Is Our Universe a Fake?
... Robert Lawrence Kuhn ... "... speaking with scientists and philosophers on "Closer to Truth," I realized that the notion that everything humans see and know is a gigantic computer game of sorts, the creation of supersmart hackers existing somewhere else, is not a joke. Exploring a "whole-world simulation," I discovered, is a deep probe of reality.
David Brin, sci-fi writer and space scientist, relates the Chinese parable of an emperor dreaming that he was a butterfly dreaming that he was an emperor. In contemporary versions, Brin said, it may be the year 2050 and people are living in a computer simulation of what life was like in the early 21st century — or it may be billions of years from now, and people are in a simulation of what primitive planets and people were once like.
Philosopher Nick Bostrom, director of the Future of Humanity Institute at Oxford University, describes a fake universe as a "richly detailed software simulation of people, including their historical predecessors, by a very technologically advanced civilization."
It's like the movie "The Matrix," Bostrom said, except that "instead of having brains in vats that are fed by sensory inputs from a simulator, the brains themselves would also be part of the simulation. It would be one big computer program simulating everything, including human brains down to neurons and synapses."
Bostrum is not saying that humanity is living in such a simulation. Rather, his "Simulation Argument" seeks to show that one of three possible scenarios must be true (assuming there are other intelligent civilizations):
1. All civilizations become extinct before becoming technologically mature;
2. All technologically mature civilizations lose interest in creating simulations;
3. Humanity is literally living in a computer simulation.
His point is that all cosmic civilizations either disappear (e.g., destroy themselves) before becoming technologically capable, or all decide not to generate whole-world simulations (e.g., decide such creations are not ethical, or get bored with them). The operative word is "all" — because if even one civilization anywhere in the cosmos could generate such simulations, then simulated worlds would multiply rapidly and almost certainly humanity would be in one.
As technology visionary Ray Kurzweil put it, "maybe our whole universe is a science experiment of some junior high school student in another universe." (Given how things are going, he jokes, she may not get a good grade.) ..."
