The interpretation of measurements in quantum mechanics has been disputed for over a century. The scope of this study is to find an experimental test of Everett’s many-worlds interpretation that could potentially verify the existence of a multiverse. Our proposal is based on a quantum field theory formulation of the many-worlds interpretation through the path integral formalism and a careful choice of the vacuum state. By generalizing the earlier quantum suicide thought experiment to quantum field theory, we find that the many-worlds interpretation implies a measurable change in the lifetime of elementary particles.
