#### Re: If you knew SUSY like I know SUSY...

It's my opinion that even those most intimately familiar with these theories and the experiments don't understand them. At least not in the way you're trying to.

The thing is that when you get this deep into it, you can't explain or understand it in terms of familiar, everyday examples and analogies and if you try to then you get an imperfect picture which breaks down very quickly, leaving you more confused than when you started.

I think one of the finest (and most essential) talents of physicists is the ability to just trust the numbers without needing to 'understand' them in the traditional sense. In the end I think that's what all of this is - a bunch of numbers and equations. The numbers and the equations work (and work very well) but they don't do you and me much good.

That's not, in any way, to lessen the achievements of this field - quite the contrary. Humans just aren't equipped to understand these things 'properly' so we do what we can which is to understand the sub-atomic universe through mathematics. It's a spectacular testament that, even faced with an impossible task (the understanding of reality on a fundamental level,) these scientists persist anyway and in doing so, advance our knowledge and quality of life.

SO I suppose the upshot is to just not worry - no one understands these things in that way - if they did then they could explain it to the rest of us without having to use long strings of otherwise unintelligible words. Like this from the wikipedia article on something to do with String Theory:

"These conditions imply that the first integral Chern class c1(M) of M vanishes, but the converse is not true. The simplest examples where this happens are hyperelliptic surfaces, finite quotients of a complex torus of complex dimension 2, which have vanishing first integral Chern class but the canonical bundle is not trivial."

That's a part of a description of a mathematical concept (a 'Calabi–Yau manifold') used as a part of string theory and is in itself something that is impossible to visualise and with no acceptable real-world analogies. The fact that such a concept even exists and its mathematics understood and in use it as mind boggling and impressive to me as (theoretical) object itself.
