I am a postdoc in mathematics, but have my degree in theoretical physics. My work is about mathematical structures motivated from quantum field theory and string theory. For more see my personal web on the nLab.

comment Is it expected tha all stellar black holes will be spinning near the maximum allowed $\omega$-velocity?
Nice comment, but for emphasis, let's notice that this is an argument in favor of the answer "yes, black holes will tend to have maximum angular momentum". Because that maximum angular momentum ("extremal Kerr black hole") is J=M^2, hence q=1. So under black hole formation a star may generally have more than this critical angular momentum and black hole formation sets in right at the critical value.

comment Why aren't we Boltzmann brains in an infinite universe?
-1 for using the words "strong argument" in this context. All this is intellectually undisciplined speculation without any attempt to base arguments on science or logic.

comment How algebraic geometry and motives appears in physics?
For the appearance of motivic Galois groups in perturbative quantization see Connes-Marcolli's textbook ncatlab.org/nlab/show/… . For the appearance of generalized pure motives in higher geometric quantization see this thesis: ncatlab.org/schreiber/show/master+thesis+Nuiten .
