During the 1950s, physicist Hugh Everett studied the bizarre implications of quantum mechanics. He theorized when someone locates an electron, the world splits into multiple universes. The electron has a different position in each one. These worlds, each equally real, go on to develop their own futures. This idea in quantum mechanics is called the many-worlds interpretation.[ii] According to the model, each universe produces a multitude of new ones every quantum instant, each fragmenting again into another. The total amount of universes would be infinite. Contact with any of them is theoretically impossible, each realm separate and distinct from the other. The theory is becoming more popular among theoretical physicists.
An opposing theory to the existence of any other universe is the idea of biocentrism. Developed in 2008 by biologist Robert Lanza, it asserts there is one Universe and it exists because we are here to observe it.[iii] The theory suggests the Universe is a living organism, and everything throughout is connected at the quantum level. It relies on the double-slit experiment, which is substantiated by several different experiments.
Considering how this publication interprets multiple realities, reality in this Universe relying on the existence of conscious beings should have nothing to do with whether or not there is a multiverse. The double-slit observation can be interpreted as a reason why universes split into alternate realities. Biocentrism, on the other hand, demands existence relies on the conscious observer, and only one reality is destined to exist.
Many-world interpretations adhere to the idea of an infinite number of possibilities diverging for every microsecond of each atomic event. According to the uncertainty principle, these possible futures branch off and become different pasts for an infinite number of alternate realities, all originating from a single universal realm. The theory is akin to the once popular television show, Sliders, where Jerry O’Connell and his gang jump from one alternate Earth to another, each harboring its own history. If true, every split second of every event or action throughout the Universe would branch off into its own reality with a unique past and future. In one reality, Reagan was elected president and in another, Walter Mondale. The same would be true for each and every action or decision made by every single organism in the Universe. The many-worlds interpretation is different from parallel universes that harbor their own unique realm and set of environmental circumstances, in addition to their own set of branching alternate realities. If parallel universes exist, they do so independent of their parent universe. They are unique in every respect, and some may harbor truly bizarre realities.
