Double-Slit Experiment

Arnaud Delorme, PhD, Dean Radin, PhD

Experimental Tests of the Role of Consciousness in the Physical World

Status: Complete

This long-term, multi-phase project explored the role of consciousness in shaping the nature of physical reality. Phase I successfully replicated a previously reported experiment investigating the role of observation on the amount of interference produced by a double-slit optical system. Phase II is investigating a similar hypothesis using a single-photon double-slit system. And Phase III is investigating new methodologies for conducting this type of experiment.

Co-investigator: Leena Michel

Key Collaborator(s): Robert Richenbach, Paul Wendland, James Johnston, Karla Galdamez
