I'm not physics expert, but I think there may be a limit to what we can understand about the physical world. Especially when we get down to such small scales. However, I don't think this is because of limited lifespans. I've heard it said that string theory could never be scientifically tested in a traditional sense. People sometimes compare it to a religious philosophy because of this quality of untestability. Maybe the logic of the universe at the lowest levels are hidden from us. If the universe is a computer simulation then we almost certainly are not exposed to the underlying mechanisms of how it works at the lowest level. The fluid in a fluid simulation doesn't have access to the knowledge of how the computer on which it is running functions. The fluid is just information. That information is manipulated by the running program, but the code of the simulation is not built into the information representing the fluid. Maybe the matter in our universe exists in the same way, as information. Maybe the mechanics that drive the motion of the smallest particles are not exposed. I'm sure I'm not the only person to postulate on this. People have probably written very scientific papers on this very topic. I honestly don't know, but it's what my programmer brain leads me to believe.
