'''The [[Big Bang theory|big bang]] singularity''' or '''the cosmic singularity''' refers to a conjectured hypothetical 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
