The dark side of the Universe
The recent detection of gravitational waves represents a new era for science and an open window on our Universe. But what exactly do we know about the behaviour of our Universe and the structure of space on cosmological scales? This talk will take us on a journey to the extremities of the observable Universe in a quest to understand the behaviour of gravitation. The relationship between gravity and dark energy will also be discussed. Several observations have revealed the existence of the dark energy; they show that the universe is expanding faster than it should. Something powerful is opposing gravitation, something that physicists have called dark energy. Understanding the true nature of this energy and its relationship with gravitation should make it possible to develop a more precise understanding of the future of our Universe.
