Next Public Show — May 29, 2013
Topic:Light Years
Introduction:We've all heard that nothing can go faster than the speed of light, that the Sun is 150 million kilometres from Earth, and the Universe is 14 billion years old. The majority of us may not have heard how these values were determined. What stopwatch do we use to measure the age of the Universe, let alone the age of the Earth? What radar gun can we use to catch how fast light travels? And where do we store a 150 million kilometre measuring tape? This show will answer all of these questions, and more, regarding the nature of how distance, time and speed are measured in the Universe.
