Ah I see that now. Thats just the number of independent components (polarizations) of an (p+1)-antisymmetric tensor in (d-2) transverse dimensions i.e. (d-2) C _(p+1) = (d-2)!/(p+1)!(d-p-3)! while the massive case you can have longitudinal modes so you count the number of components of an...

If you recall that in 4d for the photon only 2 transverse modes which can be picturized to be the left and right circularly polarized. For d-dimensions there are d-2 transverse directions and so according to me the number of degrees of freedom i.e. the number of helicities ought to be 2 * (no...

There is no paradox at all. If two operators as you say are localized at timelike separated points (A is to the past of B let's say) then A*B term in the commutator cannot be interpreted "measuring B and THEN measuring A" for obvious reasons that once can never "measure" B (which is located to...

Not the formation of the horizon itself but the fact that due to Hawking evaporation of the BH, horizon dissappears at some late time and with it the information about the material which collapsed to give rise to the BH in the first place is gone without a trace.

Couple of things I'd like to point out (unless you've figured it out by yourself) 1) The P-L (pseudo) tensor is constructed in a manner so that it receives NO contribution from orbital ang. mom. since that can take any arbitrarily large/small integer multiple of h-bar while spin ang. mom. is a...

Thats part of the problem, but the major problem seems to even away from diverging curvatures/singularities just the presence of event horizons (where space-time is smooth and regular) information/unitarity appears to be lost which is in direct contradiction with Quantum Mechanics. So a complete...
