Langton's ants and our Grids

Who has not wondered at least once in his/her life how things work! Science and religions feed us with many ideas over time and still aren't we hungry? Langton's ants is a miniature model of our universe(or at least what we think is our universe). It consists of a universe full of black grids. A virtual ant is situated on one of the grids. This ant is the only living being of that universe. The ant follows three rules of 'nature'.
  1. Change the color of the square it is standing on- (if the square is black change it to red and if it is red change it to black)
  2. Now Walks Forward to the square in front of it
  3. If it is on a black square turn Left and if it is on red turn Right by 90 degrees.
http://www.youtube.com/watch?v=OeeJLrsC-MI&feature=related is a video demonstrating how it works.

The Ant initially followed a very random path and after making a big chaos it started making a 'highway' in a particular direction. That was continued indefinitely.

What can we learn from Langton's ants while making some comparisons to our universe? There are two things to notice. Langton didn't have an intension to create that ordered path. Secondly, All what the ant does is following the rules.
Whether the universe has a creator or not is not the problem we are going to discuss here. Let's have a few thoughts on how our world works. We do know that, in our universe objects, living beings and everything follow some rules. Those rules can be the rules of physics(physics is there because we have those rules), biology or you name it. They can be simple rules like "The survival of the fittest" or Freud's theory of Id, ego and super-ego. These rules may not be familiar to us and that's the main reason for which we are still trying to find them out by creating theories and trying to fill the gaps in our minds. So, we are just some Langton's ants who follow certain orders. If we are following those orders, it is so obvious from the example of the LAs that we will form some sort of patterns or chaos or even pattern from a chaos. So, what we are asked to do is to follow some orders and what we do is to try creating patterns. So, we can conclude two simple facts. 1. An intention to make this world as it is now is not necessary to make it in the way it is. 2. If we are following certain orders the world we live is possible.
If we assume that there are certain orders which governs all our actions, what is the significance of freewill? Do we possess freewill? The answer is 'need not'. Our universe can be a replica of a more complicated Langton's ant with much more complicated grids and many more rules and ants. At the same time it can be like a game of chess with no predicted ending and thousands of possible moves. In that case, freewill comes into play. Everything is depended on the patterns we see. Do there exist certain patterns or are they mere illusions? in both chess and LAs moves once done are done for ever. It can't be changed. So all we have to look for is to find out the patters we form, If there exist patters, we are just machines which can't control the destinies. Otherwise we are a group of small Gods.

  1. Don,nice reading on LA model. But what I think is that we can create the pattern we need and follow it but whatever pattern we choose it will lead to a defined position at the end.
