In this article Oxford Physicist Chiara Marletto explores whether we should consider information, rather than matter as the fundamental building block of the universe.
Information has come to play an increasingly fundamental role in our lives during the last few decades: billions of computers are now interconnected over the world, and our technology – and hence our survival and well-being – crucially rely on them.
It is much harder to argue that information plays a role in fundamental physics.
Traditionally, fundamental physics expresses predictions about where, say, a particle will go, given its initial state and its laws of motion. This paradigm has been the prevailing one since Galileo and Newton and has been extremely successful – allowing us to formulate deeper and deeper explanations of the physical world, of which quantum theory and general relativity are the current best examples. Yet, there are things in the physical world that this mode of explanation cannot adequately capture for us.… Read the rest
