→The big bang singularity: stylistics; emphasis; hot big bang singularity
== The big bang singularity ==
== The big bang singularity ==
'''The [[Big Bang theory|big bang]] singularity''' or '''the cosmic singularity''' refers to a conjectured state at the beginning of the universe in which material particles were at no distance from one another and the temperature, density, and curvature of the universe were infinite. The inference to this state is based on the evidence that the universe is expanding and thus it has established a clear path into the past. If expanding things (the large scale structure of the universe) are now far apart, they must at one point have been close together. At the singularity itself, a great many physical parameters zoom to infinity. This posts however a great problem for attempts for naturalistic explanations of the beginning of the universe since as the astronomer Joseph Silk observed, an indefinitely dense universe is where the laws of physics, and even space and time, break down.<ref name="Devils">{{Cite book

Many naturalistic scientists are trying to escape the inescapable fact that the universe really did begin by proposing speculative theories including imaginary time (cf. Hawking:"Only if we could picture the universe in terms of ''imaginary time'' would there be no singularities...When we go back to the real time in which we live, however, there will still be singularities")<ref name="Hawking">{{cite book

Joseph Silk: Maybe long before inflation there was a Universe that was collapsing near a singularity, which then inflated again, so there was already a history before the Big Bang. Some people think there was a 'pre-Big Bang'. One possibility is that this pre-Big Bang, if there was such a place, would have made lots of entropy (the amount of disorder in the Universe). And the Universe we live in does have huge amounts of entropy. That's one theory. But we have no understanding of how to change from collapsing to expanding. There's no physical way to explain that transition. Some people believe that they have explanations the pre-Big Bang, so it's a respectable theory.}}</ref> (cf.

== The hot big bang singularity ==
The big bang singularity is sometimes named '''the ''hot'' big bang singularity''' to emphasize the fact <ref name="WhomadeGod"/> that while going back in the time towards the origin of the universe, all matter and ''energy'' in the universe gets squeezed together into a "pinhead" - a process that would make it "very, very, very ''hot''".<ref name="WhomadeGod"/> Hot Big Bang singularity appears to be in violation of [[The First Law of Thermodynamics|the first law of thermodynamics]] since the global energy needed to run universe has come from nowhere and the principles of nineteenth-century physics require that energy is neither created nor destroyed. Thus, the hot Big Bang singularity remains beyond any [[cause and effect|causal]] scheme and the creation of the universe is still unexplained by any force, field, power, potency, influence or instrumentality known to physics or humankind.<ref name="DeniableDarwin/">
