Conference: “The Expansion of the Universe: 100 Years of Einstein’s Cosmological Constant”

By Mathieu Langer, CNRS researcher at the Institute for Space Astrophysics
May 18, 2017, from 8:30 p.m. to 9:30 p.m.
Galileo Planetarium
In the modern sense of the term, cosmological science is still in its infancy. And yet, how many twists and turns there have been since its birth! I will take you on a guided tour of the history of the universe as we know it today, from its incredibly energetic beginnings to the present day of accelerated expansion. Along the way, we will see that the birth of cosmology is closely linked to the famous cosmological constant, which celebrates its 100th anniversary in 2017. Finally, we will open the door to the big scientific questions that are currently occupying cosmologists around the world.
