speedises

Speedises are a hypothetical concept often explored in speculative fiction and theoretical physics. The term generally refers to objects or beings capable of exceeding the speed of light, a fundamental constant in our current understanding of the universe as described by Einstein's theory of special relativity. According to special relativity, as an object with mass approaches the speed of light, its mass and energy requirements increase infinitely, making it impossible to reach or surpass this cosmic speed limit.

The idea of speedises often arises in discussions about faster-than-light travel, which would allow for interstellar journeys within a human lifespan. Various theoretical mechanisms have been proposed to circumvent the speed of light barrier, such as warp drives or wormholes, which do not involve an object accelerating through space to exceed light speed but rather manipulating spacetime itself. However, these concepts remain highly speculative and lack experimental evidence. In fictional narratives, speedises can serve as plot devices to enable advanced civilizations or explore the consequences of defying known physical laws. The practical realization of speedises, if ever possible, would necessitate a profound revision of our current physical models.
