In a remarkable theoretical leap, scientists and conceptual physicists are delving into a new cosmological framework that expands well beyond the familiar ideas of universes and multiverses. Known as the “Metaverse”, this conceptual domain is emerging as a pivotal structure in the ever-expanding hierarchy of speculative cosmology.
According to emerging theories, the Metaverse is positioned as the third level in the cosmic hierarchy—above universes and multiverses, yet contained within even greater structures known as “Xenoverses”. A single Metaverse is theorized to span approximately **102.3 quintillion light-years** in diameter and may contain **hundreds or even thousands of multiverses**, each with their own unique physical laws and constants.
Unlike multiverses, which often consist of parallel universes operating under similar sets of natural laws, Metaverses are described as **hyperdimensional hubs** capable of transferring information, matter laws, and fundamental forces between the multiverses they contain. This interconnectivity, scientists suggest, may introduce instability, resulting in the creation of theoretical or virtual phenomena—such as “Virtual Omniverses” and “Imaginary Dodecahedra”—which exist only within the fabric of the Metaverse itself.
The formation of a Metaverse is equally extraordinary. It is hypothesized to occur when a Xenoverse’s boundary loops upon itself due to high-dimensional curvature, eventually fragmenting into a perfectly spherical structure. This process, though speculative, offers a potential framework for understanding the birth of large-scale universal systems beyond our current observational scope.
Interestingly, Metaverses may also contain anomalous multiverses that operate under radically different rules—posing significant barriers to interdimensional communication or theoretical contact between civilizations.
One particularly intriguing feature within some Metaverses is the so-called **”Ordinal Universe”**—a recursive structure replicated across all multiverses within the same Metaverse, each iteration existing at a reduced scale, creating a fractal-like cosmic signature.
Though still in the realm of theoretical physics and philosophical cosmology, the Metaverse concept is attracting growing attention from both academic circles and the wider public fascinated by the limits of reality. As humanity pushes forward in artificial intelligence, quantum theory, and digital simulations, the question of whether our universe is just one node in a much larger, interconnected Metaverse becomes increasingly relevant—not just scientifically, but existentially.
