Conference : Can We Really Travel Into the Future?
21 novembre 2019 16:00 - Amphi Gaston Berger

There was once a time when we thought that time was the same for everyone. In 1905, Einstein published his theory on special relativity, a theory that would undermine our previous notions of space and time. In 1915, his general relativity radically shifted our understanding of gravitation, which became intimately linked to space-time. Through an analysis of science-fiction films, we will illustrate and explain revolutionary concepts that emerged more than a century ago. This will help us understand how these theories form the basis of satellite positioning and to what extent they may allow us to travel into the future.
