Digitized Spacetime
For years now I've been quietly obsessed with Digital Physics, and the work of such great thinkers as Konrad Zuse and Edward Fredkin. Over Christmas, I decided to start getting the experiments of my own that I've carried out in this field into some kind of shape. So this is me committing at least some small part of my work to the web. Hopefully more will follow.

The video link below shows the action of a simple algorithm that I crafted. The idea is to illustrate that it is possible to replicate some of the behavior seen in quantum mechanical systems without resorting to statistical methods, or even physics dependent on continuous mathematics.

At the start of the video, the 'particle' is distributed randomly throughout a closed box containing a network of randomly linked nodes. Over successive iterations of the algorithm, the particle automatically coheres itself into a single body and takes on the property of straight-line motion, even though the network it traverses contains no straight lines. When obstructed by distortions in the network, it occasionally bifurcates, appearing in two places at once until the pull of the algorithm forces it to re-cohere to a single location.

It's my hope to use methods like this to replicate the two-slits experiment in a totally quantized system, and illustrate that what we see as rigidly uncertain behavior enforced by Heisenberg's principle can arise out of computation. There is a cost, of course, we must be prepared to adapt a few of our more cherished physical concepts, such as the definition of locality.

But more on that later, presuming I get round to it.

have you written a paper or posted anything with specifics about the algorithm?

I had the pleasure of working with Ed Fredkin at CMU a few years ago. He's presently teaching a course in Pittsburgh, including a CA algorithm we developed.

you can contact me at danbmil99 at yahoo
