It is difficult to single out a specific contemporary physicist who can achieve the unification you mentioned and become the next great physicist since Newton. The task of unifying macro and micro quantum theories is a complex and challenging endeavor that requires expertise in various fields of physics, including quantum mechanics, particle physics, and theoretical physics.
In the field of theoretical physics, there are many accomplished physicists who have made significant contributions to our understanding of the universe. However, predicting who will achieve a major breakthrough or become the next great physicist is highly speculative. Scientific progress often involves collaboration and the collective efforts of many researchers over time.
Prominent physicists who have made notable contributions in areas relevant to unification and the foundations of physics include:
Stephen Hawking: Known for his work on black holes, Hawking made significant contributions to the field of theoretical physics, including the discovery of Hawking radiation. His research explored the intersection of general relativity and quantum mechanics.
Lisa Randall: A theoretical physicist specializing in particle physics and cosmology, Randall has contributed to the field of extra dimensions and the concept of a warped spacetime in the context of string theory.
Juan Maldacena: Maldacena is known for his work on the AdS/CFT correspondence, which provides insights into the connections between quantum field theory and gravity. His research has bridged the gap between different branches of physics.
It's important to note that the unification of macro and micro quantum theories is an ongoing area of research, and it may require the collective efforts of many physicists over time to achieve significant progress. Additionally, advancements in physics often build upon the work of numerous researchers, rather than being solely attributed to an individual.
In summary, while there are many accomplished contemporary physicists, it is challenging to predict who will achieve the unification you mentioned and become the next great physicist since Newton. The progress of scientific discovery is a collaborative and evolving process that involves the contributions of many researchers.
