Quote from: Marek Zbik on April 15, 2024, 00:54:53The universe and its nature are very difficult to comprehend by the human mind which is adapted to solve problems of everyday life. Concepts such as singularity or Big Bang are metaphors coined to imagine abstractions of the universe that would otherwise be impossible to comprehend. Those terms do not constitute canons of faith in science but help us to understand the nature of the universe's reality. There are many models of the universe which may differ from each other in many ways. The singularity theorems that Stephen Hosking and Roger Penrose used as a metaphor for the beginning of time to predict how the universe should emerge were used in some models. It closely relates to the black hole visualization.
