Limits RegistryPUBLIC RECORD
Limits RegistryGRB 221009A, detected on October 9, 2022 and nicknamed the 'BOAT' (Brightest Of All Time) by astronomers, was roughly ten times brighter than any previously recorded gamma-ray burst, with a measured fluence so high it temporarily blinded or saturated the detectors on several gamma-ray satellites. Originating about 2.4 billion light-years away, it also produced the highest-energy photons ever recorded from a gamma-ray burst, detected by the LHAASO observatory in China at energies up to 18 teraelectronvolts.

The highest total gamma-ray fluence (energy per unit area) measured for any gamma-ray burst since systematic satellite monitoring began in the 1990s.
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.
