Our universe spawned into existence about 13.7 billion years ago. The Big Bang is the prevailing cosmological model explaining the existence of the observable universe from the earliest known periods through its subsequent large-scale evolution. It is also widely accepted as being the beginning of space and time. However, there is one problem with this grand idea. It cannot explain the big bang itself, or the conditions that created it.
Sir Roger Penrose is a British mathematician, mathematical physicist, philosopher of science and Nobel Laureate in Physics. He argues that the Big Bang was «not the beginning». There was something before the Big Bang and that something is what we will have in our future.
Cosmologists have made many presumptions and hypothesis that have looked deeply into these factors that include dark matter, dark energy, several inflationary cosmological models, and inflationary cosmology.
