RE: Upgrading nuclear and medical waste to dark matter detectors
Wouldn’t it be ironic if supersymmetry is somehow required to prove dark matter while simultaneously, dark matter is required to prove supersymmetry?
Like a physics deadlock. It would be exciting.
Many supersymmetric scenarios feature a dark matter candidate, but this is not a requirement. You have supersymmetric models without dark matter (called RPV supersymmetric models). Therefore, discovering supersymmetry does not mean discovering dark matter. Conversely, proving dark matter wrong will not kill supersymmetry, but only some incarnations of it.
On the dark matter side, supersymmetry is only one option amongst many, even if it is amongst the most popular ones.
To make it short: discovering supersymmetry and dark matter have implications on each other. But we cannot say more as dark matter may be supersymmetric or not and supersymmetry may feature dark matter or not.
