SUSY in Trouble?
The standard model of particle physics contains at least 20 free parameters, from particle masses to the speed of light. Finding a mathematical basis for these numbers has obsessed physicists for decades. SUSY hypothesised that each particle had a corresponding "superparticle." These superparticles conveniently have energies too great to be detected by our experiments. This turns the problem of 20 free parameters into hundreds. This is progress?
Like inflation and cosmic strings, there was no way to falsify the theory. For years SUSY provided employment to many theorists. It turned into a framework in which anyone could insert their own speculations. New accelerators are approaching the energies in which superparticles would be found. As experimental energies get higher, more SUSY theories may be falsified.
There is Trouble With Physics because theories like SUSY have not led to advances in our understanding. Funding and respect for physics is dropping along with job prospects for young researchers. In the meantime, out of the spotlight, progress is quietly being made. If the speed of light can be predicted, there is hope that someday we will find a mathematical basis for other numbers.
