Why should everything I can see right now be bigger than a nanometer, giving off electromagnetic radiation between 400-790 terahertz, not immediately fatal to humans and within the walls of this room? ...It seems like too much coincidence.

Why should every known behavior in physics be linear in quantum evolution, local in space and time, Charge-Parity-Time symmetrical, and conservative of probability density? ...It seems like too much coincidence.

Observation bias? Couldn't some alternative behaviors be vastly harder to for us conceptualize or detect or exist near, orders of magnitude less likely to be discovered? How can you know which apparently universal laws in physics just describe the low-hanging fruit? A good guide for finding the next discovery, but not true.
