My last skeet got me thinking: Are UUIDs unique across Marvel's multiverse? Let’s explore this mathematically, and spoiler: infinity makes things complicated 🤯 🧵 (1/7)

UUIDs (Universally Unique Identifiers) have 3.4 undecillion possibilities - an astronomical number that keeps collisions practically impossible in a single universe. But with infinite universes, collisions are inevitable. Why? Because infinity beats finite, no matter how big 2/7

If each universe generates UUIDs independently, eventually you’ll get duplicates across the multiverse. In theory, that’s not a problem unless the universes interact - like they do in Marvel. Suddenly, duplicates can cause chaos in tracking and identification (3/7)

To solve this, you’d need a Multiverse Universal Identifier (MUID): <Universe-ID>-<UUID>. Example: Earth-616-550e8400-e29b-41d4-a716-446655440000. The Universe-ID ensures UUIDs remain unique across realities (4/7)

But who assigns Universe-IDs? Is there a universal registry? Without a central authority, different universes could use conflicting numbering systems, or even reuse the same Universe-ID! This leads to multiversal indexing conflicts (5/7)
