I understand why you think so, since your species evolved with sensors that work at a particular macro level, and so intuitively you expect everything in reality to work the same way. It does not make sense to you that the same rules don't apply if you go really really fast, or if you're looking at something really really big or really really tiny, or if you're observing a process over a very short or very long time scale.
Sadly, this is a design flaw in your brain. You will not likely be able to rework your intuitions so that reality always "makes sense". Reality doesn't have to conform to your preconceptions, and your brain just isn't made to radically transform itself like that.
Luckily, you can choose to use a mechanism other than human intuition to understand the universe. Like mathematics, which seems to do a much better job, even in a way observable to humans. We have lots of devices (observable at human scales!) that do exactly what the mathematics said they would, like GPS.
But despair not! It's not completely a lost cause. Even though we are not made to understand things directly using math all the time, there are ways of retraining your intuitions to some extent, and correcting for your design flaws in other ways where that's not possible. Figuring out how to do that is the primary mission of this site.
I think there is a common miscommunication on this point. If something cannot be understood in the conventional human sense, can it be understood via math? It depends on what we mean by "understand." We can certainly catalog what we observe and summarize those data in the form of mathematical formulae and models.
However, if those are merely very succinct summaries, it is no surprise that they make accurate predictions, as they would effectively just be extrapolating from the observed data. It also seems unsatisfying to call that a theory in the traditional sense, if it is really more like curve-fitting.
