In 2003 Swedish philosopher Nick Bostrom raised the question: Are you living in a computer simulation?
Now scientists say they can test whether that’s the case or not.

Bostrom posited a compelling argument that at least one of the three following propositions is true:

1. The human species is very likely to go extinct before reaching a ‘posthuman’ stage;
2. Any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof);
3. We are almost certainly living in a computer simulation.
