Buddhism and Cosmology

What are the consequences of the concept of interdependence on cosmological ideas in Buddhism? The concept of interdependence implies that the elements of the conventional reality we are all familiar with do not possess an existence that is permanent and autonomous. This thing exists because something else exists, that happens because this has occurred. Nothing can exist by itself and be its own cause.
Everything depends on everything else. Suppose that there is an entity that exists independently of all the others. This implies that it is not produced by a cause, that is, either it has always existed or it does not exist at all. Such an entity will be unchanging since it cannot act on others and others cannot act on it. The world of phenomena could not function. Thus interdependence is essential for phenomena to manifest themselves.
Because the concept of interdependence implies that nothing can exist by itself and be its own cause, it goes against the idea of a creative principle, a First Cause or a God that is permanent, all-powerful, that has no other cause than itself, and which created the universe. In the same vein, Buddhism rejects the idea that the universe can be born out of nothing - a creation ex-nihilo - because the universe has to depend on something else to emerge. If the universe was created, it is because there was a potentiality already present. The coming into being of the universe is merely the realization of that potentiality. One can thus interpret the Big Bang as the manifestation of the phenomenal world emerging from an infinite potentiality already in existence. In a poetic language, Buddhism speaks about of "particles of space" which carry in them the potentiality of matter. This is strongly reminiscent of the vacuum filled with energy that is thought to have given birth the material content of the universe in the modern Big Bang theory. Material phenomenon and things are not "created" in the sense that they go from a state of non-existence to one of existence. Rather they go from an unrealized state to a realized state. Once it has come into existence, the universe goes through a series of cycles, each composed of 4 stages: birth, evolution, death and a state where the universe is pure potentiality but has not manifested yet itself. This cyclic universe has no beginning nor an end.
