Turns out it is all a dream, err, simulation: Physicists and proving the Matrix

2003. “Oxford professor Nick Bostrom suggested that we may be living in a computer simulation.” IO9 reports that now

Silas Beane and his team at the University of Bonn in Germany, [argue that] a simulation of the universe should still have constraints, no matter how powerful. These limitations, they argue, would be observed by the people within the simulation as a kind of constraint on physical processes.

So, how could we ever hope to identify these constraints? Easy: We just need build our own simulation of the universe and find out. And in fact, this is fairly close to what the physicists are actually trying to do. To that end, they’ve created an ultra-small version of the universe that’s down to the femto-scale (which is even smaller than the nano-scale).

Apparently, certain things that should behave one way will deviate and that deviation will be the clue.

OK this work seems quite wild. (study here if you like) But IO9 points out that this first step could lead to “more powerful versions in which molecules, cells, and even humans themselves might someday be generated. ” I am not sure whether these more powerful versions would be new simulated worlds or new things in the current simulation. Perhaps it is both. Ah another film nod! I rather liked the end of Men in Black when our blue marble that held a galaxy in it was part of another marble holding another galaxy and that was being thrown around when not stored in a bag. Even if we are in a simulation, as my friend John Scalzi said on a show about what happens if aliens show up here, we still have to take out the trash.
