About :

October 14, 2008 Tuesdays at the Espace des sciences with Etienne Klein, Physicist at the Atomic Energy Commission, Professor at the École Centrale, Doctor of Philosophy of Science. The possibility of time travel is regularly mentioned by science magazines, sometimes even by scientists themselves, and is the subject of many science fiction novels. We will first discuss the meaning that can be given to the expression "time travel", then we will explain what contemporary physics says about it.
