Ich bringe hier jetzt mal Niveau rein:
"A singularity is a region of space-time in which gravitational forces are so strong that even general relativity, the well-proven gravitational theory of Einstein, and the best theory we have for describing the structure of the universe, breaks down there. A singularity marks a point where the curvature of space-time is infinite, or, in other words, it possesses zero volume and infinite density. General relativity demands that singularities arise under two circumstances. First, a singularity must form during the creation of a black hole. When a very massive star reaches the end of its life, its core, which was previously held up by the pressure of the nuclear fusion that was taking place, collapses and all the matter in the core gets crushed out of existence at the singularity. Second, general relativity shows that under certain reasonable assumptions, an expanding universe like ours must have begun as a singularity."
"The geometry of the no-boundary universe would be similar to the geometry of the surface of a sphere, except it would have four dimensions instead of two. You can travel completely around Earth’s surface, for instance, without ever running into an edge. In this analogy, unfolding in imaginary time, Earth’s North Pole represents the Big Bang, marking the start of the universe. (But just as the North Pole is not a singularity, neither is the Big Bang)."
"An extraordinary burst of expansion in the very early stages of the universe inflated the size of the cosmos by a factor of 1050. This contrasts with the standard big-bang model, which has the universe expanding at an ever-decreasing rate as gravity tries to pull all the matter back together."
