It'll be interesting to find out what happens.

It's also like a toy model of QCD.

It has the same properties.

It's completely well-defined on the lattice, and then you can study what happens.

Now, this is very...

This in itself has a lot of potential, but we're just beginning to scratch the surface.

So there is a puzzle in basic physics, which is the separation of mass scales.

We've got the Planck mass, which is 10 to the 19 GV, huge number.

Then we have the weak scale, which is 100 GV.

That's the scale of weak physics.

We have strong interaction physics, a fraction of a GeV around a GeV.

So that's kind of particle physics scales or GeV scales.

And then we have the cosmological constant, which is, you know, down at a milli electron volt.

So essentially there are three widely disparate scales, and this is called the hierarchy problem.

Why does the law, why do the laws of nature have this ridiculous separation of scales?

Okay.

Now, imagine you have this theory, which is asymptotically free.

So in the ultraviolet, the coupling's weak.

I then ask my, and let's say we define the theory at very high energies where the coupling's, let's say, one-tenth, okay?

And then I think I know what I'm doing.
