosity and relative closeness to Earth, rather than being the most luminous star known.
The lowest (brightest) apparent visual magnitude of any star as seen from Earth, excluding the Sun. Apparent magnitude is an inverse-logarithmic scale — a lower or more negative number means a brighter object.
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.
