‘Could we ourselves be in such a computer simulation? Could what we think of as the universe be some sort of vault of heaven rather than the real thing?’
Martin Rees
 
       
  6. The Matrix in a Multiverse
Dr Nick Bostrom believes that we are about to enter the trans-human phase of our development. In decades to come, technology will take us into the realms of super-intelligence, perhaps by taking drugs, perhaps by surgical replacement of brain parts with silicon. The detail doesn’t matter, the principle does: life probably can supercede biological evolution and enhance its own intelligence.

‘We obviously can’t conceive of what a super-intelligence might be able to achieve any more than a dog can appreciate quantum mechanics,’ Martin Rees notes. But we can envisage that in a multiverse that contains an infinite ensemble of universes, there would almost certainly be intelligences that have evolved beyond are own, whether they have evolved biologically or technologically.

And if they are so very intelligent, these intelligences are bound to have asked themselves what the outcome would be if they could tinker with the laws of nature. They might have done some equations on paper first, but if their intelligence goes way beyond our own, they are also likely to have computers that go way beyond our own too – computers that could be used to discover the underlying law that allowed the laws of nature to be so precisely set as to create an exquisitely crafted home for life.

To test whether their discoveries are correct and their fine tuning is fine enough, they could use their super-computers to simulate a universe as complex as our own. Then they really have created The Matrix. And we really could be the inhabitants of a computer simulation. What this means is that we are just an elaborate experiment. We are not real.

But, let’s face it, that is what we still don’t know.
