Limits RegistryPUBLIC RECORD
Limits RegistryMagnetars — neutron stars with extreme magnetic fields — are the most strongly magnetized objects known. SGR 1806-20, about 50,000 light-years away in Sagittarius, has an inferred dipole field of roughly 2 x 10^11 tesla (2 x 10^15 gauss), around a quadrillion times Earth's field; its December 2004 giant flare was the brightest event from outside the solar system then recorded.

The highest magnetic field strength inferred for any known astrophysical 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.
