报告摘要：The vacuum is essentially defined by the absence of what is known or believed to exist. As a consequence, the concept of vacuum and its possible existence have always been linked to fundamental questions in physics. We shall describe the evolution of ideas starting from the sixteenth century up to the beginning of twenty first century, from the discussion of falling bodies to dark matter and dark energy.
