A hailstone weighing 1.02 kg (2.25 lb) fell on Gopalganj District, Bangladesh, on April 14, 1986, during a storm that killed 92 people — the heaviest hailstone ever officially recorded, per the World Meteorological Organization. This is a distinct record from the largest hailstone by diameter (a 2010 stone from Vivian, South Dakota, USA, measuring about 20 cm across), since diameter and mass records are not always held by the same stone.

The greatest mass of any single hailstone officially recorded and verified, as distinct from records for largest hailstone diameter.

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.
