Does Time exist? -- catchphrases and concepts

This paper lends perspective to the media catchphrase that <time does not exist>. To show how phrases such as this should be interpreted, we formulate some of the most important questions that arise in discussions about time in physics. We start by analyzing Newton&#39;s objective view on time and explain how entropy gives it a direction. After that, we discuss how relativity distances us from Newton&#39;s views, while quantum theory brings us closer to the Newtonian view. The arguments are presented in such a way that they can be followed and checked by anyone who studies the theories involved - be they undergraduate physics students or otherwise.
