A curated collection of educational materials on the many-worlds interpretation (MWI) of quantum mechanics, maintained by Paul Razvan Berg. MWI is also known as Everettian quantum theory.
I spent years reading about this topic and I've collected the best entry and mid-level resources I've found here. I hope you find them useful.
MWI was first proposed by Hugh Everett in his 1957 PhD thesis, "Relative State" Formulation of Quantum Mechanics. If you're new to the MWI, I recommend starting with David Deutsch's content.
