As James Peebles pointed out in a conference after his Nobel Prize in 2019, the term \u00ab\u00a0Big Bang\u00a0\u00bb, which connotes a creation somewhere sometime, is a misleading term.<\/p>\n\n\n\n
In the standard cosmological model, Einstein’s equation defines a spacetime exhibiting a singularity (artefact or fact?) , which in the mathematical representation (manifold), is not part of this spacetime .<\/p>\n\n\n\n
Interpreting this as a creation of this spacetime is an anthropomorphic nonsense! <\/p>\n\n\n\n
A spacetime does not need to be localized in something which would define a time reference and a space container. The phenomenology of the universe can therefore be defined, only, by internal geometric properties of this spacetime. <\/p>\n\n\n\n
Thus expansion, for instance, is an internal property: The geodesics followed by the infinitesimal elements of the fluids filling the universe, all emerging from the vicinity of the singularity, diverge. It is an a phenomenology internal of the spacetime.<\/p>\n\n\n\n
So, the universe has neither creation, nor past, nor present, nor future and is not expanding, the only sensible problem is that of its existence<\/strong>. Because we are part of this universe and because we exist, the answer is a tautology: The universe exists.<\/p>\n\n\n\n One may interpret singularities as limits of the theory or even deffects of the theory.<\/p>\n\n\n\n Obviously, this is possible, but we should not discard that they just reflect the limits of what we may know on the physical world. <\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" As James Peebles pointed out in a conference after his Nobel Prize in 2019, the term \u00ab\u00a0Big Bang\u00a0\u00bb, which connotes a creation somewhere sometime, is a misleading term.
