Asteroid 2008 TC3, about 4 m across, was discovered by the Catalina Sky Survey on 6 October 2008 and struck the atmosphere over Sudan's Nubian Desert about 19 hours later, as predicted. A search organized by SETI Institute astronomer Peter Jenniskens with the University of Khartoum later recovered about 600 meteorite fragments, named Almahata Sitta.

The first time an asteroid was discovered in space and its impact on Earth predicted before it occurred.
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.
