The Science of Can and Can’t
From a young British scientist, a groundbreaking exploration of a radically different approach to physics
There is a vast class of things that science has so far almost entirely neglected. They are central to the understanding of physical reality both at an everyday level and at the level of the most fundamental phenomena in physics, yet have traditionally been assumed to be impossible to incorporate into fundamental scientific explanations. They are facts not about what is-the actual-but about what could be: counterfactuals.
According to physicist Chiara Marletto, laws about things being possible or impossible may generate an alternative way of providing explanations. This fascinating, far-reaching approach holds promise for revolutionizing the way fundamental physics is formulated, but also for providing essential tools to face existing technological challenges, from delivering the next generation of information-processing devices, beyond the…
