When The Matrix came out in 1999, so many people walked out thinking "are we living in a computer program?" and it looks like physicists are thinking outside the square when it comes to our origins.
Nick Bostrom has hypothesized that the existence of our race could end up being nothing more than the algorithmic results of a computer simulation. It may sound a little nuts, but it sounds no less crazy than some theories given to use by not science and religion.
The best bit of this is that researchers have reached the point where they have a way that they can test this thought experiment. A team of scientists out of the University of Bonn in Germany suggest that even the most powerful Universe simulation would be subject to certain limitations of its host Universe.
These scientists believe they have a way to test if we're all just batteries for The Matrix:
The problem with all simulations is that the laws of physics, which appear continuous, have to be superimposed onto a discrete three dimensional lattice which advances in steps of time.
The question that Beane and co ask is whether the lattice spacing [example: our three dimensions + time] imposes any kind of limitation on the physical processes we see in the Universe. They examine, in particular, high energy processes, which probe smaller regions of space as they get more energetic.
What they find is interesting. They say that the lattice spacing imposes a fundamental limit on the energy that particles can have. That's because nothing can exist that is smaller than the lattice itself.
So if our cosmos is merely a simulation, there ought to be a cut off in the spectrum of high energy particles.
