Avec la dA(c)couverte A(c)tonnante que l''univers se trouve A prA(c)sent dans une phase d''expansion accA(c)lA(c)rA(c)e, il y a dix ans, la cosmologie entra dans ce que l''on peut nommer l''A]re de la cosmologie A haute prA(c)cision. Les contraintes actuelles indiquent un modA]le cosmologique A gA(c)omA(c)trie plate, oA la plus grande partie du contenu en masse-A(c)nergie de l''univers est contribuA(c)e par une composante inconnue, souvent appelA(c)e l''''A(c)nergie noire''.

The work published by Einstein, Podolsky and Rosen (EPR) in 1935 is a classic in modern physics. It discusses, for the first time, the central feature of the quantum theory: entanglement. In general, systems are intertwined with each other in nature; that is, they have only one common, non-divisible state. This fact is responsible for all the oddities commonly associated with quantum theory, including the famous thought experiments with Schrödinger’s cat and Wigner’s friend. The entanglement of quantum mechanics plays a central role in experiments with atoms and photons (Nobel Prize 2012...
