I used this fact to consider a plausible simulation hypothesis. I had assumed you would need a universe larger than ours to simulate ours. However, assuming that since all the other places are far away, and we have found no other intelligent life, then it may be possible that we live in a simulated world in a Universe that is the same size or smaller than ours, since they would only need enough space to simulate the complexities of Earth at a low level, and the rest of the entire Universe could either be simulated at a very high level, or simply filled in.
