Universe from Bitcoin block #709,494
Stars but no life有恒星无生命
Grade A · no observers
Stars, planets and chemistry all exist in this universe. What is missing is time or a stage: stars burn out too quickly, or the habitable window is too short for anything complex to develop.

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 (709,494). 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.
