Another Crack at Cosmology

Aug 04, 2010 Posted Under: cosmology

The last attempt at this discussion started with the Heisenberg Uncertainty Principle already in play. But that presupposes too much.

Instead, I’d like to take a common saying of my teenage son as a starting point: “Dad, I’m bored.” Now I think he is asking for coaching about how to discover more interesting things, which of course I could learn more about (the coaching — I’m already interested in many, many things).

But if one imagines, as many people do, that there must have been a “prime mover” who created this universe, It might have also said “I’m bored.” This might have lead to some imaginings.

Let us imagine a zero dimensional universe. But there would only be one point. Not very interesting. So, let us imagine a rule: it must change. If it changes, it might eventually become interesting, especially if the changes permit complexity to arise. So, we must imagine some changing rule or rules. I think this notion, of change, creates TIME.

One change might be: the number of dimensions of our universe. So, let us imagine a one dimensional universe. Now here we have some leeway. An infinity of points, infinitely close together, or infinitely far apart, however you like to say it. But all the points are zero dimensional — again boring. So what if we invent some ways of assigning attributes to subsets of the line universe. How about two points together can have a polarity, a north and south pole. Or each point has an address, a distance from an arbitrary middle point of the line. Or each point is only probably there.

Actually, the probability notion has some merit, in that quantum mechanics is immersed in it. What if the probability of a point’s existence is spread out over, say, 11 dimensions (adjacent points) like some string theories?

But there still is a big puzzle about how zero dimensional points can be mapped to a physical thing with actual size, like a Planck size. How can a point have an attribute? If it exists on a line segment, it could have a distance from each end of the line segment (except for the infinite number of points insertable between each pair of points). Or, if we imagine a line constructed from a rule like “each point makes a new neighbor point on its right or left, whichever has no neighbor”, there could be a number of points from the starting, middle point, an address so to speak.

I don’t yet have any clear idea where this is going, but I wanted to start as near the beginning as could be …
