Accélants
Accélants are a hypothetical type of energy or substance that could enable faster-than-light (FTL) travel. The concept is often explored in science fiction and theoretical physics. In most theoretical frameworks, the creation or manipulation of accelerants would involve bypassing or manipulating the universal speed limit imposed by the speed of light, as described by Einstein's theory of special relativity. Various fictional explanations exist for how accelerants might function, often involving exotic matter, manipulated spacetime, or the harnessing of unknown cosmic forces. The scientific community has not discovered any evidence for the existence of accelerants, and their feasibility remains purely speculative. The development of such a substance or technology would have profound implications for interstellar travel and our understanding of the universe. Without a concrete scientific basis, accelerants remain a staple of imaginative storytelling rather than a practical consideration in current scientific research.
