About this Unit

This unit begins with a detailed, mathematical treatment of Einstein's special theory of relativity and its implications for observational astronomy. These include apparent superluminal motion in the jets of active galactic nuclei, Doppler boosting, stellar aberration and so on. This leads into a qualitative description of the structure of space-time and Einstein's general theory of relativity. Basic concepts such as the space-time metric and its curvature in the presence of mass or energy are introduced, but detailed mathematical details are left for 4th year units. Various cosmological concepts are discussed, including how the ultimate fate of the universe is linked to its energy density. Current models of the evolution of the universe are explored, including the idea of an inflationary period shortly after the big bang. Observational measurements of the rate of expansion of the universe throughout its history are discussed, including recent evidence that suggests the rate of expansion is accelerating.Sources of uncertainty in these data are also considered.
