Does quantum mechanics actually require the existence of parallel worlds?
In short: Chiara Marletto explores why the Many-Worlds interpretation has gained such significant traction among physicists. She examines whether our universe truly branches into countless realities or if this framework offers a more elegant way to understand quantum theory.
The Many-Worlds interpretation is increasingly attractive because it applies quantum theory universally. Unlike other models, it avoids the need for 'wave function collapse'—the idea that a quantum system suddenly settles into one state upon observation—and does not require introducing extra assumptions to explain reality.
Marletto, a Research Fellow at the University of Oxford, uses her expertise in theoretical physics to contextualize this debate. The discussion matters because it touches on the fundamental nature of existence and whether our mathematical descriptions of the universe are literal maps or mere approximations.
