The physical behavior of a horse is better understood than that of an electron and might make it easier to consider the subject at hand, though. We know what path the horse will travel and we know that when the horse reaches the barn, it will go splat (well, in this case the barn will go splat). There are several competing theories that could describe what happens with the electron and the exotic particle, though. Also, it's fun to picture a horse travelling at relatavistic speeds :)
