Universe from Bitcoin block #74,687 — Big Crunch

The expansion of this universe does not last. Gravity wins, the expansion halts and reverses, and everything is compressed back toward a single point. Whatever structure formed on the way out is destroyed on the way back.

On-chain, this universe lives in the same MirrorUniverse contract on BNB Chain as every BNBBANG universe, with blockHash = the Bitcoin block hash and blockNumber = its Bitcoin height (74,687). The contract’s verified flag is false for every Bitcoin-origin universe: BNB Chain cannot look up a Bitcoin hash, so the flag simply does not apply — that is the expected state, not an error. Anyone can confirm the origin by fetching this height from any Bitcoin node or explorer and comparing the hash.
