Multiversally-Unique ID's are going to be so long...

• zaarn 9y ago
  Depends on how many of them there are. If there is infinite, there is no MUID, if it's finite and below 2^64 then a traditional UUID should be enough to assign a UUID per universe and then assing a UUID for objects within.

    > If there is infinite, there is no MUID Formally, you could still have MUIDs even if there are infinite universes so long as they are countably infinite. Practically, the system would work as well so long as you could allocate new qbits to boost your information exponent.

      Well, no, as long as you want a finitely long MUID since a finite number of digits can only express a countable but not infinite number of elements.

        We don't want a finitely long MUID, otherwise we couldn't represent infinite universes. A quantum bit represents infinite states. The "fiction" part is that we (currently) need to collapse quantum bits.

  I was going to disagree because our universe seems to be very compressible and a lot of the properties are just natural. I bet it could be defined in 0 - 100 bits at the "earliest" point. But over time, QM seems to make lots of arbitrary decisions and those also seem to create different universes if they end up contributing to macro behavior.
