The Double Slit Experiment is an experiment in Quantum Physics that shows a mind-altering view of the world and how we affect it. The Double Slit Experiment was voted the most beautiful experiment by the readers of PhysicsWorld. I'm going to explain everything as easily as possible so that you won't get discouraged during this explanation, so open your mind and be ready for a strange ride. First of all, let's explain what Quantum Physics is. Quantum Physics, simply put, is a type of physics of the atomic and subatomic levels which means it's the study of the very, very small. Normal physics do not apply at this level. Heck, there's nothing that seems normal that applys at this level. For example, remember in school when they taught you that electrons, protons, and neutrons were tiny balls of matter. Even that is not always true. What? They taught us lies? No, they were teaching you in just a way that your young mind could have some kind of explanation of what is down there at that level. The electron is not really matter as we know it anyway, its just a cloud of energy. Ok, that's somewhat believable so far. Here is where you'll have to choke down some faith. Electrons, protons, neutrons are popping in and out of existence constantly. Scientist don't know why, they don't know where they go. They just know they do. No, don't click off this page! This is not some quackpot writing this webpage. This is true science as far as our feeble minds can comprehend. It get even weirder with the Double Slit Experiment so stick around. To explain this experiment, we first must truly grasp the difference between what a particle is and what a wave is. A particle is what we perceive as matter of some sort - something with mass. A wave is a disturbance in some type of substance - i.e. water, air Ok, that's easy enough. Now, what if I told you that a subatomic particle isn't a particle until you observe it. What is it then? Its a wave. Huh? For some unknown reason that haunts scientists, everything we perceive as having mass is just a wave of information (or possibilities) until we observe it in some way. I'm not talking in the philosophical way like if a tree falls in the woods and no one's there to hear it, does it make a sound. The Double Slit Experiment seems to answer that question as you'll see later. Until we observe the soon to be particle, its a wave that's actually doing every possibility it could do at the same time. Huh?!?! It doesn't make any sense, yet this is one experiment that appears to somewhat prove this. The Double Slit Experiment shows us that we create reality just by observing it. WHOA, create reality?! Yes we do. If you still don't believe me, watch this movie excerpt from a movie called What the BLEEP!? Down the Rabbit Hole and make up your own mind.
Has this changed your view of your old science class in school? The subatomic material will take every possible path at the same time as a wave when not observed. When observed, the particle collapses down to one point as a particle. What can this mean about us? Do we all have powers that we are not aware of? The biggest question is can we change our reality? These are other questions that some scientists are afraid to talk about, but if we cause particles to exist by observing them, then we seem to create reality. Most scientists will tell you that we don't have any control of how we create reality as they are afraid of backlash from the scientific community if they start believing in spooky unknowns. Some scientists will say that we can create our own reality and have their own theories to back it up. I'm not here to say either side is right. I just love this experiment and the debates that it brings to us. Two movies that dwell on this question are:
