True, all of the physical laws that are present at their maximum are highly symmetrical and ordered. Take, for example, Newton's physics and Einstein's energy-mass equivalence hypothesis. In a Newtonian mechanic’s certain law governs all kind of motion means certain order exist among the different system coming to icing theory. Where we found the youth success of science to understand nature which is the unification of space and time and unification of mass and energy.
This is true that underlying symmetry (or order Ness) in any process always attracts the attention of scientists. Because it is always easier to study the system which symmetry is because this, in turn, provides some form of conversation law by the help of Northers theorem this is true that if one gets the ordinance in any process either simple or Complex making some theory based on that is very easy and fruitful. Ordered means the fact that Earth moves around the sun in a well-ordered elliptical path for the motion of the ball falling under gravity is always a straight path which is also an ordered path.
Coming to the main part of our question which is the necessity of the existence of the order Ness. We want to mention that scientists want this Order Ness in the system but there is not only necessary that some Ordinance must exist. The introduction of quark in elementary particle physics was due to the observed asymmetric behavior among the different particles.
But initially, it was not supposed that any symmetry City must have to exist. Because if there is any proof for that then without observing any symmetric among the particles one can hypothesize the ordered behavior. So here ear is not any proof for that but ordinance and symmetry City always attract the attention. Also, from the entropy point of view, the system and the surrounding are whole have increasing randomness and decreasing order Ness. This means our system and surrounding is in some kind of otherness and slowly with time its order Ness decreases.
