Un article paru dans Nature ces jours-ci sur les univers parallèles en mécanique quantique. (Théorie d'Everett)

There is also a global effort to build quantum computers which, if successful, will be able to factor numbers exponentially faster than classical computers, effectively performing parallel computations in Everett’s parallel worlds.

The choice is yours. But I worry that if we dismiss theories like Everett’s because we can’t observe everything or because they seem weird, we risk missing true breakthroughs, perpetuating our instinctive reluctance to expand our horizons.
