There is a lot of wiggle room in quantum mechanics when it comes to how we perceive things compared to how they are. Minor changes in perception, or looking at a problem even slightly differently could make everything click. A big part of the problem with physics is that our observable universe isn't very observable. There are a lot of questions we just can't answer until we have the instruments to take measurements at Planck scales, and it's likely that, at those scales, everything that doesn't fit quite right will seem obvious, and everything that niggles at the back of a physicist's brain will be put to rest.
