You are possibly describing the idea of the cosmological horizon? It is possible (some believe very likely) that our universe is infinitely large, but since it is expanding faster than light we will never be able to see or interact with anything past a certain distance. This leaves our visible universe finite.
If some alien was living in a non-expanding infinite universe, it could be possible to simulate our “finite” portion of the universe.

>A cosmological horizon is a measure of the distance from which one could possibly retrieve information. This observable constraint is due to various properties of general relativity, the expanding universe, and the physics of Big Bang cosmology. Cosmological horizons set the size and scale of the observable universe. This article explains a number of these horizons.
