Could We All Be Living In A Computer Simulation?

In 2003, philosopher Nick Bostrom proposed the simulation hypothesis, which officially put forth the idea that our universe might be a computer simulation. Both scientists and Hollywood directors have since addressed this notion and its variants, but few people have suggested feasible tests for proving or disproving it. In 2012, a team at the University of Washington said that looking for a limitation in the energy of cosmic rays might be indicative of a simulation's "signature." Others have said that unexplained physics phenomena might be "glitches" in the simulation, which could never be a perfect copy of a real universe. Building a simulation ourselves would help us to determine what these glitches look like, and subsequently search for them in our own universe. However, the technology needed for simulating a universe (inside our own, which may or may not be a simulation itself) is not yet available.
