The arguments put forth by Roger Penrose and Vlatko Vedral address different aspects of the nature of the universe and its origins. While they both touch upon concepts related to quantum theory and information, their perspectives and conclusions are not necessarily contradictory.
Roger Penrose, a renowned mathematical physicist, has proposed various ideas related to the nature of time, space, and the origins of the universe. He suggests that the universe may have existed in a previous aeon, or epoch, before the Big Bang, proposing a cyclic model of the universe without a distinct beginning.
On the other hand, Vlatko Vedral, a physicist known for his work in quantum information theory, explores the relationship between information and the fundamental nature of physical reality. His research suggests that spacetime could be emergent from the underlying information-processing activities of quantum systems.
While Penrose's ideas primarily focus on the nature of the universe as a whole, including its potential cyclic nature, Vedral's work emphasizes the role of information in the description of physical phenomena. It is worth noting that the concepts of spacetime emergence from quantum information are still a subject of ongoing research and debate within the scientific community.
In summary, Penrose's proposal and Vedral's quantum information theory address different aspects of the universe, and their ideas are not necessarily contradictory. The nature of the universe's beginnings and the relationship between information and spacetime are complex topics that are still being explored, and different perspectives contribute to our understanding of these fundamental questions.
