FTL: Faster Than Light

FTL, or Faster Than Light travel, is a theoretical concept from science fiction that suggests traveling between stars faster than the speed of light. According to physics as we understand it, this isn't currently possible due to the immense energy required and the limitations of Einstein's relativity. However, in fiction, FTL often involves special technologies or phenomena—like warp drives or wormholes—that allow ships to bypass these physical limits and explore galaxies more efficiently. It remains a speculative idea, used to enable interstellar stories, rather than a proven or technically feasible method of space travel.
