The absolute truth of our existence will likely never be discovered. Everything we learn leads to more questions. When our species learned that matter was made of things called atoms, it appeared that we were much closer to understanding the nature of our universe. Soon, however, we learned that atoms are made of quarks and that there are structures and events existing on an even smaller scale. How do we try to make sense of our existence when every answer seems to lead to more questions?
Scientists who make it their life’s work to advance our understanding of the cosmos play a creative role finding answers. They make theories; they use their imaginations. Having a “theory,” though, means that it needs to be tested. If there really is an answer to the nature of our existence how can we be sure that it is even POSSIBLE to test it? If it can’t be tested, then it isn’t science.
That’s where philosophy comes in to save the day. Philosopher Dr. Nick Bostrom offers his own creative proposal to the nature of our existence: We could all be living in a computer simulation. Though only one of an infinite number of possibilities, his idea sparks much discussion, debate, and creative endeavors by others. His clearest argument is based on the premise that eventually the human race will create a computer that is more powerful than all human brains combined. (He is not alone in making this assertion.) Eventually, he believes, we will be able to run computer simulations in such incredible detail that the inhabitants of this simulated place would simply understand their virtual environment as the universe--the only one they’ve ever known.
It is a compelling argument if you accept that humans will eventually be able to make such a simulation. In that case it seems rather likely that we are also simulated. If you would like an expanded view of Bostrom’s Simulation Argument I have posted three links.
