# Spacetime in Everett's interpretation of quantum mechanics

@article{Marchildon2017SpacetimeIE, title={Spacetime in Everett's interpretation of quantum mechanics}, author={Louis Marchildon}, journal={arXiv: Quantum Physics}, year={2017} }

Everett's interpretation of quantum mechanics was proposed to avoid problems inherent in the prevailing interpretational frame. It assumes that quantum mechanics can be applied to any system and that the state vector always evolves unitarily. It then claims that whenever an observable is measured, all possible results of the measurement exist. This assertion of multiplicity has been understood in many ways by proponents of Everett's theory. Here we shall illustrate how different views on… Expand
