Universe gives a way to have multiple big-bangs communicate.
Each big-bang is individually called a “world”. They are also called “clients”. There is one “universe” running, which is the “server”. The universe server coordinates all of the communication between the big-bang clients.
There are some new technical additions to big-bang
, and some recommendations for the design process.
