Theoretical physicist from Vienna, Austria. My focus is the theory of strong interactions and its study via the AdS/CFT correspondence, but I am also interested in aspects of general relativity, particle physics and string theory not related to holography.

comment Does a moving object really shrink due to length contraction?
I was the one who downvoted, but it was due to a mistake on my side (I misinterpreted something). I also noticed it almost immediately but could not undo my downvote (which I have now corrected). No politics involved. ;)

@innisfree Comparing it to QCD itself is also of great relevance, but since the question is about experiment, I did not go into that. Furthermore, holographic duals can make predictions where QCD itself fails, i.e. in a low energy regime where it is strongly coupled.

comment has AdS/CFT any predictive power in the natural context?
Could you please provide a reference for your statement about falsification?

comment Is it possible to have the principle of least action and multiple solutions?
@AlexanderMorton: No, the Euler-Lagrange equations are unique for a given Lagrangian. There might, however be an ambiguity if one encounters boundary terms. The latter can vanish for different choices of boundary conditions. An example can be found in string theory, where the choice of boundary conditions determines whether you are dealing with an open or a closed string.

comment Why do fermions come in generations, but not bosons?
The symmetry argument holds true for gauge bosons. To my understanding, there would be as many generations of superpartners as there are for quarks and leptons.
