Explore advanced tests of Einstein's General Relativity theory through two groundbreaking space-based missions in this comprehensive lecture by Professor Philippe Jetzer from the University of Zurich. Delve into the scientific capabilities and methodologies of LISA (Laser Interferometer Space Antenna), a revolutionary gravitational wave detector designed to operate in space, and ACES (Atomic Clock Ensemble in Space), a precision timekeeping experiment aboard the International Space Station. Learn how these cutting-edge space missions will enable unprecedented precision tests of fundamental physics, including measurements of gravitational redshift, time dilation effects, and the detection of gravitational waves from massive cosmic events. Discover the technical challenges and innovative solutions required to conduct these experiments in the harsh environment of space, and understand how these missions will push the boundaries of our understanding of spacetime, gravity, and the fundamental structure of the universe. Gain insights into the expected scientific outcomes and how these experiments will either confirm Einstein's predictions with extraordinary precision or potentially reveal new physics beyond General Relativity.
