Humans as Universes
Even though we roughly know how the universe works, we still don't have a satisfactory way of describing our personal experiences. The laws of physics, as we know them today, allow one to accurately simulate the time evolution of a person who is being tortured. But this doesn't explain the feeling of being tortured. Or perhaps it does? Perhaps all there is to our experiences of the physical world is a calculation. There exists a mathematical description of us and that is precisely what we are. The universe in which we live is ultimately also just a mathematical object in which we are embedded. So, in certain sense, we are universes in their own right.
