Mapping the Universe

I love Mekhi and Joe’s posts on physics on the blog Rationalising the Universe, which brings me more up to date on the enthusiasms for mathematics, physics and cosmology of my youth. But I had to take issue with the conclusion of the recent interesting post on What is a Field, which ended with the following statement:

There we have it, space is no longer a separate entity, space is a field and the universe now consists of fields and particles alone.

That’s exciting. Newton set the ball rolling on mathematical models of the universe, and the current mathematical model of the universe has now simplified to just fields and particles.

But look at the statement again. It says “the universe now consists of…”. Well actually it doesn’t, and I suggest that we still have little idea of ‘what the universe consists of’. But we do have a great model that explains what we see and can measure in a reasonably consistent manner.

The point is

“The map is not the territory”

Alfred Korzybski, 1931
