.
Theologians say that the universe has many traits "quotas." They mean that the phenomena has to be explained with reference to something else, with external causes of the universe. Certainly the existence of human beings, like almost everything that we can observe in the universe, is, in this sense, contingent. So there must have been an act of intelligent that you have selected the enormous variety of possible universes . It must have been, in some way "chosen" a universe, or a narrow range of universes. It is not illegal to consider that this selection may be located outside or beyond the domain of physics, in the space of metaphysics. So from a religious point of view we can say that this selection was made by God Most scientists do not like this explanation and claim that we should seek a mechanism for selecting completely internal to the universe.
Cosmologists today, however, they rely on the so-called "quantum physics" and try to make it reasonable to the theological idea of \u200b\u200bcreation out of nothing universe. Quantum physics is based on the so-called "uncertainty principle" by W. Heisenberg. This principle tells us that everything can be measured or observed is subject to spontaneous fluctuations: they can happen, that is, sudden changes for no reason. We can observe in the laboratory as the phenomenon of those who make things happen for no apparent reason. For example, the decay of a radioactive nucleus is something that happens in a particular time for no reason apparent. We can not say why or in advance when the nucleus will decay, because what happens at a time rather than in another. In other words, quantum physics there is a unpredictability inherent in the nature. It thus becomes possible for the first time to conceive a universe that was born to a kind of quantum fluctuation: its origin is an event without a cause.
In pre-quantum physics was not allowed to have events without causes. Everything that happened in the universe had to have a definite antecedent cause, while in quantum physics you may produce events without a definite antecedent cause. If this event is the birth of the universe, it is no longer a problem for us: the universe was created just coming out of nowhere.
We must remember that already many centuries ago St. Augustine said that the world is born with the time and not in time. It 'worth noting that modern cosmological picture takes up this point of view. Today we know that space and time are part of the physical universe and are born with it. I want to express it this way: before Einstein was led to think about space and time as an arena in which it featured the great drama of nature. We sapppiamo now that space and time, in fact, belong to the "cast" of this drama: they themselves participate in the drama are actors in the great drama of nature that takes place in front of us.
You can not really talk about the birth of the subject without talking about the birth of space and time. The idea of \u200b\u200bthe birth of time is very original. It leads to a result: questions like "What happened first " big bang "?" Or "What caused the big bang?" Are meaningless, because there was a "before" , there was no antecedent cause as will the traditional physics.
Also, if time and space are elements of the universe, can be lengthened and shortened even in the laboratory. We can manipulate space and time in the same way we can manipulate matter. If they are part, to use a religious term, "creation", then it must have been created. I personally do not think there is no way to make sense of the world without supposing that space and time, in the "big bang", were created with the matter and energy originate.
