What is the Two-Slit Experiment?





Back in 1803, Thomas Young, a London physician and physicist, proved something about light:  It was made of waves as well as particles.  His proof was based on the fact that when two separate wave patterns overlap, they don't simply blend, like different colors of paint.  Instead, they produce something known as an interference pattern.  There's nothing mysterious about that pattern.  It appears, for example, whenever you drop two stones close together in a pond.  Knowing this, Young set up his famous two-slit experiment.  Light from a point source is passed through a card or other opaque material containing two parallel slits, landing on a wall or screen on the other side.  If light were particles, one would expect the image of the two slits to project on the wall.  If light were waves, one would expect an “interference pattern" of alternating bright and dark lines.  The astounding result of the experiment is that one gets an interference pattern even if the photons are released one at a time!  A single photon should be able to go through only one of the two slits.  Yet it appears that a photon going through one of the slits “knows" of the existence of the other slit.

A thorough understanding of the two-slit experiment is essential to the comprehension of parallel universes, multiple realities and a “many worlds" interpretation of reality.

Recent discoveries in quantum physics (the study of the physics of sub-atomic particles) and in cosmology (the branch of astronomy that deals with the universe taken as a whole) shed new light on how mind interacts with matter.  These discoveries compel acceptance of the idea that there is far more than just one universe and that we constantly interact with many of these “hidden” universes.

Unfortunately, most books on quantum cosmology are written in language that an ordinary intelligent person cannot understand. 

What is needed is an understandable source that explains the concepts of the two-slit experiment, parallel universes, the many-worlds hypothesis, and their relationship to perceived reality––a source that brings together the contributions of such greats as:


Alain Aspect (the Aspect experiment)
John Stewart Bell (Bell's Theorem)
David Bohm
David Deutsch
Bryce DeWitt
Sir John Eccles
Albert Einstein
Hugh Everett
Stephen Hawking
Douglas Hofstadter
Fred Hoyle
Julian Jaynes
Sir James Jeans
Carl Jung
Subhash Kak
Sir Charles Lyell
Hermann Minkowski
Karl Pribram
Rupert Sheldrake
Neil Sloane
Karl Pribram
John Wheeler


What is needed is a source that makes clear the concept of the two-slit experiment, multiple reality, and the nature of the multiverse (or superuniverse).  Needed is a resource that explains in understandable, non-mathematical terms everything from Schrodinger's Cat to the big bang hypothesis to morphogenetic fields.

Such a source exists.
