Many people have thought(s) about the reality of life. Is life real? Is the Earth actually an atom? Do we live in a dream? Is our world nothing more than a computer simulation? In 2003 the Swedish philosopher Nick Bostrom formalized the question and now scientists say they can test whether it is the case or not.
According to Bostrom 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.
Martin Savage a physics professor at the University of Washington and two colleagues, take the possibility that our universe is a numerical simulation serious.
