How can we know if our world is virtual 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, it presents but the catch is, only when I look. In contrast, an objective reality exists whether I look or not, so physical events shouldn’t change when observed differently. Yet quantum theory predicts an observer effect, that how we observe events changes their properties, and the evidence agrees. In delayed choice experiments, photons observed differently take different paths to a detector. The physicist Wheeler concluded that we live in a participatory universe, where what we see depends on where we look, just as expected for a virtual reality. So, does our world exhibit any other tell-tale signs of virtualism?
