Talk title: The Nature of Gravity & Spacetime in HUFT and Taiji Program for GWD in China

Abstract:I am going to talk about the recent progresses on the hyperunified field theory (HUFT) and Taiji program for the space-based gravitation wave detections in China. The focus is paid to the foundation of the HUFT based on the maximum entangled-qubits motion principle and gauge invariance principle, which enables us to understand the nature of gravity and spacetime, and meanwhile make issues on the long-standing open questions: what is made to be the fundamental building block of nature? What is acted as the fundamental interaction of nature? what brings about the fundamental symmetry of nature? how does Einstein’s general relativity arise from unified gauge field theory? what is the basic structure of spacetime? how many dimensions does spacetime have? what makes time difference from space? why is there only a single temporal dimension? why do we live in a universe with only 4D spacetime? Why are there leptons and quarks beyond one family? how does the fundamental symmetry govern basic forces? how does early universe get inflationary expansion? what is a dark matter candidate? what is the nature of dark energy? The space-based gravitational wave detections are expected to provide a new window in probing the gravitational universe and exploring the nature of gravity and spacetime.
