There are two more extreme taboos in relativistic physics these days.
1. The salary of relativistic quantum physicists. Nobody talks about that. Those who have, are no longer talking about not only not the salaries, but about not anything else, either. (I got lost in the negatives... somebody right me, please.)
2. The sex life of nuclear physicists. These are a bunch of rabbit-like creatures, who fornicate with gusto. The Hardon Collider was built by duping the public to donate billions for the project, while all it did was stimulate the pituitary gland of advanced physicists via psycho- and physiological suggestions.
3. The math of the inner child in all of us.
