so, yes - you at least have to be in the same dimensionality as the system in which you're working - that's what I would assert. Since you're in 4-space, you should be in a 4-space basis set. Since, according to Cartan, Einstein (and NOT Minkowski, it appears), you should be in hyperbolics. Additionally, since the conformal projection of the null geodesic toward a "+H", if you will, or into conditional future in the light cone is path-dependent (for example, according to Weyl convention), then hyperbolic elliptical may offer the best "illumination", as Norman eloquently puts it.

It's quite complicated for me to understand the last post.

But another thing I do not understand is : sometimes it's said the singularity is a coordinate-singularity we used to describe space-time and not a singularity of space-time itself. Which then leads to the question to know if the singularity is real, what is reality in this context ?

Physics was parabolic and has become hyperbolic (hyper=a lot bolic=luck) whereas medicine is an elliptic science (ellipse=not saying=secret).

i did a quick look around for what happens to all that angular momentum from nuclear spin during black hole formation but i can't find anything (anything i can understand). do you know any overviews for newby's that include this?

 

I know that all such details get washed into a very few total quantities characterizing a gravitational collapse: mass, charge, angular momentum. The latter covers your particle spins and also the body dynamic rotations. Even though as a kid I "wanted to be a nuclear physicist", I don't yet know any condensed matter physics. I'm sure that there, spin combinations of hadrons are discussed.
