I came across a fairly interesting theory recently claiming that we probably don't live in the real world. The theory goes like this:
* Any sufficiently intelligent species will eventually be able to and will create complex simulations of reality. * Given the estimated final age of the universe, the chances are that such an intelligent species will come along at some point. * These simulations will eventually be cheap enough (in resource terms) to be run multiple times. * Given multiple simulations of reality are likely, the chances that what we see as reality is a simulation is very high.
The theory argues that if a species made 99 simulations, then the number of possible realities we could be in are 100 (the 99 fake simulations and the 1 real world). This gives us only a 1% chance of being in reality and a 99% chance of being in a simulation.
How would we ever know if this world is a simulation? If we can't tell, does it really matter if we are or not? Are we any less real by being in a simulation?
