Session Abstract
The discovery that the universe's expansion is accelerating was not only unexpected, but it also led to the hunt for a mysterious Dark Energy that apparently comprises almost three-quarters of the "stuff" of the universe. How was this discovery made? What has been the progress since? And what does this tell us about how science – and scientific-style critical thinking – work?
