Abstract

This is a bit more physics oriented (but philosophically informed). I distinguish (again) the different meanings that we attribute to the words "space" and "time." And discuss what happens to these notions when we consider the quantum properties of gravity, namely the quantum property of physical geometry. I illustrate why and how loop quantum gravity gives a precise and well defined answer to these questions. (This is the theory on which I am working)
