How can one know if a world is a digital construct or not? Just looking isn’t enough. A game world seems real because when I look left, a left view is shown and when I look right, a right view is shown. Wherever I look, the game world presents but the catch is only when I look. In contrast, an objective reality exists whether I look or not, so it shouldn’t change depending on how I look. Yet quantum theory says this is not true of physical reality and the evidence agrees. It predicts an observer effect and photons in delayed choice experiments do indeed choose a physical path to a detector after they arrive. How you look affects what you see in our world just as in a virtual reality. So does our physical world manifest other tell-tale signs of being a virtual reality?
