how does marvel name its universes? like, 616? 1610?? TRN123??? are they just random numbers?
I think they’re just random numbers! (I know that 616 is the main one though, and 1610 I think proooobably is the Ultimate one?)
It’s based on the year and the month it came out for the first few. So 616 is because the first issue of the Fantastic Four came out in June 1961. Similarly, Earth 811, the Days of Future Past Earth was created in January 1981. Marvel eventually abondoned that, but most of the first few au worlds follow that numbering scheme. (up to the mid 90s at least)
OMG, I never knew that! Cool!
