Universe from Bitcoin block #420,073
Heat death, no structure热寂——无结构的宇宙
Grade A · no observers
Density fluctuations are too small for gravity to gather anything. The universe stays an almost uniform gas that keeps diluting and cooling forever, and no galaxies, stars or planets ever condense out of it.

Constants are reported in an external frame. Only α and αG are observable from inside the universe; c, h, e and G can be rescaled without changing what its inhabitants could measure.

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 (420,073). 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.
