The concept of a "Legion" coming from another universe is not based on scientific evidence or established scientific theories. The term "Legion" itself is often associated with fictional stories, such as comic books or movies, rather than scientific discourse.
In the realm of science, the existence of other universes is a topic of theoretical exploration, particularly in the field of cosmology. Concepts like the multiverse propose the existence of multiple universes, each with potentially different physical laws and properties. However, the multiverse hypothesis is speculative and still highly debated, lacking direct observational evidence.
Even if we consider the hypothetical existence of other universes, the idea of a "Legion" originating from another universe is purely speculative and falls within the realm of science fiction or imaginative storytelling. Without concrete evidence or a well-defined understanding of the nature and characteristics of other universes, it is not possible to assign any probabilities or chances to the existence or arrival of a "Legion" from another universe.
It's important to distinguish between scientific concepts and speculative fiction. While scientific exploration and theoretical hypotheses can push the boundaries of our understanding, they require rigorous testing and empirical evidence to gain acceptance within the scientific community.
