The Double Slit Experiment

In 1909 a British physicist by the name of Geoffrey Ingram Taylor proved that single photon can also act like waves. One of the initial experiments that sparked the ideas of quantum physics. This is the double slit experiment

What is the Double Slit Experiment?

To perform this experiment, scientists took a particle of matter called a photon. The idea was to shoot this photon at a target. Before the photon could reach the target it would pass through a barrier with a one slit opening. The scientists shot the photon at the target and it passed through the barrier and hit the target exactly as expected. The scientists were pleased with the results of the experiment as the photon / particle acted as they hypothesized it would.

Next they tried the experiment again, except this time they replaced the one slit barrier with a two slit barrier. This time when the particle was shot through the two slit barrier something interesting happened. The particle actually disappeared! When it reappeared the photon had reached the target but was no longer just a particle as it appeared in wave form and had passed through both of the slit openings at the same time. What this meant is the particle changed from a particle of matter into a wave of energy to accommodate the conditions of the newly formed experiment.

The conclusions from these experiments was that the consciousness of the scientists must have affected the outcome of the experiment. The fact that the scientists knew there were different openings affected the way that the particle worked. Similar experiments were conducted in 1927, 1961 and 1971 using electrons and produced similar results… That our consciousness has an effect on the world that we live in.

On February 26, 1998 this experiment was repeated again by the Weizmann Institute of Science in Israel. And once again this highly controlled experiment produced similar results. The scientists were able to demonstrate how a beam of electrons reacted to being observed. However the most shocking aspect of this experiment was that it revealed something unexpected. What it revealed was, the greater the amount of “watching” the greater the observer’s influence on what takes place.

The implications from these double slit experiments are quiet astounding. And I often wonder wonder what consciousness truly is, how it works, and what is its ultimate effect on this reality that we occupy. When reflection on such things I am reminded of the age old question… If a tree falls in the forest and no one is there to hear it, does it make a sound?
