I'm working on my graduation project for CS, which is about cellular automata. Recently, i was able to build a system where the input is transferred to multiple different structures at once. The input consists of numbers, a sequence of numbers ranges from (-infnite to infinite), like ('5','65443'or'9921075').

From the sequence of numbers {input}, i can see each number's behavior and how it interacts with other numbers by analysing the different structures it outputs, it is like a Cellular Automaton structure simulates another Cellular Automaton structure.

How can i relate these properties to universality, What should i look for or analyze in these structures to show universality?
