There's been a lot of talk in recent years about the idea that our Universe—and all of our human experiences along with it—may be running entirely inside some sort of ultra-advanced computer simulation.
The implications of this idea are simultaneously profound and insignificant. Profound because it challenges our perception of reality and rewrites our thoughts on metaphysics; insignificant because it really changes nothing—our lives remain the same whether we do or don't live in a computer simulation (apart from any psychological turmoil that may result in pondering such a question).
But there's also an implication for how it could all end. What if the computer program upholding our Universe suddenly shuts down? What if, mid-sentence, someone closes the program without first hitting CTRL + S and all of our work is lost forever? We'd be effectively dead. Worse than that: erased, our entire Universe banished to non-existence.
This is what I'm referring to as "Death by CONTROL + ALT + DELETE." And to understand how this crazy idea could possibly make sense, follow along here as I attempt to summit this very challenging conceptual mountain.
