The universe as simulation
I've been doing a bit of research into time and its relation to quantum information processing, and found something that is at once disturbing and liberating.
It seems we are likely living within a simulated version of reality, and the proof of this is relatively simple. Imagine we are the sole proprietors of time, living in our multiverse (or universe, depending on your chosen interpretation of quantum mechanics - it really doesn't matter since the result comes out the same). I hope this isn't hard to do, since it certainly seems that we are living in the only system. Now, imagine millions and millions of years in the future when we have reached the point where we have mastered all the cosmic forces in the universe and have immense computing power at our disposal. Within the confines of our own universe, we would have the ability to simulate thousands of other universes at various points in time.
Now, these distant versions of us in the future have millions of simulated versions of us at various points in history. What are the chances, do you suppose, of us living in one of those highly advanced simulations? In fact, the chances are slim to none that we are the original version. What does this mean? Absolutely nothing. Our universe is the same as the original, and we are free to create our own simulations within the simulation.
Furthermore, simulation is an improper term. Since we are probably only the future imagining of our former selves, there is no true reality save for the reality we know. We will one day go on to create other imaginings of ourselves, and other simulations with radically different properties. That is our gift to ourselves, one might say. We are anything but trapped, no matter whether we are the original or the copy, since we have all the possibilities available to ourselves if there is an original us. In this respect, we will one day be able to escape our universe by diving into the simulations of our own creation. Going deeper into recursively simulated versions, we would be gods in the machine. However, once inside you can never escape to a "higher" simulation.
Heh, put that in your pipe and smoke it.
