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”

The mystery

Individual consciousness is undeniable.

The existence of other consciousnesses and the external world is the only sensible basis for living.

According to cosmologists, space-time began with a ‘big bang’ and things gradually evolved into increasing complexity. At some point life emerged, and eventually so did individual consciousness.

So what happened/ what was the cause of (or ‘before’) the ‘big bang’? Does the question have any meaning?

And it leads to the question what if life/ consciousness did not exist?And how could it have started?

At which point the brain hurts.

There is always a mystery at the heart of existence! Some call it God.
