Limits RegistryNASA's Stardust spacecraft flew through the coma of comet Wild 2 in January 2004, capturing dust grains in ultra-light aerogel, and its capsule landed in the Utah desert on 15 January 2006. Analysis revealed minerals formed at high temperatures near the young Sun, showing material was mixed widely across the early solar system.

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.
