How did Pauli and Fermi deduce the existence of the neutrino?
It's all about spin. The conservation you mentioned is the key to it - you could conserve energy and/or momentum by tweaking the resulting KE, but you're still left with unconserved spin. Historical …

Beyond Standard Model
Yes, the point about (some) of the energy scales requiring "an accelerator the size of the galaxy" is serious. But only in certain cases, and assuming we stick with the same accelerator designs we cur …

How are subatomic particles affected by gravity?
What you're describing is partly impossible. You can't shield from the weak and strong forces, you'd be able to do some weird stuff if you could, like preventing radioactive decay and blowing protons …
