E8 theory

Just came across http://arxiv.org/abs/0711.0770 a theory of everything in which all of the stuff is incorporated into a single connection over spacetime.

This looks very appealing to me. I think I will try to understand this in the context of Bohmian mechanics and my own work on differential geometry as part of quantum stuff. The following quote from the paper intrigues me greatly:

The Riemannian geometry of general relativity has been subsumed by principal bundle geometry — a significant mathematical unification. Devotees of geometry should not despair at this development, as principal bundle geometry is even more natural than Riemannian geometry. A principal bundle with connection can be described purely in terms of a mapping between tangent vector fields (diffeomorphisms) on a manifold, without the ab initio introduction of a metric.

I love Riemannian geometry, but...

So on Friday 13, 2009, I did a major rewrite of the Bohmian mechanics page on wikipedia. It has been needed for a long time and now it is there. Now others can go in and refine it as the base has been dealt with. It is exciting and something the Bohmian community has wanted for a long time.

I am now thinking about what else it needs for acceptance. The main thing is to say that it applies to all current physics.

To that end, I want to create an article or a page that delves into a full theory based on QFT and relativity. My collaborators have already done the hard work. I just need to put together all of their pieces, and in some of my own flair, and hopefully the result will be the ability to claim that the Bohmian point of view works for the Standard Model. Maybe that will give good support for tackling quantum gravity, once all the cards are laid out on the table. The most difficult problem to tackle is understanding what the physicists have been talking about, as it is so couched in the language of experiments, i.e. measuring operators instead of the evolution of the wavefunction (which is present).

It will be fun.
