The Soviet thermonuclear bomb known as Tsar Bomba was air-dropped over the Novaya Zemlya test site on 30 October 1961 and produced a yield of about 50 megatons of TNT (estimates range from 50 to 58 Mt) — the most powerful explosion ever created by humans.

The Soviet thermonuclear bomb known as Tsar Bomba was air-dropped over the Novaya Zemlya test site on 30 October 1961 and produced a yield of about 50 megatons of TNT (estimates range from 50 to 58 Mt) — the most powerful explosion ever created by humans.
The largest explosive yield of any nuclear weapon ever detonated.
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.
