Thomas Campbell has a Master's degree in physics from Purdue University and began his career working in the nuclear technology industry.  In the early 1970s, he began researching altered states of consciousness with Bob Monroe at the Monroe Institute in Virginia using basic scientific methodologies.  Campbell took what he experienced directly and learned from all of the experiments at the Institute and wrote the trilogy "My Big TOE" (TOE stands for "theory of everything"). 

 

According to him, "it represents the results and conclusions of thirty years of careful scientific exploration of the boundaries and contents of reality from both the physical and metaphysical viewpoints…By demanding high quality repeatable, empirical, evidential data to separate what's real (exists independently and externally) from what's imaginary or illusory; Campbell has scientifically derived this general model of reality."  Today, Thomas lectures on the nature of reality and also works as a scientific consultant in the US Defense industry.
