Indeed it is so. The rules that operate on our everyday level may not be broken or bent, or even folded, spindled, or mutilated, so far as we know. Of course, we now know that in specific other situations, entirely new sets of rules come into play, such as the situation of when someone or something is very, very, very small, or when someone or something is moving very, very, very quickly. There, Univ* has different sets of rules entirely, which may not correspond to the rules as we know them on our ordinary scale. In those situations, it may appear that the rules we are bound by in our everyday lives do not apply, but the new sets of rules are as ironclad and unbreakable as our ordinary everyday rules are.
And not only is the reminder of the consequences of the rules inexorable, it is swift - Univ* practices quick justice for those who test the rules. We are not simply told "Thou shalt not do something-or-other, or else something really bad will happen to you...in a few decades, after you die." No, if one should forget the rules dictating the acceleration due to gravity, and the rules governing the collisions of relatively inelastic bodies, while on top of that ladder, the reminder of those rules from Univ* will be immediate, severe, and inevitable. Forget the rules at your own peril...
