physical laws and the universe

Hello there,

Physics has a tradition of modeling things into mathematical
equivalents and then extrapolating the model to predict further
possibilities. We observe the motion of particles and formulate the
laws of motion. Now we use these laws to solve further problems
involving motion of particles.

This involves a sort of determinism, which is validated by observation,
that within the stated conditions the observed system is bound to obey
the rules which we formulated.

My doubt is, in a broader sense what makes sure of this. What makes
sure that everything always follows certain rules. Why the universe
doesnt evolve to be completely chaotic, without any specific laws. Or
simply, what makes sure that the universe always obey mathematical
models?

Is there any kind of memory?!

In a sense, the question I would like to raise is " why the universe is
like this?" It could have evolved in many other ways. What keeps it in
this way?

Please post your views and do let me know if I didnt express it
properly.

Cheers,
