If the universe is just a Matrix-like simulation, how could we ever know? Physicist Silas Beane thinks he has the answer
The idea that we live in a simulation is just science fiction, isn't it?:
There is a famous argument that we probably do live in a simulation. The idea is that in future, humans will be able to simulate entire universes quite easily. And given the vastness of time ahead, the number of these simulations is likely to be huge. So if you ask the question: 'do we live in the one true reality or in one of the many simulations?', the answer, statistically speaking, is that we're more likely to be living in a simulation.
