So the only question would be, does the Dirac equation properly describe the original situation.

Well, I'm suspicious of things necessarily working the same on such different scales. I mean F = ma doesn't even hold together when you approach the speed of light.

I mean F = ma doesn't even hold together when you approach the speed of light. Actually, if you re-write a bit as F= d(mv)/dt is does. where d()/dt indicates the derivative (rate of change) with respect to time. mv indicates mass times velocity or momentum. At v< F=m*dv/dt and dv/dt is just accelleration, a. Thus F = ma is merely the low speed approximation to the proper equation, which is a bit more complicated since mass becomes a function of velocity.
