I'm a physics grad student just trying to figure out all this stuff like everyone else.

comment Why are all observable gauge theories not vector-like?
Are you asking (1) why every conceivable gauge theory is not vector-like? Or (2) why the standard model is not vector like? As for (1) I can certainly write down a vector-like gauge theory (QED). As for (2) talk to God.

comment What is Supersymmetry (SuSy)?
I would suggest splitting this into 3 separate questions, or at least breaking the symmetry breaking questions into a separate post. As it stands the post is not focused enough.

comment In what subfields and how far can the naive limit $c\rightarrow\infty$ of special relativity be carried?
Do you have an example where this fails in the usual framework? As far as I can tell you can always take the non-relativistic limit, as long as its appropriate. i.e. We can talk about velocity addition at speeds much lower than c and it's a reasonable thing to talk about, but there isn't any reasonable way to talk about a photon non-relativistically.

comment why is dark matter the best theory available to explain missing mass problems?
I think you would learn a lot to start by reading en.wikipedia.org/wiki/Dark_matter. Afterwards you might not think its not such an outlandish idea.

comment What keeps electrons in an atom from flying away or falling into the nucleus?
This is a good point, I wasn't sure how much background he had so I didn't want to go off an a tangent about normalizablity and boundary conditions etc.
