In this TEDx talk Astrophysicists and a Nobel prize winner George Smoot discusses the exotic idea of the simulated universe. The idea that our reality might just be a simulation or a dream most likely originates from various school of thought in philosophy. In particular, since the times of ancient Greeks certain schools of philosophy considered the question of whether one should trust his senses. This eventually matured into such famous ideas as the brain in the vat and Descarte’s evil demon. All of these ideas are combined to form the so-called simulation hypothesis.
As crazy as all of these ideas sound, what do they actually have to do with modern physics? Well it turns out there are many good arguments from physics, brain science, computing and other fields showing that realistic simulations are within our reach in the near future. In this talk George Smoot will discuss both the philosophical angle of the topic and how it is related to modern physics problems. For more similar talks visit the links below.
