Double-Slit Experiment

Experimental Tests of the Role of Consciousness in the Physical World

Principal Investigator

Key Collaborators

This long-term, multi-phase project is exploring 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.
