Quantum Mechanics Meets Cosmology

This chapter explores the implications of quantum mechanics in cosmology, focusing on Bell inequality experiments and their local versus non-local interpretations. It discusses the potential for testing quantum principles in the early universe and examines key aspects like superposition, entanglement, and the uncertainty principle within quantum field theory. The chapter concludes with innovative ideas to improve the detection of the inflationary field's properties amidst the challenges posed by an expanding universe.
