Universe from Bitcoin block #421,504
Unstable orbits无稳定轨道 / 无稳定原子的宇宙
Grade B · no observers
In this universe the number of spatial dimensions is not three. Gravitational orbits and the ground states of atoms are both unstable, so matter cannot settle: it either collapses inward or disperses. Nothing lasting can be built from 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 (421,504). 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.
