Quote:*How old is our universe?* This is one of the most fundamental questions in cosmology, and we thought we had the answer: about 13.8 billion years. But what if we are wrong? What if our universe is twice as old as we thought, and that changes everything we know about its history and evolution? In this video, we will explore a shocking new discovery that suggests that our universe is 27 billion years old, and what it means for our understanding of the cosmos. We will also look at some of the mysteries and puzzles that led scientists to question the age of the universe in the first place, and how they used a new model to solve them. We will talk about how the James Webb Space Telescope has discovered early galaxies that seem to be far too advanced for their age, and how this challenges our theories about the origin and evolution of galaxies. We will also discuss how this new study can affect some of the fundamental questions and mysteries that we have about the universe, such as what happened before the Big Bang, what is the shape and size of the universe, and what is the destiny and fate of the universe. This video is based on a new study by Rajendra Gupta, a physicist from the University of Ottawa, who claims that our universe is not 13.8 billion years old, but 27 billion years old. His study is published in Physical Review D in November 2021.
