> And not that it is even an interesting question but my take is no this is not a simulation. Way too much detail. Even if some civilization had the resources to run a simulation the size of our universe it would be a massive waste to do so. The most efficient computational system for simulating a universe with the high fidelity our universe has is to create a universe and let it evolve. I also don't think we live in a simulation, but if we did, how can you know anything about the outside universe, leave alone its resource limitations? Perhaps what we consider to be huge and complex (our own universe) is the equivalent of a simple Conway's Game of Life to the outside world.
