Abstract:
Our understanding of the Universe at the most fundamental level is based on two seemingly radically different theories. Einstein’s General Relativity describes the gravitational force that governs physical processes on the largest possible scales. The revolutionary experimental discovery of gravitational waves, little ripples on the geometry of spaces and time, is the latest confirmation of Einstein’s theory. The other three forces in Nature, the electromagnetic, the strong and the weak force, are unified in a single framework known as Quantum Field Theory, which describes subatomic processes. The most important discovery in theoretical physics in the last 25 years is an exact equivalence between Quantum Field Theory in 1 time and 3 spatial dimensions, as in our Universe, and General Relativity… in one dimension higher! I will describe the basis of this correspondence, known as Holography, as well as applications to particle physics, cosmology and gravitational waves.
The ICREA colloquia are a great way to learn about remote fields of research from our best experts. They are open to all ICREAs and their guests.
