The Buddha declared, that an absolute beginning of things can not be found,…yet in regard to the phenomenal world, whether on a grand scale or in the very tiny things, all things are understood to posses these two sides of a spectrum, one being the beginning and the other being the end. Between these two points (or poles) there will be a space, large or small. And whatever thing (or phenomena) it is, whose beginning is considered, it will undergo change until it reaches its end(ing).

The immaterial, dynamic aspect that causes change to occur in regard to a universe and in regard to the coarsest inanimate forms of matter, in Buddhism is called Utu Niyāma, the law of generation or the law of physical nature. It is the law, that governs the arising, evolution and dissolution of the physical universe.

Energy, mass, movement and cohesion , …these are the first primary qualities of matter.

As these primary qualities become balanced and begin to work in the direction of synthesis (sampayutta) rather than being repelled by each other (vippayutta), they allow for the crystallisation of concrete matter. Thus tiny particles of matter evolve. These, following the trend of synthesis slowly combine into more durable structures. And so the foundations (nissaya) of matter are laid out.

As these basic forms of matter spread out, they form the entirety of the physical universe. Stars, suns, planets and the myriad varieties of matter that will form the surface and structure of the planets, slowly establish themselves.

Gems and crystals, mountains and valleys, surrounded by oceans and filled with rivers, are blown at by winds weak or strong and on occasions disrupted by fires from below.

Gradually matter becomes more and more refined and more specialised forms of matter evolve.

And when under the rule of this Law of Utu material evolves, that is more light, malleable and better structured, than it starts giving way to the next Law which is higher in order.
