There is a long-standing tradition of believing that our existence is only part of an even greater cosmos, and it’s still an idea that is continually challenged and pondered upon. After the Big Bang, it has only been 13.8 billion years, and the maximum speed at which all data can propagate is still finite (being the speed of light). The measurable Cosmos is small, even though the whole universe itself can truly be limitless. Despite this, the leading ideas of quantum physics and astrology suggest that our world could be only one negligible area of a much wider multiverse beyond which exists multiple worlds, perhaps even an unlimited amount. Some of this may be scientific truth – however, a whole lot of the concepts and conspiracies being thrown around are nothing but skeptically wild speculation and wishful thinking.
The ancient Greek polymath and philosopher Aristotle repeatedly claimed that only a single universe was necessary by reason. His opinion persisted until 1277, when Stephen Tempier, the medieval Bishop of Paris, proclaimed that certain philosophers must be expelled if they preached the opinion of Aristotle, for questioning the ability of God to construct as many worlds as he wished. Generations of confusion and speculation resulted from this. Some claimed that God was able to construct more dimensions, but perhaps chose not to; others claimed that a “plurality of worlds” included reality.
The revered astronomer Johannes Kepler, however, did not agree with this concept. The cosmos to him was a planetary system, not a series of parallel realms beyond our comprehension. “If they are not seen,” Kepler said, “they are not important to astronomy for this purpose.” Something more than what is observable, he argued, “is superfluous metaphysics,” a perspective strikingly analogous to the mindset of many people today towards the idea of the multiverse.
In reality, Kepler was incorrect. Subsequent observations of the Milky Way galaxies showed a multitude of constellations at considerable distances, congregating in a circular formation. The solar system had been speculated to be just a single one among many other “universes.” The cosmos has been reinterpreted once more, not just a series of rings circling our planet or a series of terrestrial bodies orbiting the sun, but instead a gigantic disk of galaxies surrounded by an empty void.
Edwin Hubble recorded evidence in 1924 that a few of the mysterious constellations, like Andromeda, were actually galaxies like islands as vast as the Milky Way. The modern concept of the cosmos has been established by Hubble as a rapidly expanding bubble inhabited by trillions upon trillions of these worlds. By the 1980s, the multiverse debate was resurrected in a novel manner, discussing a modern theory of how the cosmos came to be, termed “inflationary cosmology”. If a blast of extraordinarily massive development (inflation) accompanied the original big bang that launched our existence into being, the same inflationary phenomenon may have recurred in other areas of the universe. If the hypothesis of inflation turns out to be right, then that means that our observable reality is just one among an untold infinity of realms in the universe.
The fact that multiverse enthusiasts have traditionally been accurate throughout history does not necessarily mean that they will be correct again. However, multiverse critics are definitely incorrect to say that it’s not verifiable due to the idea that the multiverse concept is not scientific. The multiverse is not just a philosophy to be investigated, but instead, it is a forecast of other ideas that must be investigated. Indeed, inflationary cosmology has already undergone a range of studies but is not yet adequate enough to be unequivocally defined.
Today, the cosmos has a few things to it that are reasonably straightforward to understand, at least with modern research equipment. We understand that the cosmos expands: we can quantify galaxy characteristics that inform us of both their distance and how rapidly they seem to travel away from us. The further removed they are, the more easily they seem to fade away. This implies that the cosmos expands in the context of Albert Einstein’s theory of General Relativity.
Based on the observable facts that we may conclude in reference to the current body of research compiled by the world’s greatest minds throughout history, it is safe to assume that there’s no limit to the possibilities out there. But just how many dimensions does the universe really have? The exact number is seemingly unquantifiable, and most likely won’t be answered any time soon. However, we know that there is a nearly infinite number of realms and dimensions exiting throughout the universe, and only time will tell what secret and revelations those worlds have in store for us, just waiting to be discovered.
