I am a graduate student studying astrophysics at Princeton. I received my bachelor's in physics and mathematics from Caltech (2011).

My primary interest is in general relativistic magnetohydrodynamics simulations of black hole accretion.

comment Tensors, indices and matrix notation - is there a common convention?
This is a good question that too many authors neglect to clarify. For my own part I always intend for the first index to index rows, and I never stack indices vertically except maybe on $\delta$, but I can't say for sure this is universal.

comment Certain doubts regarding the movie 'Interstellar'
GRRR. Why does everyone think Interstellar is some sort of documentary?! It is nothing of the sort, nor did it ever claim to be. The movie was meant to entertain. It was meant to explore the human condition, specifically its relation with science. It was not meant to provide any scientific facts, and indeed there was no hard science to be found in it. If you're looking for scientific interpretation, then you have completely missed what the director was trying to convey.

comment What defines a unit system and how many constants can we set to 1?
Note that you are describing the preferred unit system of relativistic astrophysics (Gaussian CGS + $c=1$), and that it forces $\mu_0$ to be dimensionless $4\pi$. Often too this $4\pi$ is absorbed into a redefinition of the units of electric/magnetic fields (the two being the same in this system), making it disappear from some equations but appear in others.
