Explore the origins of the Universe in this comprehensive lecture by Professor Geraint Lewis. Delve into the complexities of modern physics, examining the divide between Einstein's General Theory of Relativity and quantum mechanics. Learn about the historical development of our understanding of the cosmos, the challenges of unifying these two fundamental theories, and their applications in various research areas. Discover the processes of big bang nucleosynthesis, star formation, and element creation. Investigate the future of the universe, the nature of dead stars, and the intricacies of Hawking radiation. Gain insights into how scientists are working to bridge the gap in our knowledge and create a unified theory of the Universe.
