| Video Discription | 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. According to Roger Penrose however, proposals for describing the initial state of the universe hardly ever address a certain fundamental conundrum — yet this is a conundrum whose significance is, in a certain sense, obvious. The issue arises from one of the most fundamental principles of physics: the Second Law of thermodynamics. According to the Second Law, roughly speaking, the entropy of the universe increases with time, where the term “entropy” refers to an appropriate measure of disorder. There are many popular theories among scientists that suggest that the Big Bang was not the beginning of our universe. The many-worlds interpretation which is one of many multiverse hypotheses in physics implies that there are very many universes, perhaps infinitely many. Roger Penrose argues that the idea of many worlds is flawed because it is based on an oversimple version of quantum mechanics that does not account for gravity. According to Penrose, "the rules must change when gravity is involved". However criticism has been levied towards several parts of Penrose's theory. Penrose himself has admitted that his model is extremely speculative. #penrose #universe #science SUBSCRIBE to our channel "Science Time": https://www.youtube.com/sciencetime24 SUPPORT us on Patreon: https://www.patreon.com/sciencetime BUY Science Time Merch: https://teespring.com/science-time-merch Sources: "File:Roger Penrose 9532.JPG" by Biswarup Ganguly is licensed under CC BY 3.0 London thinks - An intimate conversation with Roger Penrose at Connwey Hall https://youtu.be/3OsE8NETbNQ Gurzadyan, V.
