“The discovery of supersymmetry would give string theory a big boost,” says Ed Witten ’71, a theoretical physicist at Princeton University, and one of the world’s leading experts on string theory.
Not all physicists agree with this assessment, however. “I think you’ll find that experimentalists and theorists have slightly different views on what constitutes ‘evidence,’” says Bensinger. “I’m an experimentalist. I want a real prediction that I can test, not just ‘Oh, I’ve observed something that’s needed by a particular theory.’”

... ou pour les modèles physiques basés sur la géométrie non commutative ? / ... or for the physical models based on noncommutative geometry ?
A. Connes : If supersymmetry is going to be found, it will be very hard to convince the physicists of the noncommutative geometry approach.”
Interviewer : But there is no contradiction between supersymmetry and noncommutative geometry.
A. Connes : “You are right, but string theory would claim the ground even more than they are already doing now. In any case, the Standard Model [of elementary particle physics] is full of tricks. What we need is simplicity. I think that is what noncommutative geometry provides. The inverse line element is an operator. Its only invariants [under unitary transformations] are the eigenvalues. And these are eventually what is observed in Nature. The truth is that this simplicity is only a starting point and a lot more work would be needed to explore the quantum theory.”

Et si ce débat autour de la supersymétrie n'était qu'un épiphénomène pour les sciences empiriques ?
What if the debate about supersymmetry was not a real concern for empirical sciences ?
