2019: Year in Physics Review Part 1 Beginning our countdown of the biggest stories of the year in physics, as chosen by quantum physicist Ian Durham.
An amped up version of the Schrodinger Cat Paradox spells trouble for all quantum interpretations -- according to its architect Renato Renner. He tells Zeeya and Brendan how the controversial thought experiment works, and why he thinks it is bad news for fans of Many Worlds and quantum parallel universes, QBism, Collapse models and (less so) for Bohmian interpretations of quantum mechanics. But not everyone agrees.
