- Simple Science Explanations: Are we living in a simulation? Scientific viewThe simulation hypothesis, proposed by Nick Bostrom, suggests that advanced civilisations could create realistic simulations of conscious beings. While intriguing, science currently lacks empirical evidence to support or refute this idea. Physics describes a consistent natural universe, making the hypothesis more philosophical than scientific, with no practical implications for our reality.
