Is Theoretical Physics Progress Stagnating?

[cbd1]

Is it just me or have we had a lack of discoveries in our theoretical physics endeavors for some long time now?

e.g. No WIMPs or other 'dark matter' particles detected with all those detectors, no Higgs particle at the LHC, no LIGO gravitational waves detected, no proofs of String theory or Loop quantum gravity, or any headway towards quantum gravity otherwise. There has been no primordial black holes evaporating.. should I go on?

What do you make of this?

There has been much discovery in Theoretical Physics but not a lot of discoveries of theoretical ideas in experiments.

Actually, a negative result for a Higgs particle at the LHC would be a monumental revelation, somewhat akin to the null result for the luminiferous ether by the Michelson interferometer in the 19th century. Don't quit just because it might be a daunting task to progress the field.
